Research on the actual residues for acetamiprid, (E)-N1-[(6-chloro-3-pyridyl)methyl]-N2-cyano-N1-methylacetamidine (ATP) in crops and soils was performed using two analytical methods for determining the residues of ATP and its metabolites. One is the parent analytical method for ATP determination and the other is the common moiety method for ATP and its metabolites (its degradation products) determination in crops and soils. For soil, an individual analytical method for ATP and its degradation products determination was devised. Residue analyses of 8 crops to which water soluble concentrate was applied suggested that there were no remarkable difference in residue amounts obtained from both methods so that ATP made up most of the residue in crops, and its metabolites were negligible in amount. For granule application, residue amounts of ATP and its metabolites obtained from the common moiety method (4 crops) were less than limit of detection (LOD, 0.01ppm) or near the LOD level more than 60 days after treatment. In case of soil, ATP degraded very rapidly and the half life of ATP itself was 1-2 days after treatment in container and field soils, and that of ATP and its degradation products were from 15 to 30 days after treatment in both conditions.
