Most of the early studies focused on the legacy chiral pesticides, such as α-HCH, chlordane, and o,p′-DDT. In this article, the environmental enantioselective consequences, including aquatic toxicity, cell toxicity, endocrine disruption and carcinogenicity of some chiral pesticides, are reviewed. Thus, this ACS Symposium book will generate many new ideas from interested readers and inform them of useful techniques for experimental exploration of the somewhat exotic, but important, area of chiral chemistry of tonyasgaapartments.com: A.

An Introduction to Pesticide Chirality and the Consequences of Stereoselectivity --Section: Occurrences --Chiral chlordane components in environmental matrices --Comparison of the enantiomer distribution of chiral organochlorine contaminants in captive West Greenland sled dogs and polar bears from Baffin Bay --Section: Analysis. Anthropogenic chemicals, including pesticides, are a major source of contamination and pollution in the environment. Pesticides have many positive uses: increased food production, decreased damage to crops and structures, reduced disease vector populations, and more. Nevertheless, pesticide exposure can pose risks to humans and the environment, so various mitigation strategies are exercised to.
Search Tips. Phrase Searching You can use double quotes to search for a series of words in a particular order. For example, "World war II" (with quotes) will give more precise results than World war II (without quotes). Wildcard Searching If you want to search for multiple variations of a word, you can substitute a special symbol (called a "wildcard") for one or more letters. Chiral pesticides may differ markedly in their environmental fate, bioavailability and toxicity. A number of reports have shown that chiral pesticides may cause enantioselective toxicities to aquatic organisms. Therefore, there may be up to 3 chiral carbon atoms in pyrethroid pesticides, and there may be 2,4 or 8 chiral isomers (Table 2) and all the enantiomer are greatly different in their biological activities. The representative stereo-structures of pyrethroids are shown in Figure 2. The pollution of racemic mixtures has been long regarded as a Cited by: 9. The study is aiming to present the fate of chiral pesticides, the different behaviour of these optic active isomers in the environment and their ecotoxicological effects, as well as separation.
Chiral pesticides are ubiquitous in the aquatic environment, and their enantioselectivities in aquatic toxicity are known to be complicated. The difference in enantioselective effects between enantiomers may sometimes differ by approximately fold or more, which makes it important to incorporate enantioselective effects into the risk assessment of chiral pesticides. The importance of stereochemistry for medicinal chemistry and pharmacology is well recognized and the dissimilar behavior of enantiomers is fully documented. Regarding the environment, the significance is equivalent since enantiomers of chiral organic pollutants can also differ in biodegradation processes and fate, as well as in tonyasgaapartments.com by: Chiral Pesticides: Stereoselectivity and Its Consequences ACS Symposium Series: tonyasgaapartments.com: A.
