Available in PDF, EPUB and Kindle. Book excerpt: Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.

Download or read book Transport and Fate of Polybrominated Diphenyl Ethers in the Baltic and Arctic Regions written by Nordic Council of Ministers and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decades, concern has been raised regarding the use of polybrominated diphenyl ethers (PBDEs) due to its increased environmental occurrence and its possible toxicological impact in humans and wildlife. As a result, two of the commercial PBDE products have recently been banned within the EU, while the use of the third product (DecaBDE) is still approved. A dynamic, fugacity-based, regional multimedia fate and transport model (POPCYCLING-Baltic) has been used to assess the historical behaviour and the potential future fate of polybrominated diphenyl ethers (PBDEs), exemplifying different emission scenarios following the introduction of restricting measures. The past, current and future consumption and emission of PBDEs were estimated, and the environmental fate of individual compounds was modelled. The possible impact on the Arctic region is also discussed. Uncertainties in the estimates and data gaps were identified

Download or read book Persistent Organic Pollutants written by Stuart Harrad and published by John Wiley & Sons. This book was released on 2009-11-19 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Persistent Organic Pollutants (POPs) are toxic, resistant to degradation, bioaccumulative, and display wide spatial distribution. They accumulate in humans and wildlife, and have been linked to cancer, as well as reproductive and immunological disorders. In 2001 a global treaty on POPs was agreed, to minimise and ultimately eliminate the release of POPs into the environment. The Stockholm Convention lists 12 groups of chemicals, and as of late 2008, a further 12 chemicals are under consideration for inclusion. This book addresses all of these chemicals, but focuses particularly on currently listed POPs that are still of major concern (e.g. polychlorinated biphenyls - PCBs), as well as new and emerging POPs that have been the subject of an explosion of scientific interest in the last decade, i.e. brominated flame retardants (BFRs) and perfluorinated chemicals (PFCs). Other chapters address the challenges posed by the presence of POPs in the developing world; how the properties of chiral POPs can provide unique insights into their environmental sources, fate and behaviour; and issues arising from the presence of POPs in urban and indoor environments. Persistent Organic Pollutants provides a much-anticipated reference source for a wide audience including academics, industrial scientists and regulators.

Available in PDF, EPUB and Kindle. Book excerpt: Humans around the world are exposed to many potentially toxic compounds of both natural and anthropogenic origin. Industrial chemicals represent a large fraction of such compounds, some of which are now considered widespread environmental pollutants. One such class of compounds is polybrominated diphenyl ethers (PBDEs), a widely prevalent persistent organic pollutant spread largely by anthropogenic production and use of these chemicals as flame retardants in consumer products. The lipophilic nature of PBDEs, which are small halogenated organic molecules, allows them to accumulate in lipid-rich bodily tissues, including the brain. Due to the exposure kinetics of these compounds (detailed in Chapter 4 of this dissertation), cortical astrocytes and neurons are likely exposed in a region-specific manner. Concerningly, there is now a growing body of evidence epidemiologically linking PBDE exposure levels and incidences of behavioral deficits related to neurodevelopmental disorders (NDDs) in human children. NDDs include intellectual disability, attention deficit disorders, and autism spectrum disorders that are estimated to affect up to 15% of children in the United States. This association is supported by evidence from non-human animal studies that has established that exposures to several PBDEs affect learning. In an effort to understand the effects of exposures to these compounds, several major molecular and cellular mechanisms have been identified, including: disruption of calcium homeostasis, interference with hormonal signaling, cellular toxicity resulting from mitochondrial disruption and the production of reactive oxygen species, and a more recently emerging focus, disruption of epigenetic mechanisms. Despite much progress, there is not a clear understanding of how these identified effects of PBDE exposure are related to observed impacts on behavior and learning. In this dissertation, I first tested the hypothesis that the effects of neurodevelopmental PBDE exposures intersect with epigenetic regulation in embryonic cortical neurons, leading to the development and testing of a mechanistic hypothesis of intracellular signaling disruption caused by ortho-hydroxylated PBDE metabolites. I close by detailing a model of neurodevelopmental PBDE exposures that I combine with novel data presented here to generate hypotheses for future study. This body of work aims to be of value in continuing to build an understanding of the effects of PBDE exposures in the developing nervous system, how these exposures are related to observed behavioral deficits in animals, and generating insight regarding the interplay between genetic and environmental risk factors in neurodevelopmental disorders.
