RESUMO

The carbamate aldicarb is an insecticide of frequent usage in agriculture and it has hight toxicity as a caracteristic. In Brasil aldicarb is comercialized ilegaly as a rodenticide, this lead to inumerous causes of intoxication in domestic animals. The present record developed a methodology in cromatographic detection of aldicarb in blood of dogs and cats. The samples were analized after aminopropil column separation by hight performance liquid cromatography, acoplished to an UV detector. The concentration of aldicarb used for linearity variated between 150 a 10.000 ng/mL, and the r2 value was 0,995. The detection limit was defined as 75 ng/mL for aldicarb technical standard and 150 ng/mL for the fortificated sample and the quantification limit as 150 ng/mL for both samples. The recovery for medium concentration of 2500 ng/mL, added to the blood samples, was 2.248 ± 316 ng/mL, being equivalence to 89% of added value. The recovery for low concentration of 150 ng/mL, added to the blood samples, was 101 ± 18 ng/mL, being equivalence to 68% of added value. The present results allowed to conclude that the methodology of identification of aldicarb in blood was adequated, and could be employed in the diagnosis of exogenous intoxication by aldicarb for dogs and cats
