This study investigates Cd and Pb levels in 68 date samples from supermarkets across various regions of Sindh, Pakistan, including 30 samples provided by companies that export date palm fruits globally. Electrothermal atomic absorption spectrometry (ETAAS) with conventional wet acid digestion (CAD) was used for metal determination. Optimization was carried out by Plackett–Burman design (PBD), central composite design (CCD), and response surface methodology (RSM). Results indicated that Cd levels in export samples ranged from 0.012 ± 0.001 to 0.061 ± 0.004, with an average value of 0.031 ± 0.002 mg/kg. Lead levels in these samples varied from 0.028 ± 0.001 to 0.079 ± 0.03, averaging 0.055 ± 0.004 mg/kg. These levels were within the safety limits. However, local market samples exhibited slightly higher Pb levels, ranging from 0.15 ± 0.01 to 0.32 ± 0.03, with an average of 0.26 ± 0.02 mg/kg, exceeding the recommended safety limits. In contrast, the Cd content in local market samples ranged from 0.12 ± 0.01 to 0.16 ± 0.02 mg/kg, remaining below the WHO/FAO.

The 20 samples were collecetd from two districts, water quality and fluoride were estimated using standard protocols. The results showed that in Dharmapur districts, including Dharmapuri and Morappur, the water quality was very poor and the water was in bad condition, and also the water quality and fluoride levels were above the acceptable limits of WHO and TWAD board norms. In Krishnagiri district, such as Hosur, and Larger domestic water samples were highly polluted. The Pochampalli and Hangar, Anjetti, and area ground waters were in poor condition, the rest of the area's water quality and fluoride level are moderate, and may increase in the upcoming years. The quality of water and fluoride levels have crossed the permissible limits of WHO and TWAD board standards in several sites of Krishnagiri and Dharmapuri districts.

Therefore, new alternatives capable of ensuring sustainable industrial growth through cost-effective solutions are being studied. In this context, biosurfactants stand out due to their ability to degrade and remove contaminants from the environment. Therefore, the objective of this study was to evaluate the potential treatment of effluents from the beer industry using biosurfactants produced from wastewater from the beer industry. The biosurfactants were obtained by submerged cultivation at 30°C for 48 h using the bacterium <i>Corynebacterium aquaticum</i> in a mineral medium added of carbon source. The characterization of the biosurfactants was performed in relation to surface tension, emulsifying activity (EA), pH, and ionic character. The analyses were performed at 0, 24, and 48 h. The efficiency of the effluent treatments was evaluated by characterization in duplicate, before, during and after the treatment, regarding the concentrations of biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total solids (TS). The best biosurfactant results were obtained using <i>C. aquaticum</i> in a medium with 10% (v/v) of brewing industry wastewater (BIW) as a carbon source after 48 h of cultivation, reaching a surface tension of 35.1 ± 0.2 mN/m, EA of 40.9 ± 0.5%, and stability under extreme conditions of temperature (−20°C to 121°C), salt (1% to 10%), and pH (4 to 10). Thus, the biosurfactant was applied for 10 days in an aerated biological treatment system. Best results were observed in biosurfactant concentrations of 0.5 CMD (critical micellar dilution), reaching improvement of up to 55.9% for BOD, 23.8% for COD, and 50.6% for TS. Thus, the biosurfactant produced (10% BIW) shows potential as an accelerator in the brewing industry effluent (BIE) treatment process, without purification and sterilization of the biocompound. Therefore, brewery wastewater proved to be a sustainable and nutritional substrate to obtain biosurfactants.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"34 2","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666080","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 global green footprint is continually shrinking owing to overutilization of natural resources. The present research examines the land use pattern that changes from 1990 to 2021 and projected projections for 2041 and 2061 in the Ramgarh District. The study also focuses on how artificial modifications alter the concentration level of pollutants in the atmosphere. The Landsat data utilized for 1990, 2000, 2011, and 2021 were incorporated into the LULC map using supervised classification and for analysis of future predictions for 2041 and 2061 using an ANN-based on MLPNNs (multi-layer perceptron neural networks) for Ramgarh District. It also focuses on the trend and patterns of atmospheric pollutants from data using NASA-GIOVANNI MERRA-2.

The SOC was divided into three fractions (LC—labile carbon, MLC—moderately labile carbon, and LLC—low labile carbon), adopting the chemical method based on oxidation degrees. Reductions in the SOC (28.2%), LC (17.4%), and MLC content (66.7%) were observed at the edge in the small fragment. There was a reduction of SOC (21.3%) and LLC (39.0%) at the edge in the medium fragment, while MLC showed an increase at the edge (70.4%).
