Download or read book Mercury from Gold and Silver Mining written by Luiz D.de Lacerda and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Artisanal Small Scale Gold Mining written by Katherine von Stackelberg and published by World Bank Publications. This book was released on 2022-06-13 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: This framework document provides a pragmatic approach for designing representative studies and developing uniform sampling guidelines to support estimates of morbidity that are explicitly linked to exposure to land-based contaminants from small-scale artisanal gold mining activities. A primary goal is to support environmental burden of disease evaluations, which attempt to attribute health outcomes to specific sources of pollution. The guidelines provide recommendations on the most appropriate and cost-effective sampling and analysis methods to ensure the collection of representative population-level data, sample size recommendations for each contaminant and environmental media, biological sampling data, household survey data, and health outcome data. This framework focuses on small-scale artisanal gold mining (ASGM) activities that are known to use and generate mercury (Hg) as well as other metals, such as arsenic (As) and lead (Pb), depending on the specific ores being mined. A particular concern with Hg is the conversion to methylmercury (MeHg) in aquatic environments, leading to bioaccumulation and biomagnification in fish that may be locally consumed. Exposure to Hg, MeHg, and Pb are strongly associated with neurodevelopmental health outcomes in children. Exposure to Hg and MeHg are also associated with neurological illnesses in adults. Exposures to Pb are associated with renal outcomes in children and adults, and cardiovascular outcomes in adults. Exposure to As are associated with neurodevelopmental health outcomes in children, arsenicosis and skin disorders in children and adults, and potential cancers in adults, including skin, bladder, and lung. The primary objective of this framework is to guide research to assess the relationship between environmental contamination, exposures, and health outcomes related to a subset of contaminants originating from ASGM activities for particularly vulnerable populations (such as children) and the general population within a single household in the vicinity of ASGM sites in low- and medium-income countries. To achieve this objective, biomonitoring and health outcome data are linked to household survey and environmental data (for example, soil, dust, water, agricultural products, fish) at the individual level from an exposed population compared to individuals from an unexposed (reference) population. Data on exposures and health outcomes in the same individual across a representative set of individuals is required to support an understanding of the potential impact of ASGM activities on local populations. These guidelines can also assist in building local capacity to conduct environmental assessments following a consistent methodology to facilitate comparability across ASGM sites in different geographic areas. Sampling strategies and methods are prioritized given information needs, resource availability, and other constraints or considerations. The framework includes a number of supporting appendixes that provide additional resources and references on relevant topics.

Book excerpt: 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
Download or read book Mercury and Methylmercury Contamination of Terrestrial and Aquatic Ecosystems written by St ́ephane Gu ́edron and published by Mdpi AG. This book was released on 2021-11-09 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue aims to provide new insights into the issue of the mercury contamination of terrestrial and aquatic ecosystems. This ubiquitous contaminant has been used by humans for many years, resulting in global contamination. When this toxic contaminant is converted to methylmercury, it accumulates in trophic chains, which is a major issue for wildlife and human health. The nine articles contained within this Special Issue on ''Mercury and Methylmercury Contamination of Terrestrial and Aquatic Ecosystems'' endeavour to identify the historical evolution of Hg and MeHg levels in aquatic environments, and to evaluate the impact of current and historical human activities, such as mining, climate change, and soil erosion, on receptor ecosystems and food chains.
Download or read book Toxicological Effects of Methylmercury written by National Research Council and published by National Academies Press. This book was released on 2000-09-27 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
