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.

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.

Mercury is widespread in our environment. Methylmercury, one organic form of mercury, can accumulate up the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Combustion processes, especially coal-fired power plants, are major sources of mercury contamination in the environment. The U.S. Environmental Protection Agency (EPA) is considering regulating mercury emissions from those plants. Toxicological Effects of Methylmercury reviews the health effects of methylmercury and discusses the estimation of mercury exposure from measured biomarkers, how differences between individuals affect mercury toxicity, and appropriate statistical methods for analysis of the data and thoroughly compares the epidemiological studies available on methylmercury. Included are discussions of current mercury levels on public health and a delineation of the scientific aspects and policy decisions involved in the regulation of mercury. This report is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report also provides an excellent example of the implications of decisions in the risk assessment process for a larger audience.

People are increasingly concerned about potential environmental health hazards and often ask their physicians questions such as: "Is the tap water safe to drink?" "Is it safe to live near power lines?" Unfortunately, physicians often lack the information and training related to environmental health risks needed to answer such questions. This book discusses six competency based learning objectives for all medical school students, discusses the relevance of environmental health to specific courses and clerkships, and demonstrates how to integrate environmental health into the curriculum through published case studies, some of which are included in one of the book's three appendices. Also included is a guide on where to obtain additional information for treatment, referral, and follow-up for diseases with possible environmental and/or occupational origins.

This report details the technical background to the Global Mercury Assessment 2013 - Sources, Emissions, Releases and Environmental Transport (summary for policy-makers) that has been developed in response to Decision 25/5 III, paragraph 36 of the Governing Council of the United Nations Environment Programme (UNEP), that: 'Request the Executive Director, in consultation with Governments, to update the 2008 report entitled Global Atmospheric Mercury Assessment: Sources, Emissions and Transport for consideration by the Governing Council / Global Ministerial Environment Forum at its twenty-seventh session.' This technical background report has been developed in collaboration with the Arctic Monitoring and Assessment Programme (AMAP). As such, this report also constitutes a contribution to the work of AMAP and the Arctic Council

Complex and ever changing in its forms and functions, the element mercury follows a convoluted course through the environment and up the food chain. The process is complicated further by the fact that the difference between tolerable natural background levels and harmful effects in the environment is exceptionally small and still not completely und
