Use of Tetrachlorvinphos Exposure Data from Human Research

This document provides a full explanation of EPA’s decision to rely on data from human research on tetrachlorvinphos (TCVP) exposure from pet collars. Relying on this data is crucial to EPA’s decision that more stringent regulatory restrictions are necessary to protect public health than could be justified without the data.

Publishing this document complies with EPA’s rule for protection of human subjects, specifically 40 CFR 26.1706(d).
