As EPA holds two days of hearings on its latest assessments of trichloroethylene (TCE), the chemical industry is pointing to newly acknowledged errors in a controversial study of the substance to bolster its opposition to two assessments, charging that the errors preclude adequate analysis and interpretation of study results needed to support a cardiac birth defects risk for TCE. The industry groups are pointing to errors that the authors of Paula D. Johnson's 2003 toxicology study - which showed evidence of heart malformations in the fetuses of pregnant laboratory mice exposed to TCE - acknowledged last April when they issued an erratum in the journal Environmental Health Perspectives acknowledging the study had misreported dates of when certain rodents were exposed to TCE.
