EPA's PV29 Assessment Likely To Test Reformed TSCA's Data Standards

摘要

EPA's recently released draft assessment of pigment violet 29 (PV29), the first such study of an existing chemical under the revised Toxic Substances Control Act (TSCA), is likely to pose a test of the new law's data standards as environmentalists and others doubt the agency has enough information on which to base its conclusion that the substance does not pose an "unreasonable risk." In their comments on EPA's problem formulation document on PV29, environmental.,academic and public health groups urged EPA last August to require new toxicity tests of the chemical.,arguing that EPA had insufficient information to conduct an assessment of adequate quality to meet the revised TSCA's standards.
