Michihiro Kamijima et al.
International archives of occupational and environmental health, 80(5), 357-370 (2006-11-16)
Workers exposed to trichloroethylene (TCE) rarely show severe generalized skin disorders and accompanying hepatitis which resemble drug hypersensitivities. The disorders are completely different from solvent-induced irritating contact dermatitis, and their serious consequences have become one of the critical occupational health
Cheryl Siegel Scott et al.
Environmental health perspectives, 114(9), 1471-1478 (2006-09-13)
A large body of epidemiologic evidence exists for exploring causal associations between cancer and trichloroethylene (TCE) exposure. The U.S. Environmental Protection Agency 2001 draft TCE health risk assessment concluded that epidemiologic studies, on the whole, support associations between TCE exposure

Journal of contaminant hydrology, 144(1), 108-121 (2012-12-19)
Column experiments and numerical simulations were conducted to evaluate the effects of Cr(VI) and dissolved CaCO(3) on the iron reactivity towards trichloroethene (TCE) and Cr(VI) reduction. Column experiments included measurements of iron corrosion potential and characterization of surface film composition

Occupational and environmental medicine, 70(11), 795-802 (2013-07-25)
We evaluated the association between occupational exposure to trichloroethylene (TCE) and risk of non-Hodgkin lymphoma (NHL) in a pooled analysis of four international case-control studies. Overall, the pooled study population included 3788 NHL cases and 4279 controls. Risk of NHL
Luoping Zhang et al.
Carcinogenesis, 34(4), 799-802 (2013-01-02)
Trichloroethylene (TCE) has been associated with a variety of immunotoxic effects and may be associated with an increased risk of non-Hodgkin lymphoma (NHL). Altered serum immunoglobulin (Ig) levels have been reported in NHL patients and in animals exposed to TCE.
