This method also helps reduce aquifer depletion, mitigate land subsidence, and enhance groundwater quality. Methods: In this study, artificial feeding methods were used to determine the appropriate location for the Ghaemshahr plain. Water resources were tested in terms of quantity and quality through field and laboratory studies. Based on the findings, geographic information system (GIS) mapping was utilized to create maps and select the best location and feeding method. Results: The most important source of nutrition for recharging the aquifer in terms of quantity and quality was the Talar River. The study area’s conditions like aquifer thickness, permeability, topographic slope, and land use were analyzed using GIS and thematic maps. The results indicated that by using these methods, it is possible to store 5 million cubic meters of surface water in the aquifer for 6 months. Conclusion: This study demonstrated the feasibility of using surface waters in the area for artificial feeding, employing the pond method1. Additionally, it is recommended to dig measuring wells to monitor the water level rise at the bottom of the pond 1. It also suggests the use of simulation software like PMVIN, Mod flow, and GMS to optimize the artificial replenishment process and select the most suitable approach from the defined scenarios before taking any actions.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334143","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}

Hence, this study aimed to assess the level of environmental pollution in urban areas in terms of litter density. Methods: The quantity of littered wastes (LWs) was examined across six residential areas, with observations and waste counting conducted over a two-month period on both working days and weekends. The LWs were categorized into four groups, and their on-site density was calculated. Results: The results indicated that the average waste density in the locations studied was 5.08 number/m2 . The lowest recorded LW number was 19.49 number/100 m, while the highest was 30.49 number/100 m. The categories of plastic and tobacco wastes comprised 13.25% and 82.64% of the total LWs, respectively. On average, 0.71 number/100 m of paper were observed in the areas studied, accounting for 2.8% of the total LWs. The presence of suitable waste bins in the areas surveyed underscores the significant influence of individual behavior on urban pollution. Conclusion: Therefore, there is a pressing need to raise awareness among citizens regarding the consequences of littering and to implement more effective urban cleanup methods.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334169","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}

These methods are effective alternatives to traditional elimination methods. Methods: Bacillus cereus PTCC 1015S strain was used to eliminate acid blue 113 (AB113) and acid orange 7 (AO7) from aqueous solutions. The bacteria were activated in the Luria Bertani Broth (MILLER) culture medium. The effective parameters such as incubation time and temperature, pH of dye solution, dye concentration, and the bacterial inoculation quantity on decolorization were investigated. Kinetic and thermodynamic studies were done to clarify the different aspects of the introduced method. Also, the reliability of the method to remove studied dyes was investigated in dye factory wastewater samples. Results: The first-order kinetic model was the best model to describe the kinetics of decolorization. The obtained thermodynamic data showed that the elimination process was endothermic (∆H0=+29.03, 30.53) while it was spontaneous (∆G0<0) for both studied dyes and so entropy change (∆S0=+109.63, 116.32) was an effective force in the decolorization. Under optimized conditions, B. cereus PTCC 1015S showed high average removal; 98.5 and 99.3 % for AB113 and AO7 respectively in dye model solutions. The removal efficiency was more than 85 % for both studied dyes in wastewater spiked samples. Conclusions: The B. cereus PTCC 1015 strain was capable of being exploited in the removal of AB113 and AO7 dye molecules as an affordable and eco-amiable method for the treatment of aqueous samples contaminated with the studied azo dyes.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"282 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334707","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}

Since the qanat water is currently used in some parts of Iran for drinking and agricultural purposes, its quality management is of great importance. This study aimed to evaluate the water quality of the qanat in the eastern areas of Tehran. Methods: Water sampling was performed in eight qanats in the east of Tehran in triplicate (mother well and one of the access shafts and outlet) during the summer of 2020. The measured parameters were pH, total dissolved solids (TDS), electrical conductivity (EC), CO3 2-, HCO3 - , Na2+, Ca2+, Mg2+, K+, Cl- , NO3 , SO4 2-, total hardness (TH) and total alkalinity (TA). The quality was assessed according to the standards introduced by the World Health Organization (WHO) and Food and Agriculture Organization. Groundwater quality index (GWQI) was used to classify the samples. Results: The lowest (56.05) and the highest (2058.58) GWQI scores corresponded to qanats 5 (Elimon) and 8 (Aminabad) with good and very poor quality, respectively. There was a decrease in the water quality of qanats 8 (Aminabad), 7 (Sulaymaniyah), 6 (Mehdiabad) and 2 (Majidieh), respectively. Conclusion: The quality of the qanats were in the range of good to very poor. The reasons for difference in water quality could be due to the direction of anthropological pollutants and geological structures. To control the water quality of the qanats in the east of Tehran, the quality monitoring network is recommended to be designed for various pollutants and optimized for long term.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139358868","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}

In the industries, there is a wide range of flammable and toxic substances that affect health and safety of workers. They have also adverse effects on society. Numerical risk and impact assessment as well as design for protective layers against catastrophic events are necessary for designing process units. Methods: First, the occupational-process and environmental safety hazards were measured by hazard and operability (HAZOP) and environmental failure mode and effects analysis (EFMEA) techniques. Then, the risk was assessed using the layer and operability analysis (LOPA) method. Results: The results showed that a total of 50 safe and health items and 37 environmental risks were identified by HAZOP and EFMEA methods in Imam Khomeini Petrochemical Aromatic Unit. There were 17, 19 and 14 items with low, medium and high level risk, respectively. Conclusion: This study showed that the LOPA method is more comprehensive than hazard identification methods for the analysis of protective layers. The important actions were blockage of the excess gas to the flare and release the H2S gas. Also, evaluation of the environmental aspects of aromatic unit activities showed that air pollutant production in the power supply unit, waste disposal of reactor tank, waste disposal of condensate tank and reactor fire and explosion were at a high level risk.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139358956","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}
