Magnitude and decline of pesticide co-formulant residues in vegetables and fruits: results from field trials compared to estimated values.

ABSTRACT:

Background

The application of plant protection products (PPPs) leads to the formation of residues in treated crops. Even though PPPs contain considerable amounts of co-formulants, regulation and monitoring of residues normally focus on the active substances (a.s.) only. For our study we selected four commonly used co-formulants (three anionic surfactants and one organic solvent) and investigated the formation and decline of residues in vegetables and apples under field conditions. The aims were to characterize the behavior of co-formulant residues on crops and to provide a basis for future investigations on consumer exposure.

Results

The development of robust and sensitive analytical methods allowed the quantification of residues in the low μg/kg-level. After treatment with
