Soil Heavy Metal Pollution and Health Risk Assessment Based on Monte Carlo Simulation: Case Study of Xicheng Lead-Zinc Mining Area

Sustainability
To investigate the status of heavy metal pollution and the associated ecological and health risks in farmland surrounding the Xicheng lead and zinc mining area, we collected soil samples (0–20 cm) and measured the level of As, Ni, Cu, Zn, Cd, Pb, Hg, and

An overview of potentially toxic element pollution in soil around lead-zinc mining areas

Environmental Reviews
Metal mining activities have been major contributors of potentially toxic elements (PTEs) in the environment, leading to substantial soil pollution. One such example is lead-zinc mining around the world.

Bioavailability of Copper and Zinc in Mining Soils

Archives of Environmental Contamination and Toxicology, 2011
The soil-contact exposure pathway can be the main driver of ecological risk assessments. There is currently no standard method to measure bioavailability of metals in soil to ecological receptors, yet the influence of metal bioavailability on toxicity has been known for decades and is a major factor influencing risk to ecological receptors ...

Invasive Amaranthus spp. for heavy metal phytoremediation: Investigations of cadmium and lead accumulation and soil microbial community in three zinc mining areas.

Ecotoxicology and Environmental Safety
Amaranthus spp. are a group of strongly invasive and vigorous plants, and heavy metal phytoremediation using alien invasive Amaranthus spp. has been a popular research topic.

Lead and zinc mining in the Driftless Area

The Physical Geography and Geology of the Driftless Area: The Career and Contributions of James C. Knox, 2019
ABSTRACT Lead and zinc ore minerals occur in the middle Ordovician Sinnipee Group dolomites in southwest Wisconsin and adjacent areas of northwest Illinois and northeast Iowa. Europeans began mining lead deposits as early as the mid-1600s; production of lead ore and smelting of lead reached a peak ca. 1850. Mining and production from the

Preparation of phosphorus-modified biochar for the immobilization of heavy metals in typical lead-zinc contaminated mining soil: Performance, mechanism and microbial community.

Environmental Research, 2022
The use of modified biochar for the remediation of heavy metal (HM) has received much attention. However, the immobilization mechanism of biochar to multiple HMs and the interaction of different forms of HMs with microorganisms are still unclear.

Vegetation establishment on a deposit of zinc mine wastes

Environmental Pollution, 1989
Field trials concerning the establishment of plant cover on a deposit of wastes from the Ammeberg zinc mine in central Sweden were carried out during 1976-1985. Different soil conditioners and manures were applied and plant species cultivars were evaluated with regard to plant biomass, vigour, durability and content of zinc, lead and cadmium.

Ancient lead and zinc mining in Rajasthan, India

World Archaeology, 1984
Abstract Lead and zinc mines in Rajasthan, India, were examined, in relation to, especially, the early use of zinc as a metal. Carbon dates of circa 2000 years before present established Zawar as the world's oldest zinc mines. Large‐scale mining for lead at Rajpura‐Dariba goes back to circa 3000 years before present. Major features found are described,
