Priority should focus on strengthening habitat protection in the southeastern Qinghai-Xizang Plateau, where some stable habitats remain outside protected areas.

This study analysed NO<sub>2</sub> concentrations in Gazipur from 2019 to 2022 using Sentinel-5P TROPOMI data on the Google Earth Engine (GEE) platform. Correlations and regression analysis were done between NO<sub>2</sub> levels and various environmental factors, including land surface temperature (LST), normalized difference vegetation index (NDVI), land use and land cover (LULC), population density, road density, settlement density, and industry density. The results reveal significant seasonal variations. The highest annual mean NO<sub>2</sub> concentration (3.1 × 10<sup>–</sup><sup>4</sup> mol/ m<sup>2</sup>)was recorded for winter 2021, and the lowest (1.1 × 10<sup>–4</sup> mol/m<sup>2</sup>) was for monsoon 2022. The study demonstrates a significant positive correlation between NO<sub>2</sub> concentrations and LST (0.47), road density (0.55), settlement density (0.44), and industrial density (0.35) and a negative correlation with NDVI (− 0.4).

Most past studies highlighted the significance of LULC changes and their driving forces in various locations. However, comprehensive analyses that combine the impact of land management technologies (LMTs) on LULC changes using GIS and remote sensing tools have not been widely addressed. Thus, the study analyzes the effects of LMT adoptions on LULC dynamics and the Normalized Difference Vegetation Index (NDVI) in the Goyrie watershed from 1993 to 2022. It also examines household perceptions of the cause of LULC changes. Methodologically, Landsat 5 TM (1993), Landsat 5 ETM + (2008), and Landsat 8 OLI/TIRS (2022) images were employed to analyze LULC changes and NDVI. Binary logistic regression models were used to identify households’ perceptions of the causes of LULC changes. The findings revealed that the Goyrie watershed has experienced significant LULC changes since 1993. During the entire study period, the shares of grassland, shrub land, cultivated land, and settlement areas increased by 89.4%, 8.5%, 53.6%, and 1613.4% from their original sizes, respectively. Conversely, the coverage of bare land and forest land declined by 99.5% and 99.7%, with annual rates of decline of 3.29% and 3.3%, respectively. Throughout the study period, the increasing trends in grassland and shrub land, along with the decline in bare land, were attributed to LMT practices. The NDVI values of moderate and dense vegetation density decreased by 81.8% and 92.2%, respectively, from 1993 to 2022 due to the expansion of settlement areas and cultivated lands. Population pressure, expansion of settlements and agriculture, fuel extraction, LMTs, and policy issues significantly influenced the LULC changes.

However, the success of deep learning is contingent upon the quality of the training data.

The accuracy of pixel-based and object-based classification was 83.1% and 83.5%, respectively, with corresponding kappa values of 0.786 and 0.791. These accuracies highlighted the efficient performance of the object-based method when integrated with a deep learning classifier. These results can serve as a valuable reference for future studies, aiding in the improvement of accuracy while potentially saving time and effort.

Active moss biomonitoring was applied to assess the impact of potentially toxic elements on air pollution in five urban areas of the region. In each of the chosen urban regions, the moss bags were exposed in November and December of 2022 at locations with varying degrees of anthropogenic pressure. Using a direct mercury analyzer in conjunction with coupled plasma-optical emission spectrometry, the content of sixteen major and trace elements (Al, Ba, Co, Cd, Cr, Cu, Fe, Mn, Ni, P, Pb, Sr, S, V, Zn, and Hg) was ascertained. Compared to unexposed the exposed moss bags showed a higher content of potentially toxic elements. To draw attention to the relationships between the elements and connect them to potential emission sources, correlation, and principal component analyses were used. A strong positive correlation was obtained for elements emitted by coal mining and burning, the metallurgical industry, and vehicles. To evaluate the degree of environmental pollution and the element enrichment in the moss, the relative accumulation factor and contamination factor were computed. The mean values of the contamination factor ranged from 0.83 to 4.8, indicating the exposure sites show no contamination to moderate contamination status.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 2","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142941198","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}
