Physical, Psychological, and Social Health Impact of Temperature Rise Due to Urban Heat Island Phenomenon and Its Associated Factors

The Urban Heat Island Effect（UHI）has now become a commonly observed phenomenon worldwide.Indeed,it has become a significant environmental effect of urbanisation.In Malaysia,research results showed that UHI effects are very evident in several cities such as Kuala Lumpur and Putrajaya.UHI effect has long been observed to cause temperature of cities.

Economic Valuation of Health Impact of PM_(10) Pollution in Beijing from 2001 to 2006

In light of the practical need for research to inform policy in Beijing,this study evaluates the economic cost of the impact of PM 10 pollution in Beijing from 2001 to 2006,taking health as the main impact,and mortality as the main outcome.Based on the literature review,this study adopts relatively conservative parameters as the basis for calculating the health impacts.It concludes that nearly 30%of mortality among registered residents above age 30 in Beijing can be attributed to PM 10 pollution,and that the economic cost equals 0.8%-1.2%of the city's GDP over the same period.This is lower than the results of previous studies,but still high enough to warrant a commitment to solve the city's air pollution problem.

Assessment of health impacts of noise pollution in the Tarkwa Mining Community of Ghana using noise mapping techniques

Objective Communities in the developing countries such as Ghana have little knowledge of effects of noise pollution on human health,which is demonstrated by their attitude towards this menace.This study assessed the health impacts of noise pollution and its spatial distribution in the Tarkwa Mining Community(TMC)of Ghana.Methods To achieve the study objective,questionnaires were administered;as well as collation of health data from major health centers in the study area.Noise levels were measured and noise map produced using geographic information system(GIS)techniques.Overlay maps of some diseases were done using overlay techniques in GIS.The noise exposure and corresponding noise doses for churches,working sites and social centers were also calculated using the respective formulae.Results The noise levels were found to be high above the prescribed Ghana Environmental Protection Agency(EPA)standards,with traffic noise levels ranging from 65.00 dBA to 98 dBA,while that of churches ranged from 73.10 dBA to 107.00 dBA and that of working sites from 74.4 dBA to 115.2 dBA.The calculated noise exposure and corresponding noise dose for churches ranged from 75.1 dBA to 104.6 dBA(i.e.,10%‒8000%),while that for workers’sites were from 75.8 dBA to 115 dBA(i.e.,12%‒90000%).Statistical regression and correlation analyses were done for diseases such as hypertension,ear problems and sleep disturbances.Conclusion The study has therefore revealed that the noise levels in the study area are very high and corresponding health impacts are prominent.Stakeholders and authorities should devise mitigating measures to combat this rising menace.The results revealed a strong positive correlation between noise and corresponding health impacts.Despite the positive correlation there are other causes and effects to the mentioned diseases.

A Cost-Benefit Evaluation of the Air Quality and Health Impacts in Sao Paulo,Brazil

The objective was to assess the impact on health due to the exposure to air pollution derived from the renewal of the urban bus fleet in S?o Paulo. The study analyzed the substitution of the bus fleet through the variation of the concentration of atmospheric pollutants such as PM10 in the municipality of S?o Paulo and its associated health’s benefits values compared to the investments performed in the bus fleet renewal. PM10 average annual reduction due to the bus improvement system resulted on 22.3%. A cost-benefit evaluation considered the renewal investments’ costs compared to the obtained valued health benefits and it resulted in 4.31. Although the result may suggest a not viable investment, it must be observed that air pollution reduction favors health impacts and that this relation could be improved if additional investments on sustainable transportation increase.

Minimizing Environmental and Health Impacts in Developing Countries through Adoption of Sustainable Energy Options： A Case Study

An extensive review and analysis of the available global energy sources data and information from 38 countries including Pakistan, and their impacts （socio-economic, environmental, and health） shows that one of the most sustainable and environment friendly energy options （especially considering rural areas） is renewable energy （solar and wind）, while other options （in descending order） are hydro, nuclear and coal. The use of ＂oil and gas＂ as energy option is not cost effective due to its serious environmental, health and financial implications. The cost of producing 1 KWh of energy from oil and gas in Pakistan is around Rs. 20 （U.S. $ 0.19）, while the same costs for hydro power and coal are 1/10th and ~nd respectively. Appropriate and suitable energy options are proposed in view of the current energy situation, available natural resources （water, coal, wind and sun）, serious energy conservation efforts and efficient usage of available energy.

A Vietnamese version of the 14-item oral health impact profile (OHIP-14VN)

Aim: To validate a Vietnamese short version (OHIP- 14VN) for use in epidemiological studies. Methods: The original English-language version was translated into Vietnamese, back translated and after some revisions tested for psychometric properties. Subjects (n = 724) were asked to self-administer a questionnaire but could ask for assistance. Convergent validity was tested by investigating associations between OHIP domain and total scores, and dichotomized self-reported satisfaction with 1) the dentition in general, 2) chewing function, and 3) esthetics. Groups validity was evaluated by comparing OHIP scores of subjects having ≤6 molars vs. >6 molars and tooth decay vs. no decay. Test-retest reliability was investigated in a convenience sample (n = 54) and expressed in Intraclass Correlation Coefficients (ICCs). Internal consistency was assessed by Cronbach’s alpha and average interitem correlation coefficients. Results: Validity: all associations were in the hypothesized directions. Differences in mean OHIP total were statistically sig-nificant for all discriminative variables. OHIP scores completed with assistance were significantly lower than those from self-administered questionnaires and therefore analyzed separately. For both administration formats differences in mean scores were still significant for “satisfaction” but for having ≤6 molars or decay the differences lost significance for most domain and total scores. Reliability: ICCs ranged from 0.54 - 0.74. Internal consistency: Cronbach’s alphas for OHIP total scores were 0.93 (self-administered) and 0.91 (with assistance). Average interitem correlation coefficients ranged from 0.26 - 0.67 (self-administered) and 0.28 - 0.69 (with assistance). Conclusions: This Vietnamese version of the OHIP-14 demonstrated good construct validity and acceptable reliability for OHIP total scores however OHIP-14VN domain scores should be interpreted with caution.

Uncovering the impact of alcohol on internal organs and reproductive health:Exploring TLR4/NF-kB and CYP2E1/ROS/Nrf2 pathways

This review delves into the detrimental impact of alcohol consumption on internal organs and reproductive health,elucidating the underlying mechanisms involving the Toll-like receptor 4(TLR4)/Nuclear factor kappa light chain enhancer of activated B cells(NF-kB)pathway and the Cytochrome P4502E1(CYP2E1)/reactive oxygen spe-cies(ROS)/nuclear factor erythroid 2-related factor 2(Nrf2)pathways.The TLR4/NF-kB pathway,crucial for inflammatory and immune responses,triggers the production of pro-inflammatory agents and type-1 interferon,disrupting the balance between inflammatory and antioxidant responses when tissues are chronically exposed to al-cohol.Alcohol-induced dysbiosis in gut microbes heightens gut wall permeability to pathogen-associated molecular patterns(PAMPs),leading to liver cell infection and subsequent inflammation.Concurrently,CYP2E1-mediated alcohol metabolism gen-erates ROS,causing oxidative stress and damaging cells,lipids,proteins,and deoxy-ribonucleic acid(DNA).To counteract this inflammatory imbalance,Nrf2 regulates gene expression,inhibiting inflammatory progression and promoting antioxidant re-sponses.Excessive alcohol intake results in elevated liver enzymes(ADH,CYP2E1,and catalase),ROS,NADH,acetaldehyde,and acetate,leading to damage in vital organs such as the heart,brain,and lungs.Moreover,alcohol negatively affects reproduc-tive health by inhibiting the hypothalamic-pituitary-gonadal axis,causing infertility in both men and women.These findings underscore the profound health concerns associated with alcohol-induced damage,emphasizing the need for public awareness regarding the intricate interplay between immune responses and the multi-organ im-pacts of alcohol consumption.

Impact of Plastic Waste on the Human Health in Low-Income Countries: A Systematic Review

Background: Plastic pollution is the accumulation of waste composed of plastic and its derivatives all over the environment. Whether in the form of visible garbage or microparticles, as it slowly degrades, plastic pollution poses significant threats to terrestrial and aquatic habitats and the wildlife that call them home, whether through ingestion, entanglement or exposure to the chemicals contained in the material. Unfortunately, there is a lack of documentation on the impact of plastic waste on human health in low- and middle-income countries (LMICs). Methods: We searched five electronic databases (PubMed, Embase, Global Health, CINAHL and Web of Science) and gray literature, following the preferred reporting elements for systematic reviews and meta-analyses (PRISMA), for the impact of plastic waste on human health in developing countries. We included quantitative and qualitative studies written in English and French. We assessed the quality of the included articles using the Mixed Methods Appraisal tool (MMAT). Results: A total of 3779 articles were initially identified by searching electronic databases. After eliminating duplicates, 3167 articles were reviewed based on title and abstract, and 26 were selected for full-text review. Only three articles were retained. The three articles dealt with practices likely to lead to oral exposure to plastic chemicals in human health, as well as the level of awareness of participants concerning the possible impact of plastic on human health, namely, the use of plastic baby bottles, the use of microwaves to cook food and reheat precooked food, the use of plastic bottles to store water in the refrigerator, water purifier containers with plastic bodies and plastic lunch boxes, the reuse of plastic bags and the inadequacy of treatment facilities. Conclusion: Plastic waste poses different risks to human health at every stage of its life cycle. Hence, strategies must be adopted to raise public awareness of the dangers of plastic waste to their health. Trial registration: The review protocol is registered in the PROSPERO international prospective register of systematic reviews (ID = CRD42023409087).

Influence of Exposure Pathways on Tissue Distribution and Health Impact of Polycyclic Aromatic Hydrocarbon Derivatives

The oxygen(OPAHs),nitro(NPAHs),hydroxyl(OH-PAHs),and alkylated(APAHs)derivatives of polycyclic aromatic hydrocarbon(PAHs)are ubiquitous pollutants in the environment.The concentrations of NPAHs,OPAHs,OH-PAHs,and APAHs are lower than that of PAHs in the environment,but the carcinogenic abilities of the derivatives are usually 10 to 1,000-fold higher than that of parent PAHs.There are three main pathways for the exposure of polycyclic aromatic compounds to humans,including inhalation,direct contact,and ingestion.After exposure by inhalation,they are mainly distributed in the lungs,affecting lung function and causing inflammation,asthma,etc.Due to the digestive system’s strong capacity for metabolism,intake of PAHs and the derivatives is primarily distributed in the digestive system and metabolized there.And it may lead to dysplasia of these organs and even to cancer.The skin is the primary site of direct contact with PAH derivatives.PAH derivatives can enter the bloodstream through all three contact pathways,thereby accumulating in various organs.This study aimed to summarize the influence of exposure pathways on tissue distribution and the health impact of PAH derivatives to provide references for future research and evaluation on public health.

Planetary health risks in urban agriculture

Urban agriculture is gaining recognition for its potential contributions to environmental resilience and climate change adaptation,providing advantages such as urban greening,reduced heat island effects,and decreased air pollution.Moreover,it indirectly supports communities during weather events and natural disasters,ensuring food security and fostering community cohesion.However,concerns about planetary health risks persist in highly urbanized and climate-affected areas.Employing electronic databases such as Web of Science and PubMed and adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines,we identified 55 relevant papers to comprehend the planetary health risks associated with urban agriculture,The literature review identified five distinct health risks related to urban agriculture:(1)trace metal risks in urban farms;(2)health risks associated with wastewater irrigation;(3)zoonotic risks;(4)other health risks;and(5)social and economic risks.The study highlights that urban agriculture,while emphasizing environmental benefits,particularly raises concerns about trace metal bioaccumulation in soil and vegetables,posing health risks for populations.Other well studied risks included wastewater irrigation and backyard livestock farming.The main limitations in the available literature were in studying infectious diseases and antibiotic resistance associated with urban agriculture.

Atmospheric Pollutants in a Commercial Region of Fortaleza, Ceará, Brazil: Integration of Health, Environment and Economy in Urban Planning to Improve Air Quality

The accelerated growth of the vehicular fleet, the modernization of large urban centers, and the few adjustments to the road network in Fortaleza have intensified the problems of traffic and emissions of atmospheric pollutants, highlighting the necessity for strategic urban planning initiatives to address the escalating issues of traffic and pollution. With the objective of analyzing the indices of concentrations of atmospheric pollutants and estimating how these levels can affect human health, this work consists of a study of the analysis of air quality in the intense trade region of Fortaleza. For this, the analysis zone was divided into three perimeters (Major - Medium - Minor), where each perimeter was analyzed at 7 am, 12 noon and 5 pm. Concentrations of the type of O3, particulate matter (PM2.5 and PM10), CO2 and HCHO were collected. Our results demonstrate that most of the analyses are within the limits of current legislation;however, at certain times and perimeters, the analyses of CO2 and HCHO exceeded the established limits. In view of the above, we conclude that public policies to control air quality are necessary to reduce the damage to human health and the environment caused by pollutants.

Assessing the Impact of Health Insurance on Household Financial Protection in Togo

Context: To facilitate financial access to care for the population, health insurance mechanisms have been established, in particular the National Health Insurance Institute, which covers civil servants and their dependents. In addition, other voluntary and community mechanisms have been developed. After several years of implementation, the level of catastrophic health expenditures among insured individuals shows that there is still a considerable level of financial risk associated with health care. This study aims to assess the impact of health insurance in Togo on insured populations. Methodology: The data used in this study come from the harmonized survey on household living conditions carried out in 2018 by the National Institute of Statistics, Economic and Demographic Studies. The propensity score matching method was used according to the following steps: estimation of propensity scores, verification of the conditional independence hypothesis (balancing property) and estimation of the average treatment effect on treated. Stata V14.2 software was used. Findings: The average effect of health insurance on household financial protection is −0.012 for the nearest neighbor method, −0.013 for the matching radius method, −0.015 for the Kernel and −0.016 for the stratification method. Results showed that health insurance contributes to reducing catastrophic health expenditures, but their effect remains very limited. This could be explained by the level of care package covered and the cost covered. Conclusion: Health insurance contributes to the reduction of catastrophic health expenses for households. However, it is important to widen the range of care covered and the cost covered. In addition, measures to extend this coverage to a larger proportion of the population will make it possible to have a greater impact.

Understand the local and regional contributions on air pollution from the view of human health impacts

The source-receptor matrix of PM_(2.5)concentration from local and regional sources in the Beijing-Tianjin-Hebei(BTH)and surrounding provinces has been created in previous studies.However,because the spatial distribution of concentration does not necessarily match with that of the population,such concentration-based source-receptor matrix may not fully reflect the importance of pollutant control effectiveness in reducing the PM_(2.5)-related health impacts.To demonstrate that,we study the source-receptor matrix of the PM_(2.5)-related deaths instead,with inclusion of the spatial correlations between the concentrations and the population.The advanced source apportionment numerical model combined with the integrated exposure-response functions is used for BTH and surrounding regions in 2017.We observed that the relative contribution to PM_(2.5)-related deaths of local emissions was 0.75%to 20.77%larger than that of PM_(2.5)concentrations.Such results address the importance of local emissions control for reducing health impacts of PM_(2.5)particularly for local residents.Contribution of regional transport to PM_(2.5)-related deaths in rural area was 22%larger than that in urban area due to the spatial pattern of regional transport which was more related to the rural population.This resulted in an environmental inequality in the sense that people staying in rural area with access to less educational resources are subjected to higher impacts from regional transport as compared with their more resourceful and knowledgeable urban compatriots.An unexpected benefit from the multi-regional joint controls is suggested for its effectiveness in reducing the regional transport of PM_(2.5)pollution thus mitigating the associated environmental inequality.

Experience and lessons from health impact assessment guiding prevention and control of HIV/AIDS in a copper mine project,northwestern Zambia

Background:To avoid or mitigate potential project-related adverse health effects,the Trident copper project in Kalumbila,northwestern Zambia,commissioned a health impact assessment.HIV was identified a priority health issue based on the local vulnerability to HIV transmission and experience from other mining projects in Africa.Hence,an HIV/AIDS management plan was developed,including community and workplace interventions,with HIV testing and counselling(HTC)being one of the key components.We present trends in HTC data over a 4-year period.Methods:In 13 communities affected by the Trident project,HTC was implemented from 2012 onwards,using rapid diagnostic tests,accompanied by pre-and post-test counselling through trained personnel.In addition,HTC was initiated in the project workforce in 2013,coinciding with the launch of the mine development.HTC uptake and HIV positivity rates were assessed in the study population and linked to demographic factors using regression analysis.Results:In total,11,638 community members and 5564 workers have taken up HTC with an increase over time.The HIV positivity rate in the community was 3.0%in 2012 and 3.4%in 2015,while positivity rate in the workforce was 5.2%in 2013 and 4.3%in 2015.Females showed a significantly higher odds of having a positive test result than males(odds ratio(OR)=1.96,95%confidence interval(CI):1.55-2.50 among women in the community and OR=2.90,95%CI:1.74-4.84 among women in the workforce).HTC users in the 35-49 years age group were most affected by HIV,with an average positivity rate of 6.6%in the community sample and 7.9%in the workforce sample.These study groups had 4.50 and 4.95 higher odds of being positive,respectively,compared to their younger counterparts(15-24 years).Conclusions:While HTC uptake increased five-fold in the community and almost three-fold in the workplace,the HIV positivity rates were insignificantly higher in 2015 compared to 2012.Our data can be used alongside other surveillance data to track HIV transmission in this specific context.Guided by the health impact assessment,the HIV prevention and control programme was readily adapted to the current setting through the identification of socioeconomic and environmental determinants of health.

Impact of Ambient Air Pollution on Public Health under Various Traffic Policies in Shanghai,China

Objective To investigate the potential impact of ambient air pollution on public health under various traffic policies in Shanghai. Methods The exposure level of Shanghai residents to air pollution under various planned traffic scenarios was estimated, and the public health impact was assessed using concentration-response functions derived from available epidemiological studies. Results Our results showed that ambient air pollution in relation to traffic scenarios had a significant impact on the future health status of Shanghai residents. Compared with the base case scenario, implementation of various traffic scenarios could prevent 759-1574, 1885-2420, and 2277-2650 PM10-related avoidable deaths （mean-value） in 2010, 2015, and 2020, respectively. It could also decrease the incidence of several relevant diseases. Conclusion Our findings emphasize the need to consider air pollution-related health effects as an important impact of traffic policy in Shanghai.

Quantitative Health Impact Assessment for Urban Planning Schemes

Health impact assessment (HIA) is an approach to identification of potential health benefits or hazards in urban planning schemes.Quantitative HIA provides uniform and comparable health outcomes (e.g.,the morbidity of a specific disease),which could effectively assist planning decisions.However,there are currently few quantitative HIA methods specifically for urban planning applications.Based on a review of existing HIA methods,this paper has developed a quantitative HIA system for urban planning schemes in China,and specifically evaluates health risks,health behaviors,and health outcomes.Taking the Territorial and Spatial Master Plan of the Gucun Township of Shanghai as an example,we have illustrated how to evaluate the reduced health risks and increased health behaviors,as well as how to calculate changes in potential health outcomes in order to provide a reference for relevant HIA practices.

Monitoring of the Physicochemical and Bacteriological Quality of the Water of the Gounti-Yéna Basin and Assessment of the Impact on the Health of the Populations

The Gounti Yéna valley is the main watercourse that divides the left bank of the city of Niamey into two unequal parts. The area of its watershed is estimated at about 62 km2. The objective of this study is on the one hand to evaluate the current state of the physico-chemical and bacteriological quality of the water of the Gounti Yéna basin and on the other hand to define the risks of water pollution and its origin in the face of the phenomenon of the rise in the water table of this basin by defining some health risks linked to these impacts. In order to properly carry out this work, we carried out a study of the evolution of the physicochemical and bacteriological parameters of the water of the Gounti Yéna basin during the period from November 2020 to October 2021, at three sampling points chosen from upstream to downstream of the basin then entomological surveys and among the health centers of the capital. The results obtained showed that the physico-chemical quality of water in the Gounti Yéna basin is influenced by climatic factors (precipitation and temperature) and anthropogenic actions. This study also highlighted the presence of faecal contamination in the water of the Gounti Yéna basin with a greater degree during the rainy season. This contamination remains worrying and constitutes a health risk causing waterborne diseases. The stagnation of the various bodies of water is also a favorable place for the development and spread of vector-borne diseases.

Carbon Dioxide Emissions by the Transportation Sector and Its Impact on Health in the Kathmandu Valley, Nepal

Air pollution is one of the leading cause of death for underdeveloped as well as developed countries. In 2011, the air pollution was the second leading cause of death in one of the main hospitals of the Kathmandu Valley, Nepal, and it was the third leading cause in the United States. Burning fossil fuels for transportation was one of the major causes. Among various impacts of the air pollution, COPD （chronic obstructive pulmonary disease） was one of the main consequences. In the 570 km2 Kathmandu Valley, vehicle registration was increased from 45,871 in 1990/1991 to 570,145 in 2010/2011, an increase of over 12-fold over 20 years. The vehicle registration and number of COPD patients＇ data were collected from various government divisions. In addition, the average daily travel distance and fuel mileage data were collected with a survey with residents of the Kathmandu Valley. This paper calculates the amount of carbon dioxide （CO2） emissions by transportation sector and determines correlation between CO2 emissions and COPD patients. Results show that there was a very high level of CO2 emissions, and it was positively correlated with the number of COPD patients in the valley.
