Several chlorinated hydrocarbons are first dechlorinated microbiologically and then metabolized.
The author notes six factors that have contributed to these improvements: advances in pesticide chemistry and toxicology, the banning of many chlorinated hydrocarbons, the development of new biochemical targets, increased reliance on genetically modified crops that has reduced the amount and variety of pesticides applied, an emphasis on biodegradability and environmental protection, and integrated pest-and pesticide-management systems.
Among the topics are spatial and temporal trends of polybrominated diphenyl ethers, the environmental contamination status of polychlorinated biphenyls in China, chlorinated hydrocarbons in animal tissues and products of animal origin from Poland, contamination profiles and temporal trends of POC in oysters from the Gulf of Mexico, and the contamination profile and temporal trends of persistent organic pollutants in Antarctic biota.
In regulating trichoroethylene and other chlorinated hydrocarbons, the EPA assumed that animal data are predictive for humans and also extrapolated from a high dose to the much smaller doses in most situations, and tried to regulate at a risk level on 1:1 million in a lifetime, or about 1:70 million per year, pessimistically calculated.
com, increased worldwide travel and the rising popularity of secondhand goods may be factors in the resurgence of bed bugs, but the most likely reason is our rejection of DDT and other harsh insecticides composed of chlorinated hydrocarbons.
According to Larry Pinto, author of The Techletter, a leading information source for the pest control industry, increased worldwide travel and the rising popularity of second-hand goods may be factors in the resurgence of bed bugs, but the most likely reason is our rejection of DDT and other harsh insecticides composed of chlorinated hydrocarbons.
