Book excerpt: Kepone entered the James River estuary from point sources of production and through runoff from unauthorized disposal sites in the vicinity of Hopewell, Virginia. The total quantity of Kepone released to the river is not known, however, about 1.5 x 106 kg were produced between 1966 and 1975. At present we estimate that 30,000 kg reside in contaminated sediments of the estuary. Bed sediments are contaminated from the source at Hopewell to Hampton Roads, a distance of 88 kilometers. Patterns of contamination vary with sediment type and distance from the source. Major Kepone sinks exist in the Jamestown - Dancing Point reach and in Burwell Bay. Sediments from these zones are generally finer-grained and more enriched in organic matter than elsewhere and these zones are sites of relatively high sediment accumulation and fast deposition. This extensive contamination of the river sediments by Kepone presents problems for managers having to make decisions on dredging actions in the river. The most important questions which need to be answered concerning dredging activities are: 1) Will dredging result in significant quantities of Kepone being released to the environment? 2) Will the releases spread the contamination or result in increased bioaccumulation of Kepone in organisms? 3) Will the spoil disposal methods release Kepone to the marine environment or ground water?

Available in PDF, EPUB and Kindle. Book excerpt: In 1975 workers at Life Science Products, a small makeshift pesticide factory in Hopewell, Virginia, became ill after exposure to Kepone, the brand name for the pesticide chlordecone. They made the poison under contract for a much larger Hopewell company, Allied Chemical. Life Science workers had been breathing in the dust for more than a year. Ingestion of the chemical made their bodies seize and shake. News of ill workers eventually led to the discovery of widespread environmental contamination of the nearby James River and the landscape of the small, working-class city. Not only had Life Science dumped the chemical, but so had Allied when the company manufactured it in the 1960s and early 1970s. The resulting toxic impact was not only on the city of Hopewell but also on the faraway fields where Kepone was used as an insecticide. Aspects of this environmental tragedy are all too common: corporate avarice, ignorance, and regulatory failure combined with race and geography to determine toxicity and shape the response. But the Kepone story also contains some surprising medical, legal, and political moments amid the disaster. With Poison Powder, Gregory S. Wilson explores the conditions that put the Kepone factory and the workers there in the first place and the effects of the poison on the people and natural world long after 1975. Although the manufacture and use of Kepone is now banned by the Environmental Protection Agency, organochlorines have long half-lives, and these toxic compounds and their residues still remain in the environment.
Download or read book Marine Pollution written by Tobias N. Hofer and published by Nova Publishers. This book was released on 2008 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine pollution is the harmful effect caused by the entry into the ocean of chemicals or particles. An associated problem is that many potentially toxic chemical's adhere to tiny particles which are then taken up by plankton and benthos animals, most of which are either deposit or filter feeders, concentrating upward within ocean food chains. Also, because most animal feeds contain high fish meal and fish oil content, toxins can be found a few weeks later in commonly consumed food items derived from livestock and animal husbandry such as meat, eggs, milk, butter and margarine. One common path of entry by contaminants to the sea are rivers. Many particles combine chemically in a manner highly depletive of oxygen, causing estuaries to become anoxic. This book presents the latest research in the field from around the world.

Available in PDF, EPUB and Kindle. Book excerpt: The pervasive, widespread problem of contaminated marine sediments is an environmental issue of national importance, arising from decades of intentionally and unintentionally using coastal waters for waste disposal. This book examines the extent and significance of the problem, reviews clean-up and remediation technologies, assesses alternative management strategies, identifies research and development needs, and presents the committee's major findings and recommendations. Five case studies examine different ways in which a variety of sediment contamination problems are being handled.

Download or read book Kepone in the James River Estuary written by Michael A. Unger and published by . This book was released on 2017 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: In late 1975, a manufacturing facility in Hopewell, VA had not only exposed workers to the chlorinated pesticide, Kepone, but had also severely contaminated the James River estuary. To assess the potential risk to the public, Virginia initiated a finfish-monitoring program in late 1975. Over the next 40 years over 13,000 samples were collected from the James River and Chesapeake Bay and analyzed for Kepone. Kepone production was eventually banned worldwide. The average Kepone concentrations found in most species began falling when the production of Kepone ended, but the averages remained over the action limit of 0.3 mgkg-1 until the early 1980s. By 1988, few fish contained average Kepone concentrations greater than the action limit. Kepone was still detected (>0.01 mgkg-1 wet weight) in the majority of white perch and striped bass samples taken from the James River in 2009 and a fish consumption advisory is still in effect over forty years after the source of contamination was removed. Due to state budget cuts, monitoring of Kepone has not been conducted since 2009. As part of its 40th Anniversary, the Virginia Environmental Endowment -- which was established as part of the Kepone pollution court settlement in 1977 -- requested that VIMS conduct an updated study of the current levels of Kepone in the James River.

Book excerpt: Preliminary studies conducted by personnel of the Allied Chemical Corporation at Morristown, N. J. suggested that coa] would be used to adsorb Kepone from an aquatic substrate. .The possibility of using coal to bind Kepone contaminating the natural environment indicated further preliminary exploration of the matter. The Virginia Institute of Marine Science undertook a laboratory study with oysters under contract with the Allied Chemical Corp. to explore that possibility. Lignite was mixd on a 1:10 dry-weight ratio with sediments contaminated with Kepone.

Download or read book Ecotoxicology Problems and Approaches written by Simon A. Levin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is the science that seeks to predict the impacts of chemi cals upon ecosystems. This involves describing and predicting ecological changes ensuing from a variety of human activities that involve release of xenobiotic and other chemicals to the environment. A fundamental principle of ecotoxicology is embodied in the notion of change. Ecosystems themselves are constantly changing due to natural processes, and it is a challenge to distinguish the effects of anthropogenic activities against this background of fluctuations in the natural world. With the frustratingly large, diverse, and ever-emerging sphere of envi ronmental problems that ecotoxicology must address, the approaches to individual problems also must vary. In part, as a consequence, there is no established protocol for application of the science to environmental prob lem-solving. The conceptual and methodological bases for ecotoxicology are, how ever, in their infancy, and thus still growing with new experiences. In deed, the only robust generalization for research on different ecosystems and different chemical stresses seems to be a recognition of the necessity of an ecosystem perspective as focus for assessment. This ecosystem basis for ecotoxicology was the major theme of a previous pUblication by the Ecosystems Research Center at Cornell University, a special issue of Environmental Management (Levin et al. 1984). With that effort, we also recognized an additional necessity: there should be a continued develop ment of methods and expanded recognition of issues for ecotoxicology and for the associated endeavor of environmental management.
