Ending the toxic trail of small-scale gold mining
The chemical, which has been used in mining for over 3,000 years, does not degrade in the environment. Research shows that forest canopies near small-scale gold mining sites can intercept and accumulate large volumes of atmospheric mercury pollution. This means mercury can build up and be passed along the food chain.
