Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the induction mechanism of imposex caused by organotin compounds in gastropods, as well as fundamental information on the physiology and biochemistry of reproduction in mollusks. Are the sex hormones of gastropod mollusks vertebrate-type steroids, or neuropeptides? What about lipid disturbance and membrane toxicity due to organotin compounds? The book also discusses the latest findings on the role of nuclear receptors, such as retinoid X receptor (RXR), retinoic acid receptor (RAR) and peroxisome proliferator-activated receptor (PPAR), in the development of imposex in gastropods. Further, it describes the current state of contamination by organotins in the marine environment and gastropod imposex, with a special focus on Europe and Asia, introduces readers to analytical techniques for organotin compounds, and assesses the contamination and adverse effects of alternatives to organotin-based antifouling paints. Imposex, a superimposition of male genital tracts, such as penis and vas deferens, on female gastropod mollusks, is known as a typical phenomenon or consequence of endocrine disruption in wildlife. Imposex is typically induced by very low concentrations of organotin compounds, such as tributyltin (TBT) and triphenyltin (TPhT) from antifouling paints on ships and fishing nets. Reproductive failure may be brought about in severely affected stages of imposex, resulting in population decline and/or mass extinction. Thus, gastropod imposex has been recognized as a critical environmental pollution issue. Although gastropod imposex is also highly interesting for the biological sciences because of its acquired pseudohermaphroditism and/or sex change by certain chemicals, such as TBT and TPhT, the mechanism that induces the development of imposex remains unclear, possibly due to our limited understanding of the endocrinology of gastropod mollusks. This book offers a useful guide for professionals and students interested in the fields of aquatic biology, invertebrate physiology, ecotoxicology and environmental science.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation. Organotins are widespread contaminants especially of water environments. Their chemically versatile structure makes organotin compounds able to bind to a variety of biomolecules thus widely affecting biological functions. Trisubstituted molecules, namely tributyltin (TBT) and triphenyltin (TPhT), have been widely employed in antifouling paints and are also exploited as plastic stabilizers that unfortunately cause harmful biological effects. Persistent bioaccumulation has resulted in organotins becoming a significant environmental threat. Chapter by chapter, the biological and biochemical effects of organotins are unravelled in this e-book by a careful analysis of the most recent findings with special focus on contaminant action mechanisms at cellular and molecular level. The e-book provides an intriguing insight into the molecular mechanisms involved in organotin toxicology thus serving as a useful reference to biochemists, biologists, ecotoxicologists and life science students.

This book was released on 19?? with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the readily available literature on the biological fate and effects of organotin compounds in the marine environment, with particular interest in tin compounds of potential use to the U.S. Navy in antifouling paints or hull coatings. The review distinguishes among organotin occurrence and distribution, bioaccumulation, chemical and biological degradation, biomethylation, effects of exposure, and mode of toxic action. The assembled information base is reviewed with sufficient depth to permit a reasonable determination of their adequacy for assessment and prediction of environmental impacts. A recommended program of research is also presented for purposes of generating enumerated data deficiencies. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: single toxicant before it, yet one that has now been brought under effective control-at least in estuaries and the nearshore environment. The problem with TBT and its cause was first recognized in France, then in the United Kingdom and the United States of America; and in these and other countries legislation is now in place (see Abel, Chapter 2; Champ and Wade, Chapter 3), but in many countries the hazard is only now being identified. This volume has the important function of making available to all a summary of the results of work on TBT and the main conclusions. It will help to minimize the duplication of research and speed the introduction of legislation around the world to control organotin pollution. It is the more valuable because research on TBT has often been published in less accessible journals and symposium proceedings. This volume brings together accounts of these findings by the major contributors to the TBT story, providing the most comprehensive account to date. The TBT problem has proved to be instructive in a number of different ways beyond the bounds of the specific issue (Stebbing, 1985). Most important is that TBT can be seen as a challenge to monitoring systems for nearshore waters, by which it can be judged how effective monitoring has been in fulfilling its purpose, and what improvements should be made. Most instructive was the time it took to bring TBT under control.

Download or read book Interaction of Organotin Compounds with Model and Biological Membranes written by Enrico Bertoli and published by . This book was released on 1993 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organotin compounds find extensive commercial applications in three main areas: as heat stabilizers for PVC polymers, as industrial and agricultural biocides, and as industrial catalysts for a variety of chemical reactions. The widespread use of tributyltins (TBTs) has necessitated studies aimed at a better understanding of the effects of exposure of TBT compounds to mammals. The cellular and biological effects of TBTs have been examined in order to elucidate their molecular mode of action, as the plasma membrance can be considered to be the first target site of a cell. In particular, TBTs are potent membrane toxicants, their interaction with the constituent membrane. In general, the toxicity of TBTs is less than that of the dibutyltins, which in turn is less than that of monobutyltins; within a series of trialkyltin compounds, the lower homologues, trimethyltins and triethyltins.

Download or read book Trace Element Speciation for Environment Food and Health written by L Ebdon and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ongoing progress of science has shown that it is important for analytical scientists to determine not only the presence of particular elements, but also their species. There are many fields where this is applicable, and where there are a number of topics to be addressed. Developing separation and measurement systems for the many element species has tested the resourcefulness of analytical chemists over recent decades. A product of the EU sponsored Speciation 21 Network, this book presents a detailed review of the state-of-the-art of speciation issues in the occupational health, food and environment sectors, along with the main conclusions arising from discussions held during expert meetings. Topics covered include mercury and organotin compounds in the environment; factors affecting the health of workers; the importance of speciation of trace elements for health, and subsequent metabolism in the body; analytical methodologies; risk assessment; and legislation. Trace Element Speciation for Environment, Food and Health provides an insight into applied research in the speciation field and how it has become so important in all the fields represented. With its comprehensive coverage, it will be of particular interest to researchers in industry and academia, as well as government agencies and legislative bodies.

Available in PDF, EPUB and Kindle. Book excerpt: However the major toxic effects of triorganotin compounds are probably due to inhibition of the F-type H+-translocating ATPases of mithochondria, chloroplasts and bacteria which are produced by the organotin binding to the F component of these enzymes and thereby blocking proton H+ translocation. The Pand V type H+-ATPases are less sensitive as are other cation-translocating ATPases. The F-type H+-ATPases exhibit differential sensitivity to triorganotin compounds; the mammalian mitochondrial ATPases are potently inhibited by short-chain triorganotin whereas the chloroplast ATPases are more sensitive to highly hydrophobic organotins such as triphenyltins.
