The gold rush in the Amazon region is creating serious environmental problems that imperil future generations. Mercury pollution is a particularly serious problem that should be addressed through an education campaign, through the use of more appropriate (and inexpensive) extraction technologies, and through an effective combination of command and control measures and market- based incentives.

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.

The purpose of this book is to examine both the positive and negative socioeconomic impacts of artisanal and small-scale mining in developing countries. In recent years, a number of governments have attempted to formalize this rudimentary sector of industry, recognizing its socioeconomic importance. However, the industry continues to be plagued by

Mercury pollution and contamination are widespread, well documented, and continue to pose a public health concern in both developed and developing countries. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly to include the fields of biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists begun to establish a holistic approach to studying mercury pollution that integrates chemistry, biology, and human health sciences. Mercury in the Environment follows the process of mercury cycling through the atmosphere, through terrestrial and aquatic food webs, and through human populations to develop a comprehensive perspective on this important environmental problem. This timely reference also provides recommendations on mercury remediation, risk communication, education, and monitoring.

This 108-page report reveals that children as young as six dig mining shafts, work underground, pull up heavy weights of ore, and carry, crush, and pan ore. Many children also work with mercury, a toxic substance, to separate the gold from the ore. Mercury attacks the central nervous system and is particularly harmful to children.
