Exposure to arsenic and other potentially toxic elements: health risk assessment and source analysis in the Wuming Basin, Guangxi Province, China

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Feb. 3, 2024

Abstract Guangxi, China, is one of the world's largest karst regions where potential toxic elements tend to accumulate, resulting in high soil background values. This study explores ecological risk, elemental baseline values, and sources regions, expanding research include 21 common elements. The significance this lies its implications for management element pollution, formulation environmental quality standards, remediation areas. In study, 12,547 topsoil samples (0–20 cm) were collected area. Pollution assessment risk evaluation eight (Zn, Ni, Cu, Pb, Cd, Hg, Cr, As) conducted using geo-accumulation index method method. Multivariate statistical analysis was applied analyze total content P, Co, Mn, V, I, S, As, pH, Se, N, CaO, Corg, Mo, F). Additionally, preliminarily quantitatively analyzed principal component analysis-absolute scores-multiple linear regression receptor model. results showed that (1) Zn, As enriched area Ca, Cu might have been influenced by human activities; (2) Zn generally lightly polluted, with Hg having a moderate level; (3) Ni contributions 37.99% 35.07% from geological sources, agricultural fertilization, pesticides. exhibit ranging 39.44 59.22% originating backgrounds activities. P show 45.39% 80.33% surface vegetation. F, Pb 31.63 47.93% acidic rocks parent material, mining activities, transportation. Cd CaO derive 31.67% 40.23%, respectively, material industrial sources. I has 31.94% 31.95% atmospheric 30.56% can serve as scientific basis areas domestically internationally.

Health risk assessment of heavy metal pollution and its sources in agricultural soils near Hongfeng Lake in the mining area of Guizhou Province, China

Frontiers in Public Health, Journal Year: 2023, Volume and Issue: 11

Published: Nov. 10, 2023

Background Accelerated modern industrial processes, extensive use of pesticides and fertilizers remaining issues wastewater irrigation have led to an increasingly severe composite pollution heavy metals in arable land. Soil contamination can cause significant damage ecological environments human health. Mineral resource mining result varying degrees metal surrounding water systems soil. As a plateau lake, Hongfeng Lake has fragile watershed ecosystem. Coupled with the rapid development current socio-economy ongoing activities mining, urbanization agricultural development, soil environment lake land are facing serious pollution. Therefore, situation warrants attention. Methods This study focused on characterizing types conducted sampling laboratory testing farmland Lake. The integrated Nemero comprehensive assessment potential methods were used evaluate status. APCS-MLR model was employed explore sources In addition, health risk analyze association between content cultivated risks. Results single-factor each element ranked descending order: Hg > Pb Cr Cd, being main pollutant factor. entire area subjected mild according index. Pollution source analysis indicated two sources. Hg, As, mainly resulted from Source 1 (industrial natural activities), accounting for 71.99%, 51.57%, 67.39% 68.36%, respectively. Cd attributed 2 (agricultural source), contributing 84.12%. shows that posed acceptable carcinogenic risks humans rather than non-carcinogenic factor, while higher children adults. Conclusion Our identified Lake, evaluated analyzed elements lands greatest impact aim this is provide scientific basis control.
