Due to its inherent characteristics, mercury contamination from gold
mining is a major environmental problem compared to past mercury
contamination from industrial point sources. The worsening of
social-economical conditions and increasing gold prices in the late
1970s resulted in a new rush for gold by individual entrepreneurs for
whom Hg amalgamation is a cheap and easily carried out operation. Even
after the present-day mining areas are exhausted, the mercury left
behind will remain part of the biochemical cycle of the tropical forest.
This book reviews the current information on mercury from gold mining,
its cycling in the environment and its long-term ecotoxicological
impact. The book is illustrated with numerous diagrams and photographs.
