EPA Evaluates Current Test Methods and NMDR
Jun 23rd
EPA has concluded that the agency’s current toxicity test methods are sufficient to determine chemicals’ hazards, despite finding in a just issued draft paper that exposure to some chemicals can result in unpredictable non-monotonic dose responses which some say can lead to effects that current testing does not detect. This EPA conclusion is stated in a new draft white paper entitled “State of the Science Evaluation: Nonmonotonic Dose Responses as They Apply to Estrogen, Androgen, and Thyroid Pathways and EPA Testing and Assessment Procedures.” This paper is available for review by clicking here.
