India is a major emitter of mercury to the environment. This mini-review condenses the information available since 2008 on mercury in air, soil, sediment, biota and human biomarkers near industrial locations. Information from eight regions was analyzed. More than 40% of studies did not report sufficient QA/QC information on analysis methods. Highest quality was observed for studies on human biomarkers, biota, and sediments, and the lowest on water quality. Concentrations of mercury in sediments (up to 3650 µg/kg), human biomarkers (up to 31 µg/g) and fish (up to 3 µg/g) in the vicinity of coal-fired power plants and iron and steel were high in general, and sometimes comparable to or higher than the global guideline, screening or reference values. Overall, impacts of industrial activities on mercury pollution of surrounding environment were evident, and warrant a speedy assessment of other industrial areas and implementation of mitigation measures. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
