Therefore, the prediction of PM concentration has become a topic of great significance to reduce air pollution and assess the effects on public health. In this study, the grey prediction model (GM (1,1)), the discrete grey model (DGM (1,1)), and the grey Verhulst model (GVM (1,1)) were used to estimate the PM10 concentration of the cities Amasya, Çorum, Ordu, and Samsun in the Middle Black Sea region, for the period from 2022 to 2026. The accuracy of the GM (1,1), DGM (1,1), and GVM (1,1) models in fitting data was calculated using the mean absolute percentage error (MAPE) value. Since three types of prediction models of MAPEs were less than 20%, they were considered a good value for prediction performance. Furthermore, the results showed that the PM10 concentrations of Amasya, Çorum, and Ordu showed a downward trend over the next 5 years. However, the GVM (1,1) model showed an upward trend in the yearly average PM10 concentration in Samsun. In conclusion, these models could be considered a reliable approach in early warning systems for emissions reduction and as a long-term policy for managing air quality in the Middle Black Sea region.","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"51 10","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50132240","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}

The effect of landuse on SOC was studied in the Shaheed Bhagat Singh Nagar district of Punjab (India). Surface (0–15 cm) and subsurface (15–30 cm) soil samples were collected under different land uses (cropland, forest, scrubland, and plantation) using stratified random sampling. Soil samples were analyzed for soil texture, bulk density, pH, electrical conductivity, organic carbon, Olsen P (available P), NH4OAc–extractable K (available K), and CaCl2 extractable S (available S) using standard methods. Ordinary kriging was used to study the distribution of soil properties in different land uses. Soil organic carbon under future climate was simulated using Rothamsted carbon (RothC) model with current landuse and management practices. Organic carbon in surface and subsurface soils was in the order: Forest > scrubland > plantation > cropland. The content of organic carbon, available P, K, and S decreased with increasing soil depth. The simulated SOC content in cropland soils under future climate may reduce, and in soils under forest, plantation and scrubland may increase by the year 2100. These results suggest that the landuse system is one of the major factors affecting SOC stocks. The study of organic carbon in different landuses could help the famers and policy makers to take measures for increasing SOC stocks to mitigate the climate change and also for sustainable agriculture.","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"51 12","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135645743","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}

Its excessive discharge into wastewater is constant and in high concentrations, likely affecting the physiology of microbial communities. We compared the physiological community profile of activated sludge (AS) bacteria with and without prior in vitro exposure to a high concentration of BAC (10 mg L−1). We measured the community functional diversity, carbon substrate multifunctionality, and the median effective concentration that inhibits carbon respiration (EC50) using Biolog EcoPlates supplemented with a gradient of 0–50 mg L−1 of BAC. Surprisingly, we did not find significant differences in the physiological parameters among treatments. Certain abundant bacteria, including Pseudomonas, could explain the community's tolerance to high concentrations of BAC. We suggest that bacterial communities in wastewater treatment plants’ AS are “naturally” adapted to BAC due to frequent and high-dose exposure. We highlight the need to understand better the effects of QACs in wastewater, their impact on the selection of tolerant groups, and the alteration in community metabolic profiles.","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"51 11","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109161813","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}

In order to carry out metal contamination assessment and human health risk assessment of agricultural soils, a total of 662 cultivated soil samples were collected from two industrially oriented towns and three agriculturally oriented towns of Shifang City, Southwest China. Various indices were applied to analyze the pollution levels of soils caused by metals (Cr, Fe, Pb, Sr, Ti, V, Zn, and Zr). The relatively high values of the geo-accumulation index (Igeo) and the enrichment factor (EF) suggested that Sr, V, and Zn had cumulative trends in the soils. The average pollution load index (PLI) values of the industrial towns (1.19 and 0.99) were higher than those of the agricultural towns (0.92, 0.53, and 0.43), demonstrating the contribution of industrial activities to soil metal enrichment. The health risk assessment from the five towns indicated that Cr and V were the dominant contaminants in soils with high potential health risks. Dermal contact was the major pathway of the exposure of children and adults to Cr and V. This study improved the understanding of the pollution levels of metals in Shifang agricultural soils and put forward the necessity of minimizing the health risk of Cr and V in agricultural soil.","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"51 11","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109175548","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}

As an important biological constituent of urban landscape, herbaceous plants can provide ecosystem service such as particulate matter (PM) retention. However, the evaluation of this ecosystem service for herbaceous plants has been seldom made. The present study compared the PM retention capacity of four herbaceous plants commonly used for urban greening in North China—Liriope spicata (Thunb.) Lour., Lolium perenne L., Festuca elata Keng ex E.B.Alexeev, and Poa pratensis L. and explored the correlation between leaf micromorphological traits and PM retention using an in situ experiment. PM with different particle sizes, including PM>10 (10–100 µm), PM10 (2.5–10 µm), and PM2.5 (<2.5 µm), were separately evaluated. We found that L. spicata had the greatest PM retention capacity for all particle sizes among the four species. Electron microscopy revealed that leaves with higher groove proportion, larger stomatal size and greater densities of stomata and trichome generally had higher PM retention capacity. The study showed the correlation between leaf micromorphology and PM absorption, providing a scientific basis for further quantitative studies on the ecosystem service of PM absorption provided by herbaceous plants.","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"51 10","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50149775","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}
