Methods: Statistical population of this analytical, cross-sectional survey was 31 health, safety, and environment (HSE) experts from the study refinery selected by purposeful sampling. Environmental, health, safety, and technical risks were categorized and identified using the PMBOK guidelines. Delphi method and 5-point Likert scale questionnaire were employed to assess the significance of each risk. Priority one risks within each category were determined using Primavera Risk Analysis version 8.7 software. Results: Following three Delphi steps, 17 out of 77 primary risks were identified and finalized. The first rank with the highest weight corresponded to time and cost group (the risk of soil contamination via sludge stored in the burn pit due to aliphatic and aromatic hydrocarbons), human resources group (radioactive materials accumulated on the inner surfaces of pipes, valves, pumps, heat exchangers, tanks, boilers and other equipment and the risk of these materials being hazardous for human health), and quality group (failure to supply equipment and quality control systems and personal protective equipment). Conclusion: The research findings pinpointed 17 risks within various domains, encompassing time and cost, human resources, quality, contract, scope, and communication. These identified risks necessitate a comprehensive, integrated approach to risk management for effective mitigation and resolution.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"132 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139012701","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}

Methods: In this study, the effect of PS/Fe2+/UV on tetracycline and amoxicillin removal was investigated. Different parameters including pH, different concentrations of iron, antibiotics and persulfate were investigated for removal efficiency. The remaining concentration of the solution was measured using a high performance liquid chromatography (HPLC) device. The degree of mineralization of the process was evaluated using the chemical oxygen demand (COD) parameter. Then, the removal of tetracycline, amoxicillin and COD from the pre-treated wastewater in the batch biological reactor was investigated. Results: The results demonstrate that the PS/Fe2+/UV process achieved complete removal of tetracycline and 97.3% removal of amoxicillin under laboratory conditions. In wastewater treatment, the process achieved a 69% reduction in tetracycline and a 67.2% reduction in amoxicillin within a 60-minute reaction time. Also, the amount of mineralization of tetracycline and amoxicillin antibiotics by PS/Fe2+/UV process was evaluated using COD index, which resulted in removal of more than 60% of COD for both antibiotics. Also, the combination of this process and the batch biological reactor succeeded in removing 99% of BOD5 from both antibiotics and 98% of COD from real wastewater, containing 10 mg of tetracycline and amoxicillin. Conclusion: The combined PS/Fe2+/UV process and batch biological reactor is an efficient method. It is effective for removing antibiotics and its mineralization for wastewater treatment containing tetracycline and amoxicillin antibiotics.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"25 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139012668","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 research into plasmids as potential carriers for transferring new resistance genes among clinical pathogens has been quite constrained. This study was conducted to determine the extent of multidrug resistance and the presence of plasmids in E. coli and S. aureus isolates derived from wastewater effluents at healthcare institutions in Lafia, Nigeria. Methods: A total of 231 effluent samples were collected from different units within the healthcare facilities and bacterial identification performed using standard CLSI identification techniques. Phenotypic multidrug resistance was analyzed using the Kirby-Bauer disc diffusion method while plasmid DNA was extracted by alkaline lysis and separated using 0.8% agarose gel electrophoresis. Results: A total of 167 (72.3%) and 175 (75.6%) samples were positive for E. coli and S. aureus, respectively. Both E. coli and S. aureus exhibited the greatest resistance to amoxicillin, with resistance rates of 79.0% and 66.3%, respectively. Conversely, the lowest resistance was observed for levofloxacin (26.3%) and cotrimoxazole (25.1%) in E. coli and S. aureus, respectively. The study did not find any significant correlation between the phenotypic antibiotic resistance profiles of the isolates and different wastewater discharge points (P>0.05). Out of the total isolates, 77 (46.1%) of E. coli and 51 (29.1%) of S. aureus were resistant to all tested antibiotics. A majority of these isolates exhibited multiple antibiotic resistance index (MARI) values greater than 0.5, with 87.4% of E. coli and 80.6% of S. aureus demonstrating multidrug resistance. Plasmid analysis for E. coli indicated that the largest proportion of the selected isolates (46.7%) carried double plasmids with sizes ranging from 1500 to 6000 base pairs (bp), and 6.7% had no plasmids. In the case of S. aureus, 53.3% of the isolates harbored a single plasmid with a size of 7500 bp, while 46.7% had no plasmids.

The Zayande-rood’s dam lake is one of the vital water resources that provide drinking water for the populations in Isfahan. It is also a water resource for agricultural sections of the province. Methods: Five spots were defined as the sampling stations. Sampling was conducted in seven steps, with one sampling event every 45 days. The water quality parameters including dissolved oxygen (DO), nitrate, nitrite, electrical conductivity (EC), pH, hardness, total dissolved solids (TDS), ammonium, and biochemical oxygen demand (BOD) were measured in all the stations and stages. Next, the water quality indices were calculated. Results: The study’s results illustrated that the water quality, with an average score of 74.41 on the water quality index (WQI), fell within the ‘well’ class, indicating its suitability for human consumption and drinking purposes. Station 4 scored the highest NSFWQIa (74.93), while station 3 had the lowest (70.57). According to the NSFWQI classification, all stations are categorized as ‘good’ in terms of water quality. The NSFWQIm ranged from 50.94 to 59.04, showing moderate changes in water quality. Both the NSFWQIa and NSFWQIm classify it as ‘moderate’ or ‘midclass’ quality. Conclusion: Considering the significance of Zayande-rood’s dam lake as a crucial source of drinkable water for Isfahan, it becomes evident that there is a pressing need for significant attention to be directed toward lake watershed management to protect water quality.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"40 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139012682","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 assessment focuses on the inhalation exposure route to workplace emissions. Methods: The primary locations for potential pollutant emissions were identified in close proximity to the areas where chemicals were introduced and utilized within the production process. Sulfuric acid, sodium hydroxide, ammonia, oil mist, toluene, hydrogen sulfide, hydrazine, and tetrachloromethane were measured and analyzed using the NIOSH standard. Dose-response assessment was estimated using inhalation unit risk (IUR) for cancer risks and reference concentration (RFC) and reference exposure levels (REL) for non-cancer risks. Risk assessment was performed based on the Environmental Health Hazard Assessment guideline. Results: The results showed that ammonia and toluene had the highest and lowest concentration of pollutants emitted in workplace, respectively. The inhalation of ammonia and sulfuric acid and their daily absorption were at high risk level (HQ>1). Other noncancerous compounds had HQ<1. While the hazard index (HI) for total non-cancer risks was 5.34E+01 (HI>1), it was likely to have non-cancerous risks. For carcinogenic risks, they were calculated to be 9.58E-03 and 5.47E-04 for hydrazine and tetrachloromethane, respectively. The total carcinogenic risk of the emissions was calculated at 1.01E-02, which was in the significant range (more than 10-4) (i.e. in the range of hazardous cancer effects).

In this regard, calculation of the equivalent particle diameter (EPD) is of important to determine the particle Reynolds number (Ret ) as well as total load calculation. Methods: In this research work, 5 different particle diameters (i.e. d35, d50, d65, dm and deff) have been used in three famous total load calculation methods for calculating the best EPD. For this goal, a field experimental data has been collected at the entrance grit chamber of wastewater treatment plant (WWTP) of Khomein city, Iran. The total load of the sediments has been measured and the results compared with the total loads calculated by the three famous total load computation methods (i.e. Graf & Acaroglu method, Laursen method and Yang & Lim method) by using the particle diameters. Results: The results show that the methods estimate the total load of sediments with the relative errors of 4.25, 10.80 and 1.26 by using dm, d35 and d65 as the EPDs, respectively. Also, a simplified and improved correction factor has been developed and the results show that by applying the correction factor the relative errors of the methods decrease and they are equal to 10.34, 3.45 and 496.5, respectively. The improvement of the mentioned total load methods is equal to are 82.70%, 93.10% and 34.80%, respectively.

In this study, we conducted an analysis of the environmental impact associated with generating 1 kilowatt-hour of electricity in a combined-cycle power plant located in the southwest region of Iran. Methods: An LCA following ISO 14044 standards was conducted via the ReCiPe method evaluating 10 impact categories at the midpoint level, and covering the entire life cycle. This method was selected for its comprehensive modeling of potential impacts from numerous chemicals and its practicality at both midpoint and endpoint levels. Results: The study found that resource availability (RA) has the highest impact at 53% in endpoint categories, mainly due to natural land transformation (NLT) and fuel depletion (FD). Human health (HH) contributes 43%, while ecosystem diversity (ED) has a minor 4% role. In midpoint categories, over 99% of global warming potential (GWP) and climate change (CC) are from CO2 emissions due to fossil fuel combustion. Conclusion: Midpoint analysis identified NLT, FD, CC, freshwater ecotoxicity, terrestrial ecotoxicity, human toxicity, photochemical oxidant formation, terrestrial acidification, freshwater eutrophication, and water depletion as the most impacted categories by the power plant.

This review has used different databases in Iran and Iranian studies in other international databases. Studies that did not investigate the characteristics of water were excluded, and the studies passed the quality criteria of this review as well as its data were analyzed. The studies showed that the average concentration of water parameters such as total hardness, alkalinity, dissolved oxygen, sulfate, and nitrate in the output water of these devices had decreased. Also, residual chlorine in the outlet water of all samples was lower than the standard value. To use household water purification devices, in addition to considering the benefits of using these devices, we should also pay attention to the reduction of physicochemical and microbiological quality of water.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"80 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334690","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}
