Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: No life cycle assessment (LCA) of artisanal and small-scale mining activities (A&Sma) has been identified as of today, and there are limited studies about large-scale mining and alluvial mining. The A&Sma are relevant economic sectors in countries with large reserves of mineral resources. Gold is the most representative metal mined with these practices and is used not only in jewelry but also in several electronics appliances. South America accounted for 17% of the total worldwide gold extraction in 2005; A&Sma occurred mostly in Colombia, Peru, and Brazil. The aim of this study is to estimate environmental indicators using methodologies for life cycle inventories (LCIs) in one of the two largest producers of gold through A&Sma in South America, Peru, and to discuss possible indicators for A&Sma in South America. Different functional units were used for each case study, as gold with different concentrations was produced and it was not possible to collect data for downstream processes for both bases. The product systems start in the mining and end with the gold production. Data were collected in two mining sites and, later on, related to the functional units. The results showed the amount of energy and water consumed as well as mercury used and released, carbon dioxide (CO) emissions, and solid wastes for each type of gold produced.
