Soil pollution caused by potentially toxic metal(loid)s (PTMs) near mercury (Hg) mines has attracted extensive attention, yet the status and potential health risks of PTM contamination in soils Hg mining sites have rarely been investigated on a large scale. Global data methylmercury (MeHg), Hg, Cd, Cr, As, Pb, Cu, Zn, Mn, Ni concentrations from areas were obtained published research articles (1999–2023). Based database, levels, spatial distributions, investigated. Results indicated that average percentage MeHg to total agricultural (0.19%) was significantly higher than non-agricultural (0.013%). Indeed, 72.4% these study extremely contaminated with Hg. Approximately 45% examined displayed moderate level As or even more. Meanwhile, Spain Turkey exhibited considerably levels other regions. The mean hazard indices nine PTMs 2.91 0.59 for children adults, 85.6% 13.3% non-carcinogenic adults exceeded safe 1, respectively. In addition, 70.2% 56.7% cancer through exposure five carcinogenic respectively, safety level. showed high exceedance risks, while leading contributors risks. This demonstrates urgent necessity controlling reducing provides an important basis soil remediation.

Heavy metal (HM) pollution nowadays is a hot issue concerning global ecological and food safety. As one of the most important woody bamboos for edible shoots in Southeast Asia southwest China, Dendrocalamus brandisii usually occurs red soil with high HM geological background. However, bioaccumulation process possible risks HMs their cultivation area remain unclear. In this study, comprehensive risk assessment was conducted main D. under two patterns Yunnan, China. The results revealed that moderate to heavy existed study area, while bamboo displayed either no or weak contamination. “large-area intensive afforestation” pattern can better control than “small-scale farmer management” pattern. Strong complex correlations among were unveiled both shoot samples. Cr content 39% samples exceeded China’s national standards. Cu Zn easily accumulated shoots, BCF 0.1235 0.1101, respectively. Bioaccumulations Cd positively correlated concentrations soil. Furthermore, positive matrix factorization model (PMF) identified three sources HMs, i.e., Pb from traffic emissions accounting 30%; Ni, Mn, pedogenic parent material making up 35.4%; mining metallurgical activities 34.6%. Monte Carlo simulations suggested probability total noncarcinogenic children 24.82% primary element health (HQc = 13.94%). These findings emphasize urgent need mitigate may contribute sustainable safety Yunnan similar tropical areas contents.

The Cu-Sb-Hg mineralization of San Giuliano Terme (Monti Pisani, Tuscany, Italy) is characterized by the widespread occurrence deeply altered tetrahedrite-(Hg) hosted within joints and faults in Liassic "Calcari ceroidi" Formation. Through a multi-technique approach (optical scanning electron microscopy, microprobe analysis, single-crystal powder X-ray diffraction, micro-Raman spectroscopy, fluorescence, fluid inclusion analysis), its alteration products have been data about genesis successive supergene weathering collected. Tetrahedrite-(Hg) from has empirical formula Cu9.92Ag0.02(Hg1.64Fe0.30Zn0.04)Σ1.98(Sb3.53As0.56)Σ4.09S12.95, found with scarce gangue minerals represented calcite, baryte, very rare fluorite. formed hydrothermal fluids moderately high salinity (∼ 17.5 wt% NaClequiv.) dominantly metamorphic origin at T ∼ 285 °C. usually fully replaced mixture cinnabar, roméite-group minerals, malachite, rarely azurite.
