This study estimated the lifetime cancer risk (LCR) attributable to BD in District 9 of Tehran Municipality and simulation of its releasing way. Methods: This research is an applied study that was conducted in the form of field research. Cancer risk assessment was carried out based on the United States Environmental Protection Agency (USEPA) method. BD concentration measurements were performed at 30 points and specified in the area and daily at three different times in four seasons since autumn of 2019 till summer of 2020. LCR then was calculated for four different groups of residents, employees, first and second classes of the pedestrian. Finally, the way of releasing BD in the District 9 was evaluated by GIS software. Results: The results showed that the highest and lowest BD concentrations were 2819 and 424 ppb, respectively, in autumn and spring. They were measured in the north and west side of the District 9 which were much higher than inhalation reference concentration. In addition, the LCR estimation of population due to exposure to high level of BD was exceeded the USEPA benchmark of 1×10-6 in the 4 specified groups. So, the amount of LCR in the residents was 790 times more than the USEPA benchmark. Conclusion: According to the results, the necessity for traffic control by urban management and producing green vehicles to prevent pollutants emission is essential.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79237297","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}

Given the water resources restriction, it is crucial to manage these resources properly, recognize the current situation, and anticipate the harvesting or feeding effects. In this regard, simulators or models can act as valuable tools. Methods: In this research, we performed quantitative modeling of groundwater flow in the Quar-Maharlu plain, Fars Province, Iran using the PMWIN software. The model included three years’ calibration (2011-2014) for hydraulic conductivity coefficient and one year’s verification (2014-2015). To evaluate the model error in calibration and verification, the root mean square deviation (RMSD) was used. After simulating the aquifer to optimize the artificial recharge location by the flood spreading method, different scenarios were defined and examined by considering the natural and artificial factors. Results: The RMSD values for calibration were 1.55, 1.49, and 1.56 m for 2011, 2012, and 2013, respectively. The RMSD for verification of one year was 1.77 m, indicating the acceptable ability of the model to predict groundwater flow parameters. The stock variation for the whole aquifer was -8.88 mm3 in 2014. In the next step, the best recharging location was selected to create the maximum head increase (5.3cm) in the entire area of the plain. Conclusion: One of the effective ways to offset the negative balance is to strengthen the aquifer through artificial recharge.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87926048","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}

The purpose of this paper was to locate the industries of Kashan City and rank the appropriate alternatives using analytic hierarchical process (AHP) and the prioritization methods of fuzzy VIKOR and fuzzy TOPSIS. Methods: In this study, first, the effective criteria in GIS (Geographic Information System) were examined and standardized according to fuzzy logic. Then, by presenting expert opinion through AHP, the criteria were weighted, and in order to determine suitable places for establishing industries, according to the required minimum area, six alternatives were extracted from the weighted linear combination method. Subsequently, the alternatives were ranked using fuzzy VIKOR and fuzzy TOPSIS methods. The sensitivity analysis was performed in the fuzzy TOPSIS method by shifting the criteria weights and producing different weighting scenarios. The fuzzy VIKOR method was analyzed for different values of the υ variable. Results: Weighting of criteria by AHP showed that the distance from surface water with a weight coefficient of 0.200 was the most important one. according to the required minimum area, six alternatives were extracted from the weighted linear combination method.

The use of zeolite is one of the solutions in soil pollution management. The aim of this study was to investigate the impact of natural zeolite on grain protein, Mg and Zn uptake in the wheat in contaminated soils by war weapons. Methods: The experiment was carried out in factorial arrangement in a randomized complete design with three replications in a pot. The studied treatments were four levels of zeolite as zero, 0.5, 1.5 and 2.5% based on weight of soil and two types of soils including non-contaminated and contaminated soil by mines and war explosives. Contaminated and non-contaminated soil samples were taken from the southern region of Dehloran city. Results: The results showed that the amount of grain protein and Mg in contaminated soils were significantly higher than non-contaminated soils. The use of zeolite in both soils caused a significant increase in either of them. In this study, the Zn concentration of grain in contaminated soils was higher than non-contaminated. In addition, the concentration of Zn was significantly decreased when zeolite consumption was increased. Conclusion: The results showed that the use of zeolite in contaminated and non-contaminated soils had a positive effect in terms of grain protein and Mg. In addition, the use of zeolite can prevent the excessive increase in Zn due to war weapons and can be effective in plant and community health.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"68 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79130085","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}

Lead (Pb) is known as a very toxic and non-biodegradable element that has no metabolic function in living creatures. It can be easily taken up and transferred within plant tissues; consequently, it can easily enter the food chain, causing phytotoxicity, which in turn through different biochemical and enzymatic reactions, can result in severe threats to public health. After entering soil and sediments, Pb may be diffused among soil components and associated with them through different geochemical fractions, which determine the final fate of Pb in terms of bioavailability and uptake by plants. Metal bioavailability in soils is largely dependent on the soil and plant properties and interactions with other elements. In spite of the fact that there are numerous studies on the influence of heavy metals on public health but there are limited studies that consider the role of the soil-plant chain on the final fate of potentially toxic metals in respect to threat the public health.

However, an important challenge is its environmental constraints. Methods: In this study, the effect of vermifiltration on properties of sewage influent was investigated. The sewage influent was obtained from the aerated lagoons of Qahdarijan wastewater treatment plant, Isfahan, Iran. It was mixed with rice husk (RH) and wheat straw (WS) as the bulking agents in three levels (0, 5 and 10%v/v). Earthworm (Eisenia foetida) was added to the sewage sludge in 2 levels [0 (EW0) and 50 (EW) adult earthworms /6 kg sewage sludge]. Results: The results showed a significant decrease in EC (about 100% decrease compared to the control), TDS (up to 3 times in RH0+ EW treatment less than the control), TSS (up to 90 times in WS10+EW and RH +EW treatments decrease compared to the control), biochemical oxygen demand (significant decrease in RH levels + EW compared to other treatments), chemical oxygen demand (a reverse status was observed for WS and RH treatments but the role of vermifiltration was considerable). The concentration of Pb was significantly decreased in WS when was enriched with earthworms (about 8% decrease compared to control) but a reverse status was observed for RS treatment.
