Resumo: | Residues of the insecticide malathion applied to stored maize grains were determined in the laboratory by means of radiotracer techniques, which permitted the discrimination between surface residues, solvent extracted residues and bound residues. Results indicated that with time, the amount of bound and extractable residues is enhanced inside the grains from 8.9% to 14.7% while the surface residues progressively diminishes in the same period, reaching to about 50% of the applied concentration. |

Em grãos de milho armazenado em laboratório e pulverizados com 40 µCi/10 ml de malation-14C determinou-se por meio de técnicas radiométricas os resíduos de superfície, extraíveis e ligados. Os resultados indicaram que com o tempo a quantidade de resíduos aumenta no interior dos grãos passando de 8,9% a 14,7%, enquanto que os resíduos de superfície diminuem, progressivamente, no mesmo período, até atingirem 50% da concentração aplicada.
