Health and Environmental Effects Profile for Chlorthiophos
The Health and Environmental Effects Profile for Chlorthiophos was prepared to support listings of hazardous constituents of a wide range of waste streams under Section 3001 of the Resource Conservation and Recovery Act (RCRA) and to provide health-related limits for emergency actions under Section 101 of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Chlorthiophos has been determined to be a systemic toxicant. An Acceptable Daily Intake (ADI), for chlorthiophos is 0.8 microgram/kg/day for oral exposure. The Reportable Quantity (RQ) value of 1, 10, 100, 1000 or 500 pounds is used to determine the quantity of a hazardous substance for which notification is required in the event of a release as specified by CERCLA based on chronic toxicity. Existing data are insufficient to determine an RQ value.
