It was determined that the main cause of the radioactive pollution in the area is not limited to the effects of radioactive isotopes of natural origin rather it takes place also due to the contamination of oilfields driven by technogenic processes and the contact of water solutions of different mineralization with rocks and oilfields. However, complete exploration of the area in those times was not possible because of lack of modern equipment and devices and new technologies. It should be noted that despite the critical ecological situation prevalent in the Absheron peninsula, no comprehensive studies have been conducted on the radiation level of the area and the diminishing of possible radiation risk among the population living and working in the nearby areas. In this paper, the regularities of distribution of the radiation background in the territory of Absheron peninsula were analyzed and the most dangerous areas in terms of dwelling and operating were identified with proposing necessary measures towards such areas. Moreover, the changing of the radioactive background in relationship with age and types of a soil was determined for the first time based on laboratory analysis of samples taken from the area and the fieldworks conducted. In the presented paper, the radiation background of the Absheron peninsula was studied, thus determining the areas with the average value of the radiation background at 8.5 mcR/h but also the areas where it equaled 400-600 mcR/h, that is, the dangerous levels for living and working.","PeriodicalId":15665,"journal":{"name":"Journal of Environmental Engineering and Science","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139447405","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}

Utilizing biochar prepared from biomass waste is a straightforward and effective method for removing mercury from water. This research centered on producing a thiol-functionalized biochar derived from olive stone waste for the removal of Hg (II) from aqueous solutions. Characterization analyses confirmed the successful functionalization. The biochar, despite having a limited specific surface area (4.14 m2/g) due to raw material nature and pyrolysis conditions, exhibited a notable ability for Hg (II) adsorption, primarily attributed to the thiol-modified surface. Adsorption was assessed using a 2^3 factorial design, with the variables being the adsorption time, biochar dose, and initial Hg (II) concentration in the solution. The biochar dose emerged as the most influential factor, followed by the adsorption time and, lastly the initial Hg (II) concentration. The peak removal efficiency of the model stood at 98.19 %. Kinetics aligned with the pseudo-first-order and intra-particle diffusion models, suggesting a surface adsorption mechanism coupled with pore diffusion. This work accentuates the potential of olive-derived biochar, when thiol-enhanced, in treating aqueous systems contaminated with Hg (II).","PeriodicalId":15665,"journal":{"name":"Journal of Environmental Engineering and Science","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139241855","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}

Analysing drought conditions with various climatic and socio-economic factors is critical for effective drought monitoring. This study investigated the correlation between drought severity and climatic and socio-economic changes in a study area – San Diego County, CA, USA. The drought severity was quantified using three drought indices: standardised precipitation index, standardised precipitation evapotranspiration index and standardised streamflow index. These indices were also used to describe the variation of the drought severity in the study area. The study employed Spearman’s correlation coefficient analysis to evaluate the correlations between the drought indices and climatic and socio-economic factors. The results showed that the drought indices indicated similar variations of the droughts in the study area. However, the severity, duration and frequency of the droughts varied with the timescales in the drought index analysis. Additionally, this study found that the drought conditions based on the three indices had strong negative correlations with precipitation, soil moisture, agricultural area and forest area, which were more pronounced as the timescale increased. The findings will provide insights into effective drought monitoring and management, particularly targeting severe droughts.","PeriodicalId":15665,"journal":{"name":"Journal of Environmental Engineering and Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135666828","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}

Modelling of WWTPs is required for optimising plant performance and choosing the optimum operation strategy. This study simulated the Kabd WWTP in Kuwait using the BioWin software. The plant receives 180 000 m 3 /day of domestic wastewater and comprises primary, secondary (activated sludge) and tertiary treatment stages. Daily data obtained from the WWTP during 2013–2018 were used for modelling plant performance under steady-state operation. The model could describe plant operation and accurately predict the effluent characteristics for the conditions examined. A high correlation (R 2 = 0.95–0.99) was obtained between the predicted and actual values of chemical oxygen demand (COD), biochemical oxygen demand (BOD) and total suspended solids as main parameters characterising wastewater. The tertiary-treated effluent consistently satisfied the water quality criteria for reuse in irrigation. Using the model could aid in securing compliance of effluent quality with the local environmental standards. Factorial analysis revealed that COD and BOD are the most important parameters describing plant performance. Reliability analysis showed that the coefficient of variability was low (0.328) at a level of reliability of 95%, leading to a high coefficient reliability of 0.631, which indicates a highly stable plant performance. It is recommended to include reliability analysis in evaluating plant performance to demonstrate consistency in the ability of the plant to produce effluents satisfying requirements set by environmental authorities.","PeriodicalId":15665,"journal":{"name":"Journal of Environmental Engineering and Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135923733","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}
