The geological background level of metals plays a major role in mineral distribution and watershed diffuse heavy metal (HM) pollution. In this study, field research distributed hydrological model were used to analyze the distribution, sources, pollution risk HMs sediments with high HM backgrounds. Study showed that landcover promoted transport differences from upstream estuary. And main sources Co, Ni, V estuarine natural sources. Sources Pb Zn dominated by anthropogenic accounting for 76% 64% their respective totals. overall ecological anthropogenically sourced was (46.6%), while contributions Co Ni also relatively high, 35.70% 33.40%. Moreover, redundancy analysis variations most sensitive soil erosion mineralizing rock distribution. spatial patterns significantly influenced P loading, precipitation, forest This combination experiments improves understanding variation provides new perspective formulating effective management strategies.

This article delves into the utilization of biochar derived from diverse waste sources as an effective adsorbent for removing heavy metals wastewater. A comprehensive quantitative analysis was conducted, scrutinizing key characteristics sourced various materials its metal adsorption potential in wastewater treatment. is based on extensive dataset spanning 2013 to 2023, comprising a total 608 articles retrieved Scopus database. Advanced bibliometric and scientific mapping techniques were employed facilitated by tools like VOSviewer Tableau gain insights visualize trends this field. The findings indicate consistent upward trajectory publication research documents over recent years. Several countries have emerged productive hubs, demonstrating substantial influence within their respective regions through wide-ranging collaborations. Notably, China, India, United States, South Korea, Australia, Malaysia stand out most influential contributors. Furthermore, study explores efficacy adsorbing ions, shedding light relationships between these variables. Keyword conducted identify current hotspots domain. In sum, paper offers perspective evolution formidable It serves catalyst further endeavors, encouraging scholars explore novel or modifications that can enhance performance while ensuring stability efficiency.

Systematic and scientific assessments on heavy metal pollution are greatly important to protecting the coastal eco-environment. In this paper, spatial distribution, degree, ecological toxicity possible sources of eight elements collected from 126 marine 715 terrestrial surface sediments surrounding Dingzi Bay were analyzed by obtaining concentration measurements. The results revealed that concentrations metals followed a pattern: inner bay > areas outer bay. Cr, Ni, Cu, Zn, Cd, Pb, Hg found accumulate in fine particles (<0.063 mm), while As showed an association with specific (>0.25 mm <0.016 mm). Spatial patterns varied non-polluted low levels overall, localized contamination individual elements. addition natural sources, four types anthropogenic identified settings. Agricultural pollution, characterized predominance, exerted profound effects both environments. Industrial featuring dominance, was widespread land environment predominantly linked atmospheric deposition. Traffic marked elevated Pb concentrated around factories densely populated areas. Maritime comprising Hg, primarily occurred nearshore outside findings study provide data authorities charge sustainable zone management South Yellow Sea.
