چکیده
Trichloroethylene is a major nonflammable industrial solvent. In 2011, the estimated capacity of the commercial production of trichloroethylene in the United States was 270 million pounds. Historically, the most important use of trichloroethylene has been vapor degreasing of metal parts. This use has declined over the past decade due to increased environmental regulations governing trichloroethylene emissions. At the same time, trichloroethylene has found increasing use as a feedstock for the refrigerant, HFC-134a. Trichloroethylene is also widely used as a solvent for extraction, waterless drying and finishing, and as a general purpose solvent in adhesives, lubricants, paints, varnishes, paint strippers, pesticides, and cold metal cleaners.

1,1,2,2-Tetrachloroethane is currently used as a chemical intermediate in the production of chlorinated hydrocarbons. In the past, this substance was used as an industrial solvent and extractant and was even a component of a few pesticide formulations; however, its manufacture and use as an end-product appears to have ceased in the United States. Present sources of 1,1,2,2-tetrachloroethane are...
متن کاملOptimizing electrocoagulation and electro-Fenton process for treating car wash wastewater
Background: Car wash wastewater contains several contaminants such as organic matter, oil, grease, detergents and phosphates, all of which are harmful for the environment. In this study, the application of electrocoagulation (EC) to treat car wash wastewater has been studied, and the operating parameters optimized. The electro-Fenton (EF) for further contaminant removal was also investigated. ...
متن کاملAir toxics and birth defects: a Bayesian hierarchical approach to evaluate multiple pollutants and spina bifida
BACKGROUND While there is evidence that maternal exposure to benzene is associated with spina bifida in offspring, to our knowledge there have been no assessments to evaluate the role of multiple hazardous air pollutants (HAPs) simultaneously on the risk of this relatively common birth defect. In the current study, we evaluated the association between maternal exposure to HAPs identified by the...

Hexachlorocyclohexane (HCH) is a synthetic chemical consisting of eight isomers. Only four of these isomers—α-HCH, β-HCH, γ-HCH, and δ-HCH—are of commercial significance. γ-HCH, commonly referred to as lindane, is used as seed treatment for barley, corn, oats, rye, sorghum, and wheat. It is also used in very small quantities as a prescription medication for the treatment of scabies and head lic...
