An Estimation of the Daily Intake of Di(2-ethlhexyl) Phthalate(DEHP) among Workers in Flavoring Factories

Objective To estimate the daily intake of DEHP among workers in flavoring factories. Methods 71 workers in two flavoring manufacturers, 27 administrators in those factories and 31 laboratory technicians in a research institute were recruited and assigned to exposure group, control group 1 and control group 2 respectively. Their urinary DEHP metabolites, mono（2-ethylhexyl） phthalate （MEHP）, mono-（2-ethyl-5-hydroxyhexyl） phthalate （MEHHP）, mono-（2-ethyl-5-oxohexyl） phthalate （MEOHP）, were detected by isotope dilution-ultra performance liquid chromatography-tandem mass spectrometry（UPLC-MS/MS）. The urinary metabolites concentrations were converted into DEHP intake levels using two pharmacokinetic models： the urine creatinine-excretion （UCE） one and the urine volume （UV） one. Results No significant differences were found among the three groups. Based on the urinary concentrations of Z3MEHP, we got a median daily DEHP intake of 3.22 or 1.85 μg/kg body-weight/day applying the UV or UCE models respectively. Depending on the UV model, three subjects （2.34%） exceeded the RfD value given by US EPA and the P50 of estimate daily DEHP intakes accounted for 16.10% of the RfD value. No subjects exceeded the limitation depending on the UCE model. Conclusion The workers in flavoring factories were not supposed to be the high DEHP exposure ones and their exposure level remained at a low risk.

Mercury levels and estimated total daily intakes for children and adults from an electronic waste recycling area in Taizhou, China: Key role of rice and fish consumption

In order to assess the potential health risks of Hg pollution, total mercury（T–Hg） and methyl mercury（Me Hg） concentrations were determined in air, dust, surface soil, crops, poultry,fish and human hair samples from an electronic waste（e-waste） recycling area in Taizhou,China. High concentrations of T–Hg and Me Hg were found in these multiple matrices, and the mean concentration was 30.7 ng/m3 of T–Hg for atmosphere samples, 3.1 μg/g of T–Hg for soil, 37.6 μg/g of T–Hg for dust, 20.3 ng/g of Me Hg for rice and 178.1 ng/g of Me Hg for fish,suggesting that the e-waste recycling facility was a significant source of Hg. The inorganic Hg（I–Hg） levels（0.84 μg/g） in hair samples of e-waste workers were much higher than that in the reference samples. Pearson＇s correlation coefficients showed that strong positive correlations（p 〈 0.01） between hair I–Hg and time staying in industrial area（r = 0.81） and between Me Hg and fish consumption frequency（r = 0.91）, imply that workers were mainly exposed to Hg vapor through long-time inhalation of contaminated air and dust, while other population mainly exposed to Me Hg through high-frequency fish consumption. The estimated daily intakes of Hg showed that dietary intake was the major Hg exposure source,and Hg intakes from rice and fish were significantly higher than from any other foods. The estimated total daily intakes（TDIs） of Me Hg for both children（696.8 ng/（kg·day）） and adults（381.3 ng/（kg·day）） greatly exceeded the dietary reference dose（Rf D） of 230 ng/（kg·day）,implying greater health risk for humans from Hg exposures around e-waste recycling facilities.

Relationships between daily total fluoride intake and dental fluorosis and dental caries

Objective： To explore the relationships between the daily total intake of fluoride, dental fluorosis and dental caries. Methods： An epidemiological method was used to investigate the daily total intake of fluoride, dental fluorosis, and dental caries among 236 and 290 children aged 8-13 years in a severe endemic area and in a non-fluorosis control area, respectively. The children were divided into eight subgroups according to each child＇ s estimated daily total intake of fluoride. The prevalence of dental fluorosis and dental caries in each group was calculated. Results： As expected, elevated levels of fluoride intake were significantly associated with a higher prevalence of dental fluorosis and an increasing amount of more severe defect dental fluorosis. When the daily total F intake was 2.78 mg/child/day, the prevalence of dental fluorosis was nearly 100%, with the prevalence of defect dental fluorosis increasing with increasing fluoride intake. There was also a significant negative（inverse） dose-response relationship between the daily total intake of fluoride and the overall prevalence of dental caries, the prevalence of which decreased when the daily total intake of fluoride increased up to 3.32 mg/child/day. However, at higher levels of daily total intake of fluoride the prevalence of dental caries increased, giving rise to a U-shaped dose-response relationship curve. Conclusion： It is important to monitor total fluoride exposure and protect children from excessive fluoride intake, especially during the years of tooth development.

Prescription and Delivery of Enteral Nutrition for ICU Patients: A Case Study of a Hospital in the Interior of Brazil

Background: The objective of the present study was to evaluate during one year the total delivery of volume, calories, and proteins and compare them with the total prescribed to ICU patients using ENT (Enteral Nutrition Therapy) exclusively. Methods: Data on the prescribed or infused volume, calories, and protein, as well as their respective needs for each individual, were collected. Anthropometric parameters and age data were also collected from the medical records of 41 patients admitted to the intensive care unit. Results: Prescribed versus infused enteral diet volume was presented in 5 weeks which corresponds to the maximum duration of ICU treatment. Regarding sampling, the majority corresponded to elderly people (>64 years old) and males (63.4%). The total average prescribed was 719.2 mL of enteral diet on an average of 649.7 mL delivered. In addition, there was no significant difference between the prescribed and delivered volume, caloric value, and protein content of the diet only in the last week of hospitalization, which corresponded to the range of 29 - 36 days. Several factors make it difficult to reach the patient’s caloric and protein recommendations. Most of the reasons are not recorded, corresponding to 57.1%, indicating the difficulty of assessing the inadequacy of the prescribed and delivered volume. Conclusion: To our knowledge, this is the first time that a prescription vs. delivery assessment has been carried out for patients in the Brazilian Midwest. In addition, although our research is a difficulty reported worldwide (in most hospitals), we also provide opportunities for how the problem was solved in our case, which may contribute to other cases.

Levels of Heavy Metals in Some Vegetables and Human Health Risk Assessment in Loumbila Area, Burkina Faso

Contamination by heavy metals of soil, water and agricultural products is currently a major problem of environmental pollution in the world. The consumption of plants contaminated with heavy metals can be the cause of diseases such as cancers, the number of cases of which is only growing. The objective of this study was to determine the concentration of copper (Cu), chromium (Cr), zinc (Zn), lead (Pb), nickel (Ni), and cadmium (Cd) in plants from the vegetable farm of LOUMBILA and the assessment of health risks linked to the consumption of plants. In this paper, the concentration of heavy metal in vegetable was measured using the model AANALYST 200 flame atomic absorption spectrometer from PERKIN ELMER. The level of Zn in the vegetables from Loumbila vegetable farms ranged between 42.95 mg/kg and 78 mg/kg. The concentrations of Zn in the studies vegetables were higher than the permissible levels set by FAO/WHO (20 mg/kg). The concentration Pb in vegetables varied from 1.73 mg/kg to 27.02 mg/kg. All concentrations of Pb in vegetable were higher than the permissible levels set by FAO/WHO (0.3 mg/kg). Daily intake of Ni, Cr and Pb was higher than the MTDI, so consumption of vegetables from Loumbila vegetable farms can lead to health problems related to Ni, Cr and Pb. In vegetables from LOUMBILA, the estimated daily intake decreased in the following order: Zn > Cu > Pb > Ni > Cr. The Hazard index values for carrot, onion, lettuce, green bean and onion leaves were greater than (>) one (1) which indicates that there might be a potential health risk to those consuming these vegetables. The Target Cancer Risk (TCR) analysis also revealed the potential cancer risk induced by Cu, Ni, Zn, Cr and Pb due to the consumption of carrot, onion leaves, onion, lettuce, green bean, and bell pepper because their TCR values were above the threshold.

Assessing the health risk of heavy metals in vegetables to the general population in Beijing,China

A systematic survey of As, Cd, Cr, Cu, Ni, Pb and Zn concentrations in vegetables from 416 samples （involving 100 varieties） in Beijing was carried out for assessing the potential health risk to local inhabitants. The results indicated that the metal concentrations in vegetables ranged from 〈 0.001 to 0.479 μg/g fresh weight （fw） （As）, 〈 0.001 to 0.101 μg/g fw （Cd）, 〈 0.001 to 1.04 μg/g fw （Cr）, 0.024 to 8.25μg/g fw （Cu）, 0.001 to 1.689 μg/g fw （Ni）, 〈 0.001 to 0.655 μg/g fw （Pb） and 0.01 to 25.6 μg/g fw （Zn）, with average concentrations of 0.013, 0.010, 0.023, 0.51, 0.053, 0.046 and 2.55 μg/g fw, respectively. The results showed that the concentrations of As, Cr, Cu, Cd, Pb and Ni in vegetables from open-fields were all significantly higher than those grown in greenhouses. In addition, in local-produced vegetables, all HMs except Zn were significantly higher than those in provincial vegetables. The estimated daily intake （EDI） of As, Cd, Cr, Cu, Ni, Pb and Zn from vegetables was 0.080, 0.062, 0.142, 3.14, 0.327, 0.283 and 15.7 μg/（kg body weight （bw）.d） for adults, respectively. Arsenic was the major risk contributor for inhabitants since the target hazard quotient based on the weighted average concentration （THQw） of arsenic amounted to 44.3% of the total THQ （TTHQ） value according to average vegetable consumption. The TTHQ was lower than 1 for all age groups, indicating that it was still safe for the general population of Beijing to consume vegetables.

Assessment of Exposure to Polybrominated Dipheny Ethers via Inhalation and Diet in China

Objective This paper is to assess the current status of polybrominated diphenyl ethers（PBDEs） contamination in the environment in China and estimate the exposure to PBDEs in non-occupational populations.Methods A total of 80 research papers published from January 2001 to October 2013 were selected.Geographic information system（GIS） was used in mapping PBDE concentrations and distributions in environmental media.Ni＇s model was applied to calculate ∑PBDE-intake via the intakes of contaminated food,water and air in the Pearl River Delta and Yangtze River Delta.Results BDE-209 was found to be the major PBDE congener in the environmental media and food in China.PBDE concentrations varied among different areas,among which the contamination in Guangdong Province was most serious.Daily intake of ∑PBDEs was 225.1-446.0 ng/d for adults in the Pearl River Delta,which was higher than the intake for those living in the Yangtze River Delta（148.9-369.8 ng/d）.Conclusion PBDEs are ubiquitous in the environment of China.The estimated PBDEs daily dietary intake is comparable with that in European countries.

Heavy Metals in Native Potato and Health Risk Assessment in Highland Andean Zones of Junín, Peru

Heavy metals are transferred from the abiotic environment to living organisms, accumulate in food, contaminate the food chain, and are an important route of human exposure involving a potential health risk. In this study, the concentrations of heavy metals (Cd, Fe, Pb, Zn and As) in agricultural soils and tubers of Solanum tuberosum spp. andigena (native potato) were evaluated. Also, an assessment of the health risk associated with the daily intake by the local population was performed in the four districts of the department of Junín, between altitudes of 3800 m to 4200 m. The heavy metals concentrations in soils with native potato cultivation followed the following decreasing order of Fe > Zn > Pb > As > Cd, with values below national standards. The heavy metals content in native potatoes was below the limits recommended by international standards with the exception of Pb. The bioconcentration factor (BCF) for the two native potato varieties in decreasing order was Zn > Cd > Pb > As > Fe, all less than 0.5. The estimated daily intake of metals (EDIM) in adults and children through the consumption of native potatoes was higher for Fe and Zn. The threshold carcinogenic risk values (TCR) for As exceeded the safety limits 1 × 10-4. It is concluded that the residents in the four high Andean localities would be exposed to carcinogenic adverse health effects associated with the intake of native potatoes. It is important to monitor the concentration of As and other heavy metals in the Andean soils and crops in order to implement a soil and crop management program to ensure food quality.

Macro-nutrients in edible parts of food crops in the region of Moanda,Gabon

The assessment of nutritive foodstuffs quality is an important step in the estimation of dietary intake of metals. This study aimed to assess accumulation and the daily intake of macro-elements magnesium, calcium, potassium and sodium in edible parts of plants grown in Moanda area. The ranges of concentrations were 246 - 5645 mg/kg, 1167 - 35105 mg/kg, 158 - 12563 mg/kg and 88 - 795 mg/kg for Mg, Ca, K and Na, respectively. Mg and K levels were significantly higher in fruits than in tubers. The trend of accumulation in the edible parts of plants was generally: Ca > K > Mg > Na. The daily intakes of Mg and Ca were the highest and indicated food crops in Moanda had a good nutritive quality.

Assessment of Heavy Metal Concentration and Evaluation of Health Risk of Some Vegetables Cultivated in Loumbila Farmland, Burkina Faso

Vegetables such as spinach, African eggplant, cabbage, eggplant, okra, chili peppers and tomatoes are found in our everyday foods and are the most important dietary source of nutrient. But, it becomes deleterious to human as well as animals as it accumulates toxic metals in their tissue when grown in contaminated soil. The mostly consumed vegetables like spinach, African eggplant (fruit and leaves), Corchorus olitorius leaf, Amaranthus hybridus leaf, cabbage, eggplant, okra, pepper and tomato were collected from Loumbila market gardening. Heavy metals copper (Cu), nickel (Ni), lead (Pb), chromium (Cr), cadmium (Cd) and zinc (Zn) were measured using atomic absorption spectrophotometer (AAS) model AANALYST 200 from PERKIN ELMER. The results of this study showed that the concentrations of lead (0.49 to 8.59 mg/kg) and zinc (20.73 to 71.29 mg/kg) in spinach, African eggplant (fruit and leaves), Corchorus olitorius leaf, Amaranthus hybridus leaf, cabbage, eggplant, okra, pepper and tomato exceeded the permissible level of FAO and WHO standard. The daily plant metal intake for Cd (0.001 - 0.015 mg/kg), Pb (0.041 - 0.730 mg/kg), and Cu (0.703 - 1.543 mg/kg) is higher than the recommended daily intake of metals but does not exceed the tolerable limit. The calculated values of the health risk indices show high values for Cd, Pb, Zn, Ni and Cu while low values are observed for Cr. Except for Cr, the IRS evaluated for all the studied metals were greater than one (IRS > 1). This implies that exposed populations are susceptible to developing diseases linked to the following metals: Cd, Pb, Zn, Ni and Cu.

Optimal fluid intake in daily diet: Avicenna's view

Adequate daily water consumption is an important factor of keeping regular homeostasis. However, the best quantity of daily water consumption for a healthy individual is not virtually stated in the literature. Despite the dearth of evidence-based recommendations, it is commonly thought that ingesting eight glasses of water a day is good for a healthy person. Avicenna had a unique viewpoint. He believed that daily water intake depended on numerous elements together with age, intercourse, body temperament, season, occupation and various internal and external elements. He also cited a few essential and usefu measures regarding proper water consumption, which have additionally been emphasized in Islamic hadiths.

Preliminary Study on Feeding Habits of Anthocidaris crassispina

Abstract Employing experimental-ecological methods, the feeding and vitality of adult Anthocidaris crassispina were investigated. The results showed that A. cras- sispina exhibited an obvious preference on five different seaweeds, with the preference order of Betaphycus gelatinum 〉 Sargassum hemiphyllum 〉 Gelidium amansii 〉 Ulva lactuca 〉 Codium fragile. The daily feed intake of A. crassispina differed among U. lactuca, S. hemiphyllum and B. gelatinum. The feeding was affected by water temperature, seaweed species and body weight. The optimal vitality and feed intake were observed under 23 -27℃, which were inhibited under whether too higher or too lower temperature. Under the optimal temperature for feeding, the daily feed intake of adult A. crassispina assumed an exponentially-decreasing trend with increase of body weight.

Residual levels and health risk assessment of trace metals in Chinese resident diet

Large-scale metal contamination across the food web is an intractable problem due to increasing pollutant emissions,atmospheric transport,and dry and wet deposition of elements.The present study focus on several trace metals that are rarely studied but have special toxicity,including tin(Sn),antimony(Sb),gold(Au),hafnium(Hf),palladium(Pd),platinum(Pt),ruthenium(Ru),tellurium(Te)and iridium(Ir).We investigated trace metals residues and distribution characteristics,and further evaluated the potential health risks from major daily food intakes in 33 cities in China.Sn,Sb,Ir,Hf,and Au were frequently detected in food samples with the concentrations ranged from ND(not detected)to 24.78μg/kg ww(wet weight).Eggs exhibited the highest residual level of all detected metals(13.70±14.70μg/kg ww in sum),while the lowest concentrations were observed in vegetables(0.53±0.17μg/kg ww in sum).Sn accounting for more than 50%of the total trace metals concentration in both terrestrial and aquatic animal origin foods.In terrestrial plant origin foods,Sn and Ir were the most abundant elements.Hf and Au were the most abundant elements in egg samples.In addition,Sb and Ir showed a clear trophic dilution effect in terrestrial environments,while in aquatic ecosystems,Sn,Hf,and Au exhibited obvious trophic amplification effects.The calculated average estimated daily intake(EDI)via food consumption in five regions of China was 0.09μg/(kg·day),implying the health risk of aforementioned elements was acceptable.

Concentrations of organophosphate esters in drinking water from the United Kingdom:Implications for human exposure

Data on the presence of organophosphate esters(OPEs)in drinking water and its significance as a pathway of exposure are limited.In this study,we measure for the first time,concentrations of eight OPEs in 50 UK drinking water samples.Arithmetic mean concentrations of ∑8OPEs were:6.4 and 11 ng/L in bottled(n=25)and tap water samples(n=25),respectively.Concentrations of ∑8OPEs in tap water(mean:11 ng/L)exceed significantly those in bottled water(mean:6.4 ng/L)(p˂0.01).Moreover,UK tap water is more contaminated with chlorinated,aryl-,and alkyl-OPEs than bottled water.The predominant OPEs detected were:tris(butoxyethyl)phosphate(TBOEP),tris(2-chloroethyl)phosphate(TCEP),and tris(2-chloroisopropyl)phosphate(TCIPP)with arithmetic mean concentrations in the two water sample types ranging between(3.5e3.8 ng/L),(0.60-3.0 ng/L),and(1.02-2.9 ng/L),respectively.Estimated daily intakes(EDIs)(mean and high-end exposure)via drinking water for different sectors of the UK population were:infants(0.93 and 6.4 ng/kg bw/day)˃toddlers(0.46 and 3.1 ng/kg bw/day)˃children(0.35 and 2.3 ng/kg bw/day)˃adults(0.28 and 2.1 ng/kg bw/day).Based on these data,exposure to ∑8OPEs via drinking water is much lower than via:food,indoor dust ingestion,inhalation,and dermal uptake for adults and toddlers.Reassuringly,our EDIs were lower than relevant reference dose(RfD)values.However,combining our drinking water ingestion data with exposure via other pathways revealed overall exposure to 2-ethylhexyl diphenyl phosphate(EHDPP)and TCIPP to approach health-based limit values for UK toddlers under a high-end exposure scenario.

Differentiated emission control strategy based on comprehensive evaluation of multi-media pollution:Case of mercury emission control

In order to comprehensively evaluate the environmental impact of multi-media mercury pollution under differentiated emission control strategies in China,a literature review and case studies were carried out.Increased human exposure to methylmercury was assessed through the dietary intake of residents in areas surrounding a typical coal-fired power plant and a zinc(Zn)smelter,located either on acid soil with paddy growth in southern China,or on alkaline soil with wheat growth in northern China.Combined with knowledge on speciated mercury in flue gas and the fate of mercury in the wastewater or solid waste of the typical emitters applying different air pollution control devices,a simplified model was developed by estimating the incremental daily intake of methylmercury from both local and global pollution.Results indicated that air pollution control for coal-fired power plants and Zn smelters can greatly reduce health risks from mercury pollution,mainly through a reduction in global methylmercury exposure,but could unfortunately induce local methylmercury exposure by transferring more mercury from flue gas to wastewater or solid waste,then contaminating surrounding soil,and thus increasing dietary intake via crops.Therefore,tightening air emission control is conducive to reducing the comprehensive health risk,while the environmental equity between local and global pollution control should be fully considered.Rice in the south tends to have higher bioconcentration factors than wheat in the north,implying the great importance of strengthening local pollution control in the south,especially for Zn smelters with higher contribution to local pollution.

Characteristics and health risks of population exposure to phthalates via the use of face towels

The production of face towels is growing at an annual rate of about 4%in China,reaching 1.13 million tons by 2021.Phthalates(PAEs)are widely used in textiles,and face towels,as an important household textile,may expose people to PAEs via the skin,further leading to health risks.We collected new face towels and analyzed the distribution characterization of PAEs in them.The changes of PAEs were explored in a face towel use experiment and a simulated laundry experiment.Based on the use of face towels by 24 volunteers,we calculated the estimated daily intake(EDI)and comprehensively assessed the hazard quotient(HQ),hazard index(HI),and dermal cancer risk(DCR)of PAEs exposure in the population.PAEs were present in new face towels at total concentrations of<MDL–2388 ng/g,with a median of 173.2 ng/g,which was a lower contamination level compared with other textiles.PAE contents in used face towels were significantly higher than in new face towels.The concentrations of PAEs in coral velvet were significantly higher than those in cotton.Water washing removed some PAEs,while detergent washing increased the PAE content on face towels.Gender,weight,use time,and material were the main factors affecting EDI.The HQ and HIwere less than 1,which proved PAEs had no significant non-carcinogenic health risks.Among the five target PAEs studied,DEHPwas the only carcinogenic PAE andmay cause potential health risks after long-term exposure.Therefore,we should pay more attention to DEHP.

Health risks associated with heavy metals in the drinking water of Swat,northern Pakistan

The concentrations of heavy metals such as Cd, Cr, Cu, Mn, Ni, Pb and Zn were investigated in drinking water sources （surface and groundwater） collected from Swat valley, Khyber Pakhtunkhwa, Pakistan. The potential health risks of heavy metals to the local population and their possible source apportionment were also studied. Heavy metal concentrations were analysed using atomic absorption spectrometer and compared with permissible limits set by Pakistan Environmental Protection Agency and World Health Organization. The concentrations of Cd, Cr, Ni and Pb were higher than their respective permissible limits, while Cu, Mn and Zn concentrations were observed within their respective limits. Health risk indicators such as chronic daily intake （CDI） and health risk index （HRI） were calculated for adults and children separately. CDIs and HRIs of heavy metals were found in the order of Cr 〉 Mn 〉 Ni 〉 Zn 〉 Cd 〉 Cu 〉 Pb and Cd 〉 Ni 〉 Mn 〉 Cr 〉 Cu 〉 Pb 〉 Zn, respectively. HRIs of selected heavy metals in the drinking water were less than 1, indicating no health risk to the local people. Multivariate and univariate statistical analyses showed that geologic and anthropogenic activities were the possible sources of water contamination with heavy metals in the study area.

A review of sources,fate,levels,toxicity,exposure and transformations of organophosphorus flame-retardants and plasticizers in the environment

Organophosphate esters(OPEs)are esters of phosphoric acid that are increasingly used as plasticizers and by the flame-retardants industries as replacement for the regulated polybrominated diphenyl ethers.The most commonly classes of these pollutants are the chlorinated-and non-chlorinated-OPEs.The extent and magnitude of OPEs occurrence in the environment,combined with striking structural similarities to toxic organophosphorus pesticides has led to public concern over risk posed by these compounds.Using peer-reviewed literature published from the last decade(2010e2019),concentrations and distributions of commonly studied OPEs based on their occurrence in different matrices around the globe were evaluated and reported.These pollutants have a wide range of physicochemical properties such as their water solubility’s,logKow value,vapour pressure and bioconcentration factors(BCFs)which are very important factors in assessing their behaviour in different environmental matrices.Despite progress in research on OPEs over the years,full understanding of the environmental behaviour and fate of these pollutants are still elusive.Sources by which these pollutants enter the environment in conjunction with their concentrations together with their toxicities,estimated daily intakes,transformation products and fates are reviewed.It is envisaged that this review will heighten the importance of identifying emerging issues,data gaps and provide a future research agenda for OPEs.

Metal contents in common edible fish species and evaluation of potential health risks to consumers

Objective:To conduct a health risk assessment of some heavy metals attributed to consumption of common edible fish species available for consumers.Methods:Concentrations of Cd,Cr,Cu,Fe,Mn,Pb and Zn were determined in muscles,gills,livers,bones and skins of six common edible fish species,namely Oreochromis niloticus,Mugil cephalus,Sardinella aurita,Mullus barbatus,Boops boops,Pagrus pagrus.Concentrations of heavy metals were determined by atomic absorption spectrophotometer and expressed asμg/g of wet tissue.Results:Results showed that iron and zinc were the most abundant among all fish tissues under investigation.The data obtained in the present work were compared well with the counterpart data reported internationally.The estimated values of all metals in muscles of fish in this study were below the permissible limits.Moreover,the potential health risks of metals to human via consumption of seafood were assessed by estimating daily intake and target heath quotient.Generally,risk values for the measured metals do not pose unacceptable risks at mean ingestion rate for muscles.Conclusions:It can be concluded that the investigated metals in edible parts of the examined species have no health problems for consumers.
