“…Almost all of the pollution originates from agricultural NPSP and domestic sewage. At present, the research on NPSP in this area is mainly focused on NPSP output characteristics, pollution load estimation, pollution prevention and control technologies and management Kim et al, 2021). However, the study of the effect of NPSP on microbial ecological processes in river sediments has not been reported in detail, especially the mechanism underlying the effect of NPSP on fungal community construction in sediments, which is still unclear .…”

Nonpoint source pollution (NPSP) from human production and life activities causes severe destruction in river basin environments. In this study, three types of sediment samples (A, NPSP tributary samples; B, non-NPSP mainstream samples; C, NPSP mainstream samples) were collected at the estuary of the NPSP tributary of the Jialing River. High-throughput sequencing of the fungal-speci c internal transcribed spacer (ITS) gene region was used to identify fungal taxa. The impact of NPSP on the aquatic environment of the Jialing River was revealed by analysing the community structure, community diversity and functions of sediment fungi. The results showed that the dominant phylum of sediment fungi was Rozellomycota, followed by Ascomycota, Chytridiomycota, Basidiomycota, Mortierellomycota and Zoopagomycota (relative abundance>1%). NPSP caused a signi cant increase in the relative abundances of Rozellomycota, Saccharomycetes, Microascales, Saccharomycetales, Branch02 and Branch03. In addition, it caused a signi cant decrease in the relative abundances of Chytridiomycota, Dothideomycetes, Capnodiales, Glomerellales, Xylariales and Chaetothyriales.Moreover, NPSP caused signi cant changes in the physicochemical properties of Jialing River sediments, such as pH and available nitrogen (AN), which signi cantly increased the species richness of fungi and caused signi cant changes in the fungal community β-diversity (P<0.05). pH, total phosphorus (TP) and AN were the main environmental factors affecting fungal communities in Jialing River sediments. The functions of sediment fungi mainly involved three types of nutrient metabolism (symbiotrophic, pathotrophic and saprotrophic) and 75 metabolic circulation pathways. NPSP signi cantly improved the NONOXIPENT-PWY, PENTOSE-P-PWY, and PWY-6837 metabolic circulation pathway functions (P<0.05) and inhibited the PWY-7118, PWY-5920, and PWY-6609 metabolic circulation pathway functions (P<0.05). Hence, NPSP causes changes in the community structure and functions of sediment fungi in Jialing River and destroys the stability of the Jialing River Basin ecosystem.

“…According to data, NPS contamination has harmed 30-50% of surface water sources, making it an increasingly serious threat to water quality and aquatic ecosystem restoration [3]. Every year, approximately 0.3-0.8% of cropland worldwide is impacted by severe deterioration, rendering the soil unsuitable for agricultural production [4,5]. Concerning this, NPS pollution has emerged as the primary contributor to water pollution in many Korean rivers and lakes, leading to the degradation of water quality [6].…”

This study investigated the effects of nonpoint source (NPS) pollution reduction and pollutant dynamics in a highland agricultural watershed in Korea. We employed the SWAT model to simulate hydrological processes and pollution transport within the watershed. The model incorporates future climatic scenarios derived from downscaled climate projections to assess their impacts on NPS pollution and pollutant reduction methods. These changes lead to heightened surface runoff and erosion rates, resulting in elevated sediment and nutrient concentrations. The projection indicates an anticipated increase in the annual average temperature by 1.3 to 2.1 °C by the mid-century, under scenarios SSP126 and SSP585. Additionally, precipitation levels are projected to increase by 31 to 61 mm from the baseline to the end of the century. Variations in hydrological components such as evapotranspiration, streamflow, and soil moisture are expected to range from +3.2 to +17.2%, −9.1 to +8.1%, and 0.1 to 0.7%, respectively, during the years 2040 and 2080. Fluctuations in TN, SS, and TP loading are estimated to range from −4.5 to +2.3%, −5.8 to +29.0%, and +3.7 to +17.4%, respectively. This study emphasizes the importance of adaptive management options for stakeholders and the need for adaptive management options to reduce nonpoint source pollution and protect water quality to maintain sustainable water supplies and conserve the environment in this watershed.

“…Kabir et al (2021) indicated that tire wear from vehicles on roads might release synthetic rubber particles into rivers. Thus, rubber from tires, etc., circulates in the ecosystem as a non-point pollution source (NPS) due to various causes, such as rainfall (Kim et al, 2021). MPs in NPS can ow into various water sources and increase the concentrations of MPs, and many studies have reported that MPs are ingested throughout the food-chain (Cole et al, 2011).…”

Detection of micro-plastics (MPs) was performed for various water sources, sediments, and shes using FTIR, microscopic analysis, and image mapping. To derive correlations between MPs in carp and river crabs in Ansan River (AR), the Pearson correlation coe cients were determined. Carp and river crabs had coe cients of 0.888 and 0.724 AR, respectively. Therefore, AR, carp, and river crabs had a high positive correlation. The MPs detected in sediments were higher than those in main-waterway (MW) and rivers, which was the opposite the MPs in water sources. It is believed that MPs are carried toward shore by ocean tide. The size of most of the sediment MPs was 20-49 µm, representing 64.1% of the entire population. MP pollution by non-point pollution sources (NPS) was investigated, with abundances of MPs between the dry season and rainy season with differences of 2 to 3 times in AR and Ansan River sediment (ARS), respectively. The plastics detected in this study were PET, PP, and PE, which originate from synthetic bers, scrubs, and packing material. The MPs of various water sources, sediments, shes, and NPS were detected in this study. It was determined that the in ow of MPs into rivers could have been due to non-point source pollutants from household items, roads, plants, and soil around the water sources.
