Heavy Metal Contamination, Exposure, and Human Health Risk Assessment
This community investigates the environmental distribution of toxic metals, their entry into biological systems, and the resulting health risks to humans and ecosystems.
The work centers on quantifying concentrations of mercury, lead, cadmium, and other trace elements in soil, water, sediments, and food chains. Researchers employ risk assessment models, source apportionment techniques, and spatial distribution mapping to evaluate exposure pathways. Key themes include the bioaccumulation of metals in fish and aquatic organisms, the impact of mining and industrial activities on local environments, and the physiological effects of metal exposure, such as oxidative stress. The literature frequently addresses specific contexts like gold mining, artisanal small-scale operations, and urban pollution, linking environmental contamination directly to human health outcomes and ecological risk.
This research constitutes the largest share of tracked work for mercury, representing 30.7% of all mercury research, and 17.8% of cadmium research. It also accounts for 15.9% of lead research. The community includes 135,271 papers, with the highest publication volumes in Environmental Science and Pollution Research, The Science of The Total Environment, and Environmental Pollution. Recent papers continue to focus on the mechanisms of lead toxicity, the assessment of heavy metals in drinking water and aquatic foods, and the spatial prediction of soil contamination using advanced modeling techniques.
