WOE Characterization Framework for WOE Characterization
D (Not classifiable as to human carcinogenicity) Guidelines for Carcinogen Risk Assessment (US EPA, 1986)
Carcinogenic potential cannot be determined Proposed Guidelines for Carcinogen Risk Assessment (US EPA, 1996)
Basis:
  • Under the current guidelines (U.S. EPA, 1986), chlorite is classified as Group D; not classifiable as to human carcinogenicity because of inadequate data in humans and animals. Under the draft Carcinogen Assessment Guidelines (U.S. EPA, 1996), the human carcinogenicity of chlorite cannot be determined because of a lack of human data and limitations in animal studies.
  • This may be a synopsis of the full weight-of-evidence narrative.
