Triphenyltin Hydroxide; Proposed Determination To Terminate Special Review

This Notice sets forth EPA's preliminary determination regarding the continued registration of pesticide products containing triphenyltin hydroxide (TPTH) and sets forth the Agency's assessment of the risks and benefits associated with pesticidal uses of TPTH. On January 9, 1985, the Agency issued a Notice of Special Review of pesticide products containing triphenyltin hydroxide based on developmental toxicity (teratogenicity) concerns (50 FR 1107). Although not a subject of the Special Review, the Agency also cited concerns for reproductive toxicity, carcinogenicity, immunotoxicity, inhalation toxicity and adverse effects to non-target organisms in the Position Document 1. Due to voluntary actions by the registrants that have reduced worker exposure to TPTH, as well as additional data that refine the risk assessment, EPA has determined that the risks of using TPTH are substantially lower than when the Special Review was initiated in 1985. This Notice proposes to terminate the triphenyltin hydroxide Special Review based on the Agency's determination that the benefits of TPTH use outweigh the risks.
