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 2022-06-30 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document includes a pragmatic framework 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 used lead acid battery recycling (ULAB) 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. These guidelines focus on small-scale ULABs that are known to generate significant amounts of lead waste through the smelting process, as well as other metals including arsenic and cadmium. A primary concern with lead exposure is the documented association with neurodevelopmental outcomes in children as demonstrated by statistically significant reduced performance on a variety of cognitive tests. These associations are evident even in the youngest children, and toxicological and epidemiologic data indicate these effects have no threshold. Other potential exposures include arsenic and cadmium, and exposure to these contaminants is also associated with neurodevelopmental outcomes in children, as well as arsenicosis; bladder, lung, and skin cancers; and renal outcomes. The primary objective of this document is to guide research to assess the relationship between environmental contamination, exposures, and health outcomes related to a subset of contaminants originating from ULAB activities for particularly vulnerable populations (such as children) and the general population within a single household in the vicinity of ULAB sites in low- and middle-income countries. To achieve this objective, biomonitoring and health outcome data are linked to household survey and environmental data (for example, soil, dust, water, and agricultural products) 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 ULAB activities on local populations. The guidelines can also assist in building local capacity toconduct environmental assessments following a consistent methodology to facilitate comparability across ULAB sites in different geographic areas. Sampling strategies and methods are prioritized given information needs, resource availability, and other constraints or considerations. The document includes a number of supporting appendixes that provide additional resources and references on relevant topics. Data obtained following these recommendations can be used to support consistent, comparable, and standardized community risk and health impact assessments at contaminated sites in low- and middle-income countries. These data can also be used to support economic analyses and risk management decision-making for evaluating site cleanup and risk mitigation options in the most cost-effective and efficient manner. Following these recommendations will facilitate comparisons and meta-analyses across studies by standardizing data collection efforts at the community level.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.
