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
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.
