Technical Briefing on the Preliminary Organophosphate Pesticide Cumulative Risk Assessment

EPA is announcing a public technical briefing on January 15, 2002, to discuss the exposure methodologies proposed for use in the organophosphate (OP) cumulative risk assessment for food, drinking water, and residential exposures. The briefing will provide the public with an explanation in non-technical terms of the proposed exposure methodologies. In addition, the briefing will cover how the computer software model calculates and combines these exposure estimates. This briefing follows the August 22, 2001, briefing on the hazard portion of the assessment, the October 3, 2001, briefing on the water exposure methodology, and the November 15, 2001, briefing on the food and residential methodologies. This technical briefing will complete the background briefings on the proposed OP cumulative risk assessment methodology.
