Residues of aldicarb in coconut

Determinations were made of aldicarb residues in coconut cultivated on soils containing aldicarb granules. The quantitative estimations in coconut milk and kernel were made by colorimetry and gas-liquid chromatography; samples harvested at various times were analysed. Residues in samples of kernel did not exceed 0.04 mg kg^?1 (total toxic aldicarb residues), while milk samples showed no detectable residues.
