Chlorine containing compounds were supplied as chlorinated hydrocarbons
, dry HCl gas in organic solvents, Cu (I and II) chlorides and iron (III) chlorides.
Several techniques exist to treat groundwater contaminated with petroleum and chlorinated hydrocarbons
The typical properties of chlorinated hydrocarbons
are given in Table 1.
reports that it has entered into contracts totaling $2,400,000 for the treatment of soils contaminated with chlorinated hydrocarbons
Solvents include aliphatic and chlorinated hydrocarbons
, esters, ketones, alcohols, gylcols, glycol ethers, cyclic or aromatic hydrocarbons, fluorocarbons and nitroparaffins.
Finally, to identify any organic compounds that have survived, we have to deal with oxychlorine compounds and possibly other strong oxidants in the sample which will react with and combust organic compounds to carbon dioxide and chlorinated hydrocarbons
when the samples are heated by SAM.
Flex-Lag Adhesives are also environmentally friendly, comprised of a polychloroprene rubber in a solvent base that is free of chlorinated hydrocarbons
are a group of chemicals that include pesticides such as DDT, solvents such as chloroform, polyvinyl chloride products, and others.
Altogen Labs also offers soil remediation services and development programs focused on other chemical contaminations besides crude oil, including remediation of soil with recalcitrant organic chemical spills including polycyclic aromatic hydrocarbons, petroleum, pesticides, herbicides, perchlorate, carbon tetrachloride, chloroform, acetone, benzene, toluene, xylenes, perchloroethylene, chlorofluorocarbon, aliphatic chlorinated hydrocarbons
, and other industrial and chemical manufacturing wastes and spills.
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.
