Interim Reregistration Eligibility Decision for Naled (Includes Naled Facts)

摘要

Naled, first registered in 1959 in the United States, is an organophosphate (OP) insecticide used on a variety of insects. AMVAC purchased naled from Valent in November of 1998. The Agency issued a Registration Standard for naled in September, 1983 (NTIS No. PB-84- 158989), which required certain data to support the registered uses. In November, 1991, the Agency issued a Data Call-In for naled requiring certain ecological effects, and occupational/residential exposure data. Additional occupational and residential exposure data were called in during 1993. In 1995, naled was also included in a Data Call-In for all chemicals applied to turf, as well as the DCI for exposure data related to worker reentry into agricultural fields. Developmental neurotoxicity data has also been required of OP insecticides, including naled. The United States Environmental Protection Agency (EPA) is issuing interim risk management decisions for the pesticide naled in this document, based on human and ecological risk assessments conducted by EPA and a review of public comments on the revised risk assessments. The decisions outlined in this document do not include the final tolerance reassessment decision for naled, since that decision will be made following consideration of the cumulative risks for all organophosphate (OP) pesticides, including an assessment of the naled metabolite, dichlorvos (DDVP). However, some tolerance actions for naled will be undertaken prior to completion of the final tolerance reassessment, including lowering of tolerances, changing definitions, and other administrative actions. Raising or establishing new tolerances will be deferred until after cumulative risks are considered. The Agency may need to pursue further risk management measures for naled once the cumulative risks are considered.
