Heavy metals pollution from smelting activities: A threat to soil and groundwater

Ecotoxicology and Environmental Safety, Год журнала: 2024, Номер 274, С. 116189 - 116189

Throughout the literature, word "heavy metal" (HM) has been utilized to describe soil contamination; in this context, we characterize it as those elements with a density greater than 5 g per cubic centimeter. Contamination is one of major global health concerns, especially China. China's rapid urbanization over past decades caused widespread urban water, air, and degradation. This study provides complete assessment contamination by heavy metals mining smelting regions. The (HMs) includes an examination their potential adverse impacts, origins, strategies for remediation contaminated metals. presence can be linked both natural anthropogenic processes. Studies have demonstrated that soils present risks individuals. Children are more vulnerable effects metal pollution adults. results highlight significance operations Soil poses significant carcinogenic non-carcinogenic, particularly children individuals living heavily polluted areas. Implementing physical, chemical, biological techniques most productive approach addressing metal-contaminated soil. Among these methods, phytoremediation emerged advantageous option due its cost-effectiveness environmentally favorable characteristics. Monitoring utmost importance facilitate implementation improved management soils.

Introduction The primary source of anthropogenic atmospheric mercury (Hg) emissions globally is artisanal and small-scale gold mining (ASGM). Estimates Hg from ASGM are poorly constrained due to a lack monitoring data the informal, generally unregulated nature this industry. Trees accumulate gaseous elemental (GEM) in bolewood following stomatal uptake thus have potential be used as biomonitors quantify spatial temporal footprint ASGM. Methods We collected tree cores Ficus insipida at three mining-impacted two remote, unimpacted sites Peruvian Amazon (n = 4 trees per site). Results show that ring concentrations were higher near activity located towns (6.0 ng g −1 ) compared remote (0.9 recent rings strongly linearly correlated with GEM across all (p < 0.0001, r 2 0.64), especially dry season when there enhanced 0.76), highlighting for GEM. At most impacted sites, tree-ring increased over time response intensification Discussion Thus far, applications dendrochemistry pollution been largely restricted coniferous species temperate regions, but study shows tropical also pollution. conclude suitable biomonitor powerful tool characterizing spatial, potentially neotropics.
