This indicates that anthropogenic sources of Pb could be identified more sensitively in acid extracts than in total digests. The Pb isotope ratios showed that burning coal and smelting ore are the predominant anthropogenic sources of Pb in the study area, i.e., a lead–zinc smelter and a coking plant are major sources of Pb in the study area.

Zinc ores in India are concentrated in Rajasthan, and the biggest smelting plants are situated in the state. The smelting of zinc is a capital-intensive business and involves many stages between mining and the final product. As zinc and lead ores are often mixed, the mining and smelting of both metals are done at a zinc smelter plant.
