Research output: Contribution to journalArticle


Fourteen organophosphorus esters (OPs) were evaluated for their potential to cause organophosphorus ester induced delayed neurotoxicity (OPIDN) when administered dermally and/or orally to white leghorn hens. The compounds were chlorpyrifos, DEF, dichlorvos, dimethoate, EPN, ethoprop, fenthion, isofenphos, leptophos, merphos, ronnel, tetrachlorvinphos, terbufos, and trichlorfon DEF.
