Download or read book Mercury in the Environment written by Michael S. Bank and published by Univ of California Press. This book was released on 2012-05-31 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis A Risk Assessment for Ingestion of Toxic Chemicals in Fish from Imperial Beach, California by : Mallory Arden Lushenko
Download or read book A Risk Assessment for Ingestion of Toxic Chemicals in Fish from Imperial Beach, California written by Mallory Arden Lushenko and published by . This book was released on 2010 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contamination of fish by heavy metals, chlorinated pesticides, and polychlorinated biphenyls (PCBs) can compromise the health of recreational and subsistence anglers consuming the fish they catch. This investigation quantified chemical contaminants in fish muscle and liver tissue samples and followed methods of the U.S. Environmental Protection Agency (EPA) to estimate the hazard indexes and cancer risks associated with consuming fish caught in the waters off the Imperial Beach Pier in Imperial Beach, California. Similar risk assessment studies have been performed for other areas of Southern California but no such investigations have been undertaken for Imperial Beach. All fish samples were donated by Imperial Beach Pier anglers participating in a fishing derby on August 30, 2008. A total of 8 fish samples (3 jacksmelt, 3 mackerel, 1 yellowfin croaker, 1 white croaker) were collected and frozen until they were transported to CRG Marine Laboratories, Inc. for analysis of chemical contaminants. Different instrumentation, per the U.S. EPA methodologies, was used for the specific analytes. A mean ingestion value of 31.2 g/day and a subsistence ingestion value of 142.2 g/day were used along with the mean and maximum concentrations, respectively, to estimate the risk values for each chemical contaminant in muscle tissue. The level of exposure resulting from the consumption of each chemical in the fish tissue was estimated in an average daily dose equation. For noncarcinogenic chemicals, the average daily dose was divided by the oral reference dose, as specified by the U.S. EPA, for each chemical to estimate the hazard index. Estimation of risk for carcinogenic chemicals was calculated by multiplying the average daily dose by the cancer potency factor, also designated by the U.S. EPA. Hazard indexes were calculated for organic arsenic, cadmium, chromium (VI), methylmercury, nickel, selenium, and zinc while cancer risk calculations were done for total chlordane, total DDT, individual PCB congeners detected, and total PCBs. All noncarcinogenic chemicals yielded hazard index (HI) values below 1.0, with the exception of mean and subsistence level ingestion of organic arsenic, with HI values of 1.031 and 8.103, respectively, and subsistence level ingestion of methylmercury, which had a HI of 1.424. Cancer risk calculations exceeding the U.S. EPA's acceptable risk level of 1 in 1,000,000 (or 10-6) included total chlordane at the subsistence level ingestion (1.780 x 10-6), total DDT at the mean ingestion level (7.184 x 10-6), and each PCB congener at the subsistence ingestion level (2.034 x 10-6). Inorganic arsenic at mean and subsistence ingestion levels (5.154 x 10-5 and 4.053 x 10-4, respectively), total DDT at the subsistence ingestion level (7.538 x 10-5), and total PCBs at mean and subsistence ingestion levels (1.159 x 10-5 and 5.290 x 10-5, respectively) all exceeded the U.S. EPA acceptable cancer risk as well as the California EPA's less stringent acceptable risk level of 1 in 100,000 (or 10-5). Regarding the risks of fish liver tissue consumption, the mean mass of the livers collected was 2.48 g and an assumption was made that 3 fish livers of this mass were consumed per week, yielding a mean daily intake value of 1.06 g/day. The presence of metals was not analyzed in liver tissue samples, thus only cancer risk calculations for detected chlorinated pesticides and PCB congeners were performed using the arithmetic mean chemical concentration found in the samples. Of all carcinogenic chemicals detected in the liver samples, only the total PCBs concentration yielded a cancer risk exceeding the U.S. EPA acceptable risk level, with a risk value of 2.804 x 10-6. Some of the chemicals studied, such as arsenic and mercury, occur naturally in the environment and present a "natural" risk because of their behavior in the marine environment. Due to their ban in the U.S. and decreased use in Mexico, the concentrations of the "legacy" pollutants, such as DDT andPCBs, should continue to decline to within de minimus levels over the next decade or two. The results of this study have shown that some of the chemicals analyzed exert a marginal level of unacceptable risk at present, particularly when consumed at subsistence levels; thus, it is important that continued research be conducted to better establish fish consumption data and to aid in the creation of accurate fish consumption guidelines for anglers on the Imperial Beach Pier.

Traditional ecological knowledge and tribal experience play a key role in developing future scientific solutions for adaptation to the impacts. The book explores climate-related issues for indigenous communities in the United States, including loss of traditional knowledge, forests and ecosystems, food security and traditional foods, as well as water, Arctic sea ice loss, permafrost thaw and relocation. The book also highlights how tribal communities and programs are responding to the changing environments. Fifty authors from tribal communities, academia, government agencies and NGOs contributed to the book. Previously published in Climatic Change, Volume 120, Issue 3, 2013.
Book Synopsis Variable Justice by : Catherine O'Neill

Book excerpt: This article begins with the observation that “[f]ish, especially salmon, are necessary for the survival of the Native peoples of the Pacific Northwest, both as individuals and as a people.” It considers conventional approaches to regulating contamination of the waters that support the fish on which these peoples depend, and finds that the narrow focus on human physical health fails fully to comprehend the multiple dimensions of the harm to these fishing peoples. Importantly, this focus fails to appreciate the cultural dimensions of the harm. The article examines health and environmental agencies' standard-setting practices and challenges their failure to account for Native Americans' unique fish consumption practices. In the process, this piece questions the hegemony of quantitative risk assessment in agencies' standard-setting efforts. It goes on to criticize the resulting standards and the justifications offered by agencies - and sanctioned by courts - for the “lower yet adequate” level of protection they afford Native American subpopulations relative to the general population. In so doing, it considers the role of science and judgment in environmental risk policy, explicating such technical concepts as “variability” and “uncertainty.” It clarifies that discussing degrees of "conservatism" makes sense only in connection with agencies' responses to uncertainty. In the case of responses to interindividual variability, it is not a matter of choosing among errors. Rather, it is a matter of deciding, with full knowledge, whom to protect. As such, these responses ought be discussed in terms of "protectiveness." Having laid this groundwork, the article argues for agencies' differential treatment of Native American subpopulations from both a normative and doctrinal standpoint. Relevant normative commitments include respect for cultural integrity, equality and just process. Relevant legal obligations include treaties, the federal trust responsibility, and civil rights legislation. Finally, the article concludes with recommendations that agencies and tribes might consider, in consultation, as they engage in the process of environmental standard-setting.
