In which country mercury pollution of body was found
Answers
Explanation:
Natural sources of mercury include volcanic eruptions and emissions from the ocean. Anthropogenic (human-caused) emissions include mercury that is released from fuels or raw materials, or from uses in products or industrial processes.
Some of the mercury circulating through today's environment was released years ago. Land, water, and other surfaces can repeatedly re-emit mercury into the atmosphere after its initial release into the environment. We know that anthropogenic emissions continue to add significantly to the global pool of mercury.
Globally, artisanal and small-scale gold mining (ASGM) is the largest source of anthropogenic mercury emissions (37.7%), followed by stationary combustion of coal (21%). Other large sources of emissions are non-ferrous metals production (15%) and cement production (11%). (United Nations Environment Programme, Global Mercury Assessment, 2018)

Worldwide Emissions
How much mercury is emitted worldwide each year? Estimates of annual global mercury emissions from anthropogenic sources are approximately 2220 metric tons per year. These estimates include mercury that is re-emitted. The world map below provides information about the worldwide distribution of anthropogenic mercury emissions.
