Risk Assessment of Human Exposure to 2-Methylnaphthalene, Phenanthrene and Didodecylphthalate via Consumption of Shrimps (Macrobrachium vollenhovenii) from Qua Iboe River Estuary, South-South Nigeria

Ibeno, one of the major oil producing communities in South-South Nigeria is a coastal commercial fishery hub that houses Axon-Mobil operational base and pharmaceutical/plastic industries. Shrimp species (Macrobrachium vollenhovenii) is a major aquatic food frequently consumed by inhabitants of the coastal area and those living hinterland, thus, being a major route of human exposure to 2-methylnaphthalene, phenanthrene and didodecyl phthalate in the area. The purpose of the study was to evaluate factors that determine bioaccumulation and assess the potential cancer and non-cancer risk posed by these contaminants through human (adult and children) exposure via shrimp’s consumption using gas chromatography-mass spectroscopy. The associated sediment showed higher mean concentrations of 2-methylnaphthalene, phenanthrene and didodecylphthalate at the two sites relative to those in fresh shrimp samples and factors such as size, lipid content, physicochemical property and environmental condition influenced the uptake of these contaminants. Besides water loss, the traditional drying process enhanced the levels of phenanthrene and didodecylphthalate in dry shrimps most likely due to combustion process and relatively low volatility, respectively and lowered the level of 2-methylnapthalene linked to its relatively high volatility. The potential of cancer and non-cancer development in human were highest via dry large shrimp consumption and followed the sequence: dry small shrimp > fresh large shrimp > fresh small shrimp and were within the USEPA reference standards. Although children were more vulnerable, the exposed individuals may not exhibit notable health-associated adverse effects in the near future. Thus, adequate advocacy is needed to sensitize those living in the catchments who often prefer dry shrimp in their meals on the adverse health implications of these contaminants for their survival and the need to maintain the health of the ecosystem.

Biomarkers of Human Exposure to Carcinogens: An Overview

Environmental, occupational, or dietary exposure to certain chemicals has been shown to be associated with carcinogenesis in humans. In the 18th century, for example, Percival Pott (1775) noted a high incidence of scrotal cancer in chimney sweeps, which he attributed to their exposure to soot and a concomitant lack of bathing. Subsequent epidemiological studies have identified a number of additional carcinogenic agents, including aromatic amine-based dyes (Case et al., 1954), cigarette smoke (Wynder and Graham, 1950), asbestos (Doll, 1955), vinyl chloride (Creech and

Occurrence of Human Exposure to Benzothiazoles and Benzotriazoles in Indoor Dust in Suizhou and Beijing,China

Benzothiazoles(BTHs)and benzotriazoles(BTRs)are an important group of industrial chemicals.Due to large scale and long-term applications,they have been released to various environmental media,including indoor dust,and subsequently elicited a variety of toxic effects.In this study,the concentrations and composition profiles of BTHs and BTRs in indoor dust from Suizhou and Beijing,China,were investigated.The median concentrations ofΣ_(6)BTHs in indoor dust samples from Suizhou and Beijing were 133 and 439 ng/g dw,respectively,whereas theΣ5BTRs concentrations from Suizhou and Beijing were 28.4 and 40.1 ng/g dw,respectively(dw=dry weight).BTH,2-OH-BTH,1-H-BTR,and 5-Me-1-H-BTR were the predominant compounds in the dust.Human exposure to such chemicals was further evaluated.The intake for the population in Suizhou(0.163–0.939 ng/kg bw/day)and Beijing(0.0347–0.200 ng/kg bw/day)was minor(bw=body weight).The obtained results in this study will be able to add insight into human exposure to BTHs and BTRs.This study will help to identify the behavior and fate of BTHs and BTRs in the environment,and thus to scientifically assess their risk of exposure.

Regulating wildlife conservation and food safety to prevent human exposure to novel virus

Epidemiological investigation suggested that the current outbreak of COVID-19 virus was associated with a seafood market,and COVID-19 has been identified a probable bat origin.Similar to SARS event in 2003,such a zoonotic disease showed an animal-to-person and even more serious person-to-person spread,and posed a significant threat to the global health and socio-economic development.We analyzed the association of both outbreaks with wildlife diet in China and proposed suggestions for regulating wildlife conservation and food safety to prevent human exposure to the novel virus,including increasing social awareness of hazards in eating wild animals,strengthening legislation on eating and trading of wild animals,improving the standards for food safety,and establishing market supervision mechanism.Regulatory intervention is not only critical for China but also for other countries where wildlife hunting is prevalent to prevent from novel virus exposures.

Occurrence,seasonal variation and human exposure to pharmaceuticals and personal care products in surface water,groundwater and drinking water in Lagos State,Nigeria

The occurrence of 28 pharmaceuticals and personal care products(PPCPs)was investigated in 17 surface water samples(rivers,canals,and lagoons),12 groundwater samples(wells and boreholes,which can also be consumed for drinking)and 8 drinking water samples(bottles and sachets)during dry and rainy seasons in Lagos state,Nigeria.The most prevalent compound detected in all samples was amoxicillin(an antibiotic)at median concentrations of 1614,238 and 358 ng/L in surface water,ground water and drinking water,respectively.This is of concern due to potential impact on development of antibioticresistant microbial strains.Other frequently-detected compounds include acetaminophen,nicotine,ibuprofen,and codeine with detection frequencies of more than 70%.Investigation of seasonal variability revealed that glyburide,caffeine,naproxen and diclofenac concentrations were significantly(P<0.05)higher during the dry season(winter),while Nicotine and Codeine levels were higher during the rainy season(summer).The factors influencing such seasonal variability include:dilution by extensive rainfall,agricultural activity(for nicotine)and usage patterns of pharmaceuticals among the local community.Measured concentrations in drinking water samples were used to assess inadvertent human exposure to PPCPs in Nigerian adults.Results revealed average daily exposures of 81,14 and 3 ngƩPPCPs/kg BW/day via drinking borehole,sachet water and bottled water,respectively.While there exists no health-based limit value(HBLV)for chronic exposure to mixtures of PPCPs,our results raise concern and warrant further investigation of the potential health implications of such unintended PPCPs exposure.

Polybrominated diphenyl ethers and“novel”brominated flame retardants in floor and elevated surface house dust from Iraq:Implications for human exposure assessment

Concentrations of polybrominated diphenyl ethers(PBDEs)and selected novel brominated flame retardants(NBFRs)were measured in indoor dust from the living areas of 18 homes in Basrah,Iraq.This is the first report of contamination of the Iraqi environment with these chemicals.To evaluate the implications for human exposure,samples were collected from both the floor and from elevated surfaces like tables,shelves and chairs.When normalised for the organic carbon content of the dust sample,concentrations in elevated surface dust of BDE-99,BDE-209,pentabromoethylbenzene(PBEB),bis(2-ethylhexyl)3,4,5,6-tetrabromophthalate(BEH-TEBP),and decabromodiphenylethane(DBDPE)exceeded significantly(p<0.05)those in floor dust from the same rooms.This suggests that previous studies that base estimates of adult exposure via dust ingestion on floor dust,may underestimate exposure.Such underestimation is less likely for toddlers who are far more likely to ingest floor dust.Concentrations of PBDEs and NBFRs in indoor dust from Basrah,Iraq are at the lower end of levels reported elsewhere.The PBDE contamination pattern in our samples suggests that use in Iraq of the Deca-BDE formulation,exceeds substantially that of Penta-BDE,but that use of the Octa-BDE formulation has been higher in Iraq than in some other regions.Reassuringly,our estimates of exposure to our target BFRs via dust ingestion for the Iraqi population fall well below the relevant health-based limit values.

Organophosphate esters in indoor and outdoor dust from Iraq:Implications for human exposure

Concentrations of 6 organophosphate esters(OPEs)were determined in 60 indoor(ID)and outdoor(OD)dust samples collected from 20 homes from Basrah,Iraq.From each home,two ID samples were collected,one from elevated surfaces(ESD)and one from the floor(FD)of the living room;while the OD samples were collected from the front yard of the same house.Total S6OPEs concentrations in dust samples ranged between 681 and 17900 ng/g with median concentrations of 5950,3590 and 1550 ng/g in ESD,FD and OD samples,respectively.Chlorinated OPEs were the most abundant compounds,contributing mean percentages of 88%,85%and 78%toΣ_(6)OPEs in ESD,FD and OD,respectively,with tris(1-chloro-2-propyl)phosphate(TCIPP)dominant.Concentrations of our target OPEs in ESD significantly exceeded those in FD(p<0.05)for tris(2-chloroethyl)phosphate(TCEP)and tris(1,3-dichloro-2-propyl)phosphate(TDCIPP).Ratios of median concentrations of OPEs in ID:OD ranged from 1.5 for tri-n-butyl phosphate(TNBP)to 8.0 for TCEP,indicating the significance of indoor sources.Concentrations of chlorinated OPEs in ID were moderately correlated(R=0.522-0.591,P<0.05)with those in OD samples,suggesting interchange of OPEs between the two environments.Concentrations of OPEs in OD from houses with a contiguous front yard car porch exceeded those in OD from houses without a car porch and were significantly higher(P<0.05)for TCEP,TCIPP and 2-ethylhexyl diphenyl phosphate(EHDPP).Emissions from parked cars and the associated home are likely sources of OPEs in the OD area.Based on the concentrations reported here,the estimated daily intake(EDI)for the Iraqi population through house dust ingestion are all well below the relevant reference dose(RfD)values.

Medical Radiation Exposure and Human Carcinogenesis-Genetic and Epigenetic Mechanisms

Ionizing radiation （IR） is a potential carcinogen. Evidence for the carcinogenic effect of IR radiation has been shown after long-term animal investigations and observations on survivors of the atom bombs in Hiroshima and Nagasaki. However, IR has been widely used in a controlled manner in the medical imaging for diagnosis and monitoring of various diseases and also in cancer therapy. The collective radiation dose from medical imagings has increased six times in the last two decades, and grow continuously day to day. A large number of evidence has revealed the increased cancer risk in the people who had frequently exposed to x-rays, especially in childhood. It has also been shown that secondary malignancy may develop within the five years in cancer survivors who have received radiotherapv, because of IR-mediated damage to healthy cells. In this article, we review the current knowledge about the role of medical x-ray exposure in cancer development in humans, and recently recognized epigenetic mechanisms in IR-induced carcinogenesis.

Exposure of aboriginal people to methylmercury due to gold mining in the Amazon, Brazil

This paper outlines the results of our study aiming at evaluating the actual extent of human exposure to Hg mainly in Tapajos River Basin in central Amazonia, which is considered to be the oldest and most productive gold mining area in the Amazon. Human hair and blood as well as fish samples were collected from gold mining areas and various fishing villages located at different distances from main gold mining areas, and analyzed for total mercury(T Hg) and methylmercury (MeHg) with new methods recently being developed in our laboratory. The results to date showed the inhabitants of fishing villages particularly in the upstream Tapajos areas were constantly exposed to MeHg at abnormally high levels, with little confounding exposure to inorganic Hg. A highly significant correlation between Hg in hair and blood was observed in fishing villages, and the ratios of hair Hg to blood Hg were very close to 250g, generally established for MeHg. While, the levels of MeHg in hair and blood of gold miners and goldshop workers were low, indicating that they were mainly exposed to Hg in inorganic form. From these data, together with the levels of MeHg in fish, Hg contamination mechanisms are discussed.

Evaluating human exposure to antibiotic resistance genes

Antibiotic resistance is an escalating global concern,leading to millions of annual fatalities.Antibiotic resis-tance genes(ARGs)present in bacteria equip them to withstand the effects of antibiotics.Intra-and interspeci-fic ARGs transmission through horizontal gene transfer further exacerbates resistance dissemination.The presence of ARGs in the environment heightens the probability of human exposure via direct inhalation,inges-tion,or contact with polluted air,food,or water,posing substantial biosafety and health hazards.Consequently,ARGs represent a critical focal point in public health and environmental safety and are classified as emerging contaminants.This perspective underscores the necessity to assess ARG exposure within the One Health framework and to accord greater attention to the mitigation strategies and tactics associated with ARGs.2024 Chinese Medical Association Publishing House.Published by Elsevier BV.

Male-mediated developmental toxicity

Male-mediated developmental toxicity has been of concern for many years. The public became aware of male-mediated developmental toxicity in the early 1990s when it was reported that men working at Sellafield might be causing leukemia in their children. Human and animal studies have contributed to our current understanding of male-mediated effects. Animal studies in the 1980s and 1990s suggested that genetic damage after radiation and chemical exposure might be transmitted to offspring. With the increasing understanding that there is histone retention and modification, protamine incorporation into the chromatin and DNA methylation in mature sperm and that spermatozoal RNA transcripts can play important roles in the epigenetic state of sperm, heritable studies began to be viewed differently. Recent reports using molecular approaches have demonstrated that DNA damage can be transmitted to babies from smoking fathers, and expanded simple tandem repeats minisatellite mutations were found in the germline of fathers who were exposed to radiation from the Chernobyl nuclear power plant disaster. In epidemiological studies, it is possible to clarify whether damage is transmitted to the sons after exposure of the fathers. Paternally transmitted damage to the offspring is now recognized as a complex issue with genetic as well as epigenetic components.

Distribution of rare earth elements in agricultural soil and human body(scalp hair and urine) near smelting and mining areas of Hezhang, China

Rare earth elements （REEs） in recent decade are widely used and lead to the accumulation of REE in the environment and human body. The aim of this study was to evaluate the concentrations of REEs in soil and human body （scalp hair and urine） of peo-ple living in agricultural soil near smelting and mining areas in Hezhang County, China. The results showed that mean concentrations of determined REEs in agricultural soil from smelting areas were higher than background. However, concentration was slightly higher in soil in mining area. In addition, REEs concentrations of hair and urine in smelting areas were higher than those in mining areas.ΣREEs for soil in mining and smelting areas were 177.79 and 277.06 mg/kg, respectively.ΣREEs for hair in mining and smelting were 1.13 and 1.55 mg/kg, respectively, andΣREEs for urine in mining and smelting were 0.58 and 0.59 μg/L, respectively. Results showed that La, Ce and Nd were enriched in soil, hair and urine. Eu in smelting area showed a positive anomaly. In smelting and mining areas, females were more likely than male to expose to REEs. The relationship between REEs concentration and age group showed that hair’s high concentrations of REE existed in 18–40 years age for people from smelting areas and females from mining areas. While high concentrations distributed in the age of 41–65 for males from mining area. However, urine did not present similar distribution for different age group. Compared with hair and urine, soil showed the same distribution of REEs. And according to the Ce/Ce＊ value vs. LaN/YbN ratio showed that hair and soil tended to increase, with the stability of Ce/Ce＊ value. Thus the distri-bution of REEs in soil was closely related with the accumulation in human body. This is a preliminary study which may be suggested to the other research, and this study data may be useful for adding up the data pool on REEs levels in China.

Burden levels of polychlorinated dibenzo-p-dioxins, dibenzofurans, and polychlorinated biphenyls in typical edible meat animals

The concentrations and distributions of polychlorinated dibenzo-p-dioxins(PCDDs), polychlorinated dibenzofurans(PCDFs), and polychlorinated biphenyls(PCBs) in the whole blood and meat of eight typical edible animals(chicken, donkey, horse, cattle, rabbit, sheep, duck,and pig) were illustrated. Total concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs) and PCBs(on a basis of liquid volume) in animal bloods were 142-484 pg/L and 46-62 ng/L, respectively. Total concentrations of PCDD/Fs and PCBs(on a basis of dry weight(dw) and lipid weight(lw)) in animal meat samples were 0.47-1090 pg/g dw(0.47-4513 pg/g lw) and 7.2-23 ng/g dw(10-776 ng/g lw), respectively. TEQs for both PCDD/Fs and PCBs in animal blood and meat samples were(67 ± 27) pg/L and(5.3 ± 14) pg/g dw(24± 56 pg/g lw), respectively. Besides, the dietary intakes of PCDD/Fs and PCBs were also estimated. Chicken and pig contributed more TEQs than other animals. Chicken contributed the most(95%) with high toxicity, followed by pig(3.4%) with high consumption. The dietary intake of chicken might pose risks to consumers who prefer to eat chicken products, who should comprehensively consider the essential nutrients and contaminants in food during dietary intake.

Arsenic speciation in freshwater fish:challenges and research needs

Food and water are the main sources of human exposure to arsenic.It is important to determine arsenic species in food because the toxicities of arsenic vary greatly with its chemical speciation.Extensive research has focused on high concentrations of arsenic species in marine organisms.The concentrations of arsenic species in freshwater fish are much lower,and their determination presents analytical challenges.In this review,we summarize the current state of knowledge on arsenic speciation in freshwater fish and discuss challenges and research needs.Fish samples are typically homogenized,and arsenic species are extracted using water/methanol with the assistance of sonication and enzyme treatment.Arsenic species in the extracts are commonly separated using high-performance liquid chromatography(HPLC)and detected using inductively coupled plasma mass spectrometry(ICPMS).Electrospray ionization tandem mass spectrometry,used in combination with HPLC and ICPMS,provides complementary information for the identification and characterization of arsenic species.The methods and perspectives discussed in this review,covering sample preparation,chromatography separation,and mass spectrometry detection,are directed to arsenic speciation in freshwater fish and applicable to studies of other food items.Despite progress made in arsenic speciation analysis,a large fraction of the total arsenic in freshwater fish remains unidentified.It is challenging to identify and quantify arsenic species present in complex sample matrices at very low concentrations.Further research is needed to improve the extraction efficiency,chromatographic resolution,detection sensitivity,and characterization capability.

Emerging organic contaminants of liquid crystal monomers:Environmental occurrence,recycling and removal technologies,toxicities and health risks

Liquid crystal monomers(LCMs)are a family of synthetic organic chemicals applied in the liquid crystal displays(LCDs)of various electric and electronic products(e-products).Due to their unique properties(i.e.,persistence,bioaccumulative potential,and toxicity)and widespread environmental distributions,LCMs have attracted increasing attention across the world.Recent studies have focused on the source,distribution,fate,and toxicity of LCMs;however,a comprehensive review is scarce.Herein,we highlighted the persistence and bioaccumulation potential of LCMs by reviewing their physical–chemical properties.The naming rules were suggested to standardize the abbreviations regarding LCMs.The sources and occurrences of LCMs in different environmental compartments,including dust,sediment,soil,leachate,air and particulate,human serum,and biota samples,were reviewed.It is concluded that the LCMs in the environment mainly originate from the usage and disassembly of eproducts with LCDs.Moreover,the review of the potential recycling and removal technologies regarding LCMs from waste LCD panels suggests that a combination of natural attenuation and physic-chemical remediation should be developed for LCMs remediations in the future.By reviewing the health risks and toxicity of LCMs,it is found that a large gap exists in their toxicity and risk to organisms.The fate and toxicity investigation of LCMs,and further investigations on the effects on the human exposure risks of LCMs to residents,especially to occupational workers,should be considered in the future.

Consumption of rice and fish in an electronic waste recycling area contributes significantly to total daily intake of mercury

Mercury is a global pollutant due to its widespread use,emission,and long-range transport（Blum,2013;Pacyna et al.,2010）.It is considered a priority pollutant due to its neurological toxicity,persistence,and bioaccumulation（Pacyna et al.,2010;Sharma et al.,2015）.Mercury pollution can occur when products that contain mercury are improperly disposed of and mercury is released into the air,water,and soil（Zhang and Wong,2007）.An estimated 22%of the annual world usage of mercury is in electrical equipment such as batteries,thermometers,and discharge lamps,and electronic devices such as monitors and

Health implications of engineered nanoparticles in infants and children

Background:The nanotechnology boom and the ability to manufacture novel nanomaterials have led to increased production and use of engineered nanoparticles(ENPs).However,the increased use of various ENPs inevitably results in their release in or the contamination of the environment,which poses significant threats to human health.In recent years,extraordinary economic and societal benefits of nanoproducts as well as their potential risks have been observed and widely debated.To estimate whether ENPs are safe from the onset of their manufacturing to their disposal,evaluation of the toxicological effects of ENPs on human exposure,especially on more sensitive and vulnerable sectors of the population(infants and children)is essential.Data sources:Papers were obtained from PubMed,Web of Science,and Google Scholar.Literature search words included:"nanoparticles","infants","children","exposure","toxicity",and all relevant cross-references.Results:A brief overview was conducted to 1)characterize potential exposure routes of ENPs for infants and children;2)describe the vulnerability and particular needs of infants and children about ENPs exposure;3)investigate the current knowledge about the potential health hazards of ENPs;and 4)provide suggestions for future research and regulations in ENP applications.Conclusions:As the manufacturing and use of ENPs become more widespread,directed and focused studies are necessary to measure actual exposure levels and to determine adverse health consequences in infants and children.

Occurrence, variations, and risk assessment of neonicotinoid insecticides in Harbin section of the Songhua River, northeast China

Neonicotinoid insecticides(NNIs)have been intensively used and exploited,resulting in their presence and accumulation in multiple environmental media.We herein investigated the current levels of eight major NNIs in the Harbin section of the Songhua River in northeast China,providing the first systematic report on NNIs in this region.At least four NNIs in water and three in sediment were detected,with total concentrations ranging from 30.8 to 135 ng L^(-1) and from 0.61 to 14.7 ng g^(-1) dw,respectively.Larger spatial variations in surface water NNIs concentrations were observed in tributary than mainstream(p<0.05)due to the intensive human activities(e.g.,horticulture,urban landscaping,and household pet flea control)and the discharge of wastewater from many treatment plants.There was a significant positive correlation(p<0.05)between the concentrations of residual imidacloprid(IMI),clothianidin(CLO),and S4NNIs in the sediment and total organic carbon(TOC).Due to its high solubility and low octanol-water partition coefficient(Kow),the sediment-water exchange behavior shows that NNIs in sediments can re-enter into the water body.Human exposure risk was assessed using the relative potency factor(RPF),which showed that infants have the highest exposure risk(estimated daily intake(SIMIeq EDI):31.9 ng kg^(-1) bw$d^(-1)).The concentration thresholds of NNIs for aquatic organisms in the Harbin section of the Songhua River were determined using the species sensitivity distribution(SSD)approach,resulting in a value of 355 ng L^(-1) for acute hazardous concentration for 5%of species(HC5)and 165 ng L^(-1) for chronic HC5.Aquatic organisms at low trophic levels were more vulnerable to potential harm from NNIs.

Chlorinated paraffins in the technosphere:A review of available information and data gaps demonstrating the need to support the Stockholm Convention implementation

Chlorinated paraffins(CPs)have been produced for a wide range of applications,mostly in open uses,such as metalworking fluids,lubricants,coolants or additives in consumer goods.The production volume is more than one million tonnes requiring control of the lifecycle of these persistent and bioaccumulative chemicals.In May 2017,the Stockholm Convention amended its Annex A to list short chain chlorinated paraffins(SCCPs)as a Persistent Organic Pollutant(POP).Additionally,a limit for the presence of SCCPs in other CP mixtures was set at 1%by weight.CPs can be released to the environment throughout their lifecycle.Therefore,the major objective of this review was to assess and compile information on SCCPs and other CPs regarding their lifecycle in the technosphere to support the Stockholm Convention implementation.A few studies have assessed CP production plants and contamination in the surrounding environments.However,there was no systematic investigation of release routes from production and no assessment of associated landfills,even though these are known major pollution sources at other organochlorine production sites.Some studies have reported that industrial areas,where CPs have likely been used,have elevated levels of CPs in sediments and soil.However,although CPs are largely released when used as metalworking fluids or lubricants,no systematic assessment of releases has been conducted at the thousands of sites where CPs are used in high volumes.Many CPs,mainly medium chain chlorinated paraffins(MCCPs)and SCCPs,are used as additives in the production of consumer goods,resulting in exposure risks.Levels above the European Union regulation for SCCPs of 1500 mg kg^-1 and up to approx.20%are frequently found.The end-of-life management of CP-containing products is difficult since no labelling requirement exists even for products containing SCCPs.The Stockholm Convention prohibits the recycling of SCCP-containing products,which will result in challenges recycling the impacted waste categories.The activities under the Stockholm Convention related to SCCPs,such as the inventory,phase-out,and management of impacted products,provide opportunities to address existing data gaps and challenges.Special attention needs to be given to developing countries with lacking analytical capacity as well as waste management and destruction capacity.

Translocation of pharmaceuticals and personal care products(PPCPs)into plant tissues:A review

Occurrence and fate of pharmaceuticals and personal care products(PPCPs)in the environment and the potential consequences for human health is of serious concern.In the current review,we have tried to provide a summary on recent research and an overview of PPCPs in the soil-plant systems,in the environment and analytical methods used for determination of PPCPs in plant tissues.Further review also include highlights on the fate of PPCPs in agricultural soils receiving treated wastewater irrigation or biosolids amendment,and plant uptake of PPCPs under laboratory and field conditions.PPCPs have shown to be released to the environment and may cause significant impacts on different environmental aspects.Plant roots showed their abilities to uptake and transfer of PPCPs into plant tissues.The uptake of PPCPs varies depending on crop type and physiochemical properties of the chemical compound that were exposed.Consumption of contaminated crops with PPCPs residues may cause serious health problems.Liquid chromatography in combination with mass chromatography was found to be the most popular analytical instrument used for PPCPs determination in different samples.Finally,the information gaps and few suggestions for future research have been proposed in this review.
