1,3-Dichloropropene

1,3-dichloro-1-Propene (acd/name 4.0)

C3H4Cl2 (109.9690044)


1,3-Dichloropropene, also known as Telone or simply 1,3-D, is a colorless liquid with a sweet smell. It exists as a mixture of the geometric isomers cis-1,3-dichloropropene and trans-1,3-dichloropropene. It dissolves in water and evaporates easily. It is used mainly in farming as a pesticide, specifically as a preplant fumigant and nematicide. It widely used in the US and other countries, but in the process of being phased out in the European Union.

Trichloroethylene

Trichloroethylene (without epichlorohydrin)

C2HCl3 (129.9143836)


Trichloroethylene is a solvent and extractive in the manufacture of foods. One recent review of the epidemiology of kidney cancer rated cigarette smoking and obesity as more important risk factors for kidney cancer than exposure to solvents such as trichloroethylene. In contrast, the most recent overall assessment of human health risks associated with trichloroethylene states, "[t]here is concordance between animal and human studies, which supports the conclusion that trichloroethylene is a potential kidney carcinogen". The evidence appears to be less certain at this time regarding the relationship between humans and liver cancer observed in mice, with the NAS suggesting that low-level exposure might not represent a significant liver cancer risk in the general population. The chemical compound trichloroethylene is a chlorinated hydrocarbon commonly used as an industrial solvent. It is a clear non-flammable liquid with a sweet smell. The first known report of TCE in groundwater was given in 1949 by two English public chemists who described two separate instances of well contamination by industrial releases of TCE. Based on available federal and state surveys, between 9\\% to 34\\% of the drinking water supply sources tested in the U.S. may have some TCE contamination, though EPA has reported that most water supplies are in compliance with the Maximum Contaminant Level (MCL) of 5 ppb. In addition, a growing concern in recent years at sites with TCE contamination in soil or groundwater has been vapor intrusion in buildings, which has resulted in indoor air exposures, such is in a recent case in the McCook Field Neighborhood of Dayton, Ohio. Trichloroethylene has been detected in 852 Superfund sites across the United States, according to the Agency for Toxic Substances and Disease Registry (ATSDR). Under the Safe Drinking Water Act of 1974, and as amended annual water quality testing is required for all public drinking water distributors. The EPAS current guidelines for TCE can be found here. It should be noted that the EPAs table of "TCE Releases to Ground" is dated 1987 to 1993, thereby omitting one of the largest Superfund Cleanup sites in the nation, the NIBW in Scottsdale, Arizona. The TCE "released" here occurred prior to its appearance in the municipal drinking wells in 1982. This reaction can be catalyzed by a variety of substances. The most commonly used catalyst is a mixture of potassium chloride and aluminum chloride. However, various forms of porous carbon can also be used. This reaction produces tetrachloroethylene as a byproduct, and depending on the amount of chlorine fed to the reaction, tetrachloroethylene can even be the major product. Typically, trichloroethylene and tetrachloroethylene are collected together and then separated by distillation.Trichloroethylene: Parkinsonism and complex 1 mitochondrial neurotoxicity).

C10H5Cl9 (439.75880000000006)


trans-Nonachlor os one of the most common chlordane-related environmental contaminants. It is an organochlorine chemical, a class largely banned in the U.S. that builds up in the body over time, linked to cancer and reproductive harm. It is a bioaccumulating component of the pesticide chlordane, which can be detected in various environmental biota and in humans. Some studies also show that there is a dose-response relations between serum cencetrations of trans-nonachlor and the prevalence of diabetes.
