This study utilized pollution indicators and geographic information system (GIS) to delineate the spatial distribution of heavy metals in the Arak plain. Methods: Dust samples from 30 stations across the Arak plain were systematically collected through random sampling. Analysis using inductively coupled plasma spectrometry (ICP-OES) allowed the calculation of pollution indices (PI) and the Nemerow Integrated Pollution Index (NIPI) for lead (Pb), zinc (Zn), copper (Cu), nickel (Ni), and iron (Fe). GIS generated spatial distribution maps depicting metal pollution. Results: The average concentrations were 45.5 mg/kg for Pb, 10.7 mg/kg for Zn, 0.47 mg/kg for Cu, 30.8 mg/kg for Ni, and 0.206 mg/kg for Fe. Analysis of PI, NIPI, and spatial distribution maps revealed heightened pollution in the northeast, center, south, and southwest areas of the Arak plain, attributed to human activities like heavy vehicle traffic, high population density, concentrated agriculture, and specific industrial operations. Conclusion: The study recommends mitigation strategies, including biological methods like phytoremediation, promotion of public transportation, mandatory environmental standards for industries, and encouragement of green practices. These initiatives aim to address and reduce environmental pollution in the Arak plain.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"87 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140457441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the framework of environmental fate model of ECOFATE, comprehensive data on hydrological sections, input chemical quantities, chemical characteristics, and ecosystem attributes were measured. Results: The findings indicated that lead concentrations were at the highest level in both sediment and water samples of the wetland across three-dimensional space during summer and winter. TSS, TOC and TDS values were estimated, of which the TDS was used to measure ecological risk due to its higher values. Conclusion: The RQ values of lead indicated high and medium risk within the sedimentary and aquatic environments of the wetland ecosystem, respectively. Statistical calculations further revealed that this wetland was at risk of environmental pollution, posing potential hazards to humans through the food chain. The increase in the biological pollution of this wetland is due to the increase in the population and urban sewage.

Methods: A total of 100 water samples were collected from ten sites, including the Dandan water supply station and adjacent residential neighborhoods on the right side of Mosul city between September 2021 and February 2022. Results: The results of the study revealed that the concentration of nitrate ions ranged between (0.95-3.614 mg/L). Based on the study’s results, all of the analyzed water samples fell within the international drinking water quality standards set by the World Health Organization. The concentrations of nitrate ions corresponded to low values of both chronic daily intake (CDI) and hazard quotient (HQ or QI), which ranged from 0.05162 to 0.18164 mg/kg/day and 0.03226 to 0.11357, respectively. Consequently, the hazard index (HI) for this study remained within safe limits for drinking water. The study also revealed that infants and individuals within the age group of 21 and older were the most susceptible to potential nitrate-related health risks, while the age group of 16 to 18 exhibited the lowest susceptibility to such risks. Conclusion: The study recommends the use of examined water for drinking due to its safe and healthy nitrate ion concentration. It further suggests the continuation of periodic assessments of drinking water supply stations to ensure ongoing consumer safety, as no potential health risks, including cancerous and non-cancerous risks, were identified.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"35 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139012500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirteen process-based LCA studies on SWM were reviewed, drawing from established criteria in databases such as SCOPUS, Elsevier, and Google Scholar. These studies were distributed across various African countries, with three conducted in Mauritius and Nigeria each, two in Zimbabwe and South Africa each, and one in Tanzania, Ghana, and Uganda, respectively. The evaluated parameters included aspects such as goal and scope, functional unit, system boundary, impact assessment categories, and sensitivity analysis. The findings revealed that majority of the studies employed similar waste management scenarios to determine the most environment-friendly, yet they differed considerably in some parameters. Climate change and global warming were the most assessed impact categories. Municipal solid waste (MSW) and plastic waste were the leading waste categories. MSW typically comprises paper, bottles, metal, plastics, glass, organics, and mixed waste proportions. The study also stated that the lack of reliable data on solid waste was a significant challenge faced by African countries in LCA studies. The paper’s findings highlighted that a significant number of the studies, particularly in Nigeria, did not incorporate sensitivity analysis into their assessments, a crucial component for result interpretation. Consequently, the study emphasizes the importance of conducting more LCA research studies in African countries to produce pertinent data on SWM.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"70 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139012580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
