The examined massif is located approximately 60–100 km to the south and southeast of potential industrial contamination sources, including the Upper Silesian Coal Basin (USCB), the Katowice Iron Steelworks, as well as the Bukowno zinc–lead ore mine and smelter. Soil pollution in the study area was assessed utilizing the geoaccumulation index and the potential ecological risk index. At the same time, the Bureau Communitaire de Reference (BCR) sequential extraction technique was employed to assess the mobility of the elements. The results indicate a discernible influence of industrial sources on mountainous environmental contamination, with a robust correlation among lead, zinc, and cadmium concentrations, affirming a common origin. Furthermore, a statistically significant disparity in metal concentrations was observed between the leeward and windward sides of the mountains, notwithstanding the relatively low absolute height. This phenomenon has not been previously documented in low-altitude regions (below 1000 m above sea level). Therefore, despite their modest height, the studied highlands serve as an impediment to the dissemination of airborne pollutants.

Acid rain can be detrimental to soil systems because of their significant ecological functions, such as maintaining microbial activities and retaining nutrients for plants. This study investigated the impact of acid rain on soil physicochemical properties using simulated acid rain in laboratory-scale soil leaching experiments. Multiple sets of simulated acid rain with various pH levels were employed in the leaching processes. The properties of soil, including pH, electrical conductivity (EC), pH buffering capacity, and soil ions, were investigated after leaching with simulated acid rain. Results showed that the pH of simulated acid rain significantly influenced soil pH and the pH of soil leachate. There was a positive correlation between the pH levels of simulated acid rain and those of the soil. The surface soil (0–10 cm in depth) maintained a higher pH buffering capacity than the slightly deeper soil (10–40 cm in depth). Fourier transform infrared (FTIR) spectroscopic analysis indicated the consumption of inorganic carbonate functional groups, which could explain the loss of soil base cations.\u0000 </div>","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"53 7","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

P. aeruginosa JU_CHE_01 shown the ability to break down 600 mg/L concentration of RR120 dye along with many harmful textile azo dyes. The strain also showed resistance to ampicillin and cefradine but remained susceptible to other tested antibiotics. Five process factors were evaluated for optimal condition using the Taguchi approach. Three physicochemical parameters (pH, temperature, and inoculum dose) and two media components (glucose and yeast extract) were optimized because of their significant impact on RR120 biodegradation. The L-18 orthogonal arrays (OAs) architecture was utilized in the design of multiple experimental studies. Analysis of the experimental data was done using the signal-to-noise (S/N) ratio with the “larger is better” features to determine the key variables and ideal circumstances for optimizing RR120 dye biodegradation. When the predicted data was validated using the confirmatory experiments, it was found that under the ideal conditions of glucose and yeast extract of concentration 1 g/L each, pH 8, temperature 37°C, and inoculum dose 10% (v/v) in 48 h, 97.63% of the RR120 dye degradation could be achieved, leading to a 66.75% enhancement in the RR120 degradation.

The saffron stamen was utilized to obtain sporopollenin, which was then magnetized employing Fe3O4 followed by GO to produce a sorbent of the Fe3O4-SSSP/GO type. The result indicates that the Fe3O4-SSSP/GO is a suitable sorbent for solid-phase extraction of four PAHs: benzo[a]anthracene (BaA), chrysene (Chr), benzo[b]fluoranthene (BbF), and benzo[a]pyrene (BaP), found in tea and saffron samples. Scanning electron microscopy and Fourier-transform infrared spectroscopy were used to characterize the sorbent. Taguchi analysis was employed to optimize the main parameters for extraction, such as sample volume, sorbent amount, desorption volume, and pH of the investigated PAHs. The calibration curve for determining BaA, Chr, BbF, and BaP was investigated in the 0.5 to 500 ng mL−1 range.

Through biochemical and molecular tests, these bacteria were identified as Pseudomonas oryzihabitans, Enterobacter kobei, and Serratia species. The bacteria were cultured for 10 days in broth and soil media with DZ concentrations of 10 and 20 ppm. The degradation and utilization of the toxin by the bacteria were measured using gas chromatography. The results indicated that P. oryzihabitans degraded the toxin at concentrations of 10 and 20 ppm in liquid medium by 47.1% and 27.45%, respectively. In soil medium, the bacteria degraded 96.5% and 97.1% of the toxin at the same concentrations. Serratia sp. degraded DZ in broth medium with initial concentrations of 10 and 20 ppm by 64.3% and 78.4%, respectively. Additionally, these bacteria were able to degrade DZ by 90.2% and 98.25% in soil. E. kobei consumed DZ in the broth and soil media at rates of 23.1% and 17.95% and 31.19% and 88.05%, respectively.
