Abstract Heavy metal pollution in the Nansihu area was evaluated using geo-accumulation index, load and potential ecological risk assessment, with source analysis performed through absolute principal component-multiple linear regression (APCS-MLR) model positive definite matrix factorization (PMF) model. The average concentrations of As, Cd, Cr, Cu, Hg, Ni, Pb, Zn were below standardized background values; however, Hg exhibited significant enrichment, an concentration 1.37 times higher than Jining City soil background, indicating localized point-source driven by anthropogenic activities. Source identified four major contributors: agricultural, natural, transportation, industrial sources. APCS-MLR attributed 34.63%, 29.17%, 25.81%, 10.39% to sources, respectively, while PMF assigned 22.93%, 30.46%, 25.13%, 21.48%. These results highlight distinct roles human activities heavy contamination, particularly demonstrate value integrating models for comprehensive apportionment environmental management strategies.

Microplastic (MP) contamination has become a serious environmental concern that affects terrestrial environments, aquatic ecosystems, and human health. The current study assesses the presence, abundance, morphology of MPs present in surface water Rohtak district, Haryana, India, which is rapidly undergoing industrialization. While morphological studies were conducted through stereo microscopy field emission-scanning electron (FE-SEM), elemental composition polymers was analyzed attenuated total reflectance-Fourier transform infrared (ATR-FTIR). results revealed significantly contaminated by polyethylene, polypropylene, polystyrene. Moreover, abundance found to be 16-28 particles/L with an average value 23 particles/L. Most had fibrous specifics being, fibers (43.9%), fragments (23.7%), films (17%), pellets (15.4%). exhibited size range 0.61-4.87 mm, measured at 2.03 ± 0.04 mm. Also, MP pollution load index values for bodies below 10, indicating low risk category. Though currently designated as "low risk," it important mitigation strategies brought over this juncture further prevent deterioration quality water. Thus, not only intends bring forth impact activities, industrial waste, open waste dumping, inadequate municipal management practices on increasing concentration but also highlights sustainable alternatives address emerging pollutant urban systems. For prevention, implementation stringent regulations on-site plastic segregation critical component preventing disposal bodies. RESEARCH HIGHLIGHTS: particles/L, district fall into hazard categories less than 10. overall water, across all five areas, based color order: white/transparent (39.1%), black (15%), gray (9.1%), green (8.7%), blue (7.8%), red orange (6.3%), yellow (6.1%). dominant polyethylene (PE) (42%) polypropylene (41%) determined FTIR spectroscopy.
