Peculiarities of formation of technogenic mercury pollution in the Amazon as a result of artisanal gold mining

The formation of technogenic mercury contamination in the Amazon basin occurs in a humid tropical climate. Investigations that have been conducted in the river basin. Topazhos showed that when stored outdoors waste dumps the mercury content is reduced by almost to 40 times. As a result mercury, which leached from the minerals transferred to the environment, forming technogenic pollution in the territory, many times greater than the territory of the gold mining plot.
