  • Title: Dichloroacetic acid and trichloroacetic acid increase chloroform toxicity.
    Author: Davis ME.
    Journal: J Toxicol Environ Health; 1992 Sep; 37(1):139-48. PubMed ID: 1522607.
    Abstract:
    Dichloro- and trichloroacetic acids (DCA and TCA) and chloroform are formed during chlorination disinfection of drinking water. The effects of DCA and TCA treatment on CHCl3 toxicity were assessed in these studies. Male and female rats were gavaged with DCA or TCA (0.92 and 2.45 mmol/kg administered 3 times over 24 h). Three hours after the last dose CHCl3 was injected ip (0.75 mg/kg). Male rats experienced some weight loss (15%) and slight increases of ALT and BUN, but there were no effects of either DCA or TCA on any of these responses. In females, CHCl3 increased plasma ALT and this response was greater (up to threefold) in the DCA group, compared to saline controls. Similarly, BUN was increased by CHCl3 and this was more severe (up to threefold) in both the DCA and TCA pretreated groups. These results show that CHCl3 toxicity is increased by DCA and TCA, and this effect is gender-specific, occurring only in females. DCA increases both liver and kidney toxicity, whereas TCA affects only kidney toxicity.
