Procjena izloženosti metomilu odlučujući je korak u kvantitativnoj ocjeni rizika

Methomyl, methyl N-[[(methylamlno)carbonyl]oxy]etharmidothioate is a carbamate insecticide with anticholinesterase activity. As a broad spectrum insecticide, it is one of the most frequently used pesticides in tangerine orchards in Thailand. Although methomyl is said to be rapidly eliminated from experimental animals (1) high incidence of acute poisonings was reported among patients occupationally exposed to a powder formulation of methomyl (2, 3). In this passive dosimetry study of tangerine growers, during mixing and overhead spraying of a 90% powder formulation of methomyl, ocular and nasal exposure was measured. Exposure data are discussed in terms of the "potentially absorbed" or "internal dose".Metomil, metil N-[[(metilamino)karbonil]oksi]etarmidotioat je karbamatni insekticid s antikolinesteraznim djelovanjem. Kao insekticid širokog spektra nalazio se među pesticidima koji su najviše upotrebljavani u voćnjacima mandarinki u Tajlandu. Premda je na osnovi eksperimenata na životinjama poznato da se metomil brzo izlučuje, ustanovljena je visoka učestalost akutnih trovanja medu ljudima profesionalno izloženima praškastoj formulaciji metomila. U ovoj pasivnoj dozimetrijskoj studiji mjerena je izložonost putem očiju i nosa uzgajivača mandarinki tijekom miješanja i prskanja 90% praškaste formulacije metomila. 0 podacima se raspravlja u smislu eventualno apsorbirane ili interne doze
