In this study, 385 topsoil samples (0–20 cm) and 118 deep soil samples (150–200 cm) were collected from Nanyang City to investigate the spatial distribution, contamination, and source allocation of TMs. Geographic information system analysis, contamination factor (CF), geo-accumulation index (Igeo), and positive matrix factorization (PMF) model were utilized. The results showed that the mean contents of Cu, Hg, Pb, and Zn in the study area's topsoil (25.50, 0.035, 28.51, and 79.46 mg kg−1) exceeded background values. CF and Igeo results indicated that over 60% of soil samples were contaminated by Hg, the main contaminant in soil. By combining correlation and PMF analysis, three sources of TMs were identified for (a) Pb (75.4%), Hg (63.7%), and Zn (55.6%), primarily associated with industrial emissions and atmospheric deposition; (b) Co (57.5%), Cr (50.8%), Cu (59.2%), and Ni (46.4%) mainly originated from natural sources; and (c) As (72.8%) primarily from agricultural activities. The proportions of the three sources were 36.27%, 39.76%, and 23.97%, respectively. Anthropogenic sources contributed the most to soil TMs (60.24%), higher than natural sources, indicating substantial accumulation of TMs in topsoil due to significant anthropogenic activities.

We collected samples from a garden in Iran where DZ has been used for a long time. This allowed us to extract three types of bacteria capable of degrading DZ. 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. According to the results, P. oryzihabitans exhibited the highest degradation capacity compared to the other bacteria. Collectively, these three bacteria demonstrate a significant ability to biologically remediate environments contaminated with DZ.\u0000 </div>","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"53 4","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857105","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}

However, the prior research on the nexus between TUN and the environmental quality (ENQ) records contradictory results, which may be inconvenient when recommending environmental protection policies. The goal of this research was to look into the asymmetric link between TUN and ENQ in the selected newly industrialized economies. Previous studies utilized panel data methods, yielding similar conclusions about the linkage between TUN and ENQ, regardless of the truth that many economies did not develop such interconnectednhess individually. On the other hand, the current work employs a distinctive methodology, “quantile-on-quantile,” that allows researchers to analyze time-series dependency in every nation by providing universal yet economy-specific details on the association between the variables. As per estimates, TUN boosts ENQ in majority of our selected nations. Moreover, the results reveal that the degree of asymmetries amidst the variables differs by nation, highlighting the requirement for policymakers to pay particular attention while implementing trade and environment sustainability policies.\u0000 </div>","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"53 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689920","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}

This study delves into the sustainable trajectory for urban agglomerations, focusing on the Beijing–Tianjin–Hebei (BTH) urban agglomeration in China. Employing the STIRPAT model and Conley–Ligon model, it assesses the impact of socioeconomic factors on environmental pollution and their spillover effects. The study incorporates three distinct developmental scenarios designed to simulate regional economic growth and environmental protection. Our findings reveal a substantial influence of local socioeconomic development and spatial spillover effects from neighboring counties within the BTH region on local PM2.5 concentration. Economic development level and environmental governance expenditure emerge as pivotal factors affecting the increase and decrease of PM2.5 concentration, with spillover effects observed in neighboring counties. The effectiveness of balancing air pollution and the economy is better under the Zoning Cooperated scenario than under the local Government Planning scenario and trend extrapolation scenario. This means that more than 96% of the 100 million people in the counties will live in areas with clean air. In light of these findings, the research proposes pertinent policy recommendations, offering a novel and efficacious solution for urban agglomerations in rapidly developing countries or regions worldwide grappling with the intricate trade-off between air pollution and economic development.\u0000 </div>","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"53 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638658","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}

This type of weir consists of rack bars to control the deposition of sediments and floating debris. This article presents the investigations of the effects of different parameters, particularly the spacing of rack bars, specific energy of flow in the approach channel, velocity head, and porosity of rack bars on the discharging ability of trench weirs. Due to their greater flexural rigidity, flat bars are chosen in the current investigation from a structural perspective. The experiment was carried out in an open channel taking different combinations of bed slope, rack slope, and spacing of flat rack bars while testing under free flow conditions and having a pre-defined discharge in the approach channel. In addition, the discharge characteristics and coefficient of discharge (Cd) of the trench weir have been examined with varying clear spacing of rack bars, specific energy of approach flow, velocity head, and porosity of rack bars. The findings indicate that, in free flow conditions, Cd decreased as the porosity, clear spacing of rack bars, and specific energy of the approach flow increased. Further, during the analysis of experimental data, it was observed that Cd does not show any systematic pattern with velocity head. Thus, this study provides valuable insights on trench weir performance and the variables affecting discharge characteristics of trench weirs.\u0000 </div>","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"53 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554518","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}
