Pesticide residues in crops (2008).

摘要

A total of 1 332 samples of fresh fruit, vegetables and cultivated crops of Polish origin were analysed in 2008 in five laboratories of the Institute of Plant Protection-National Research Institute. The monitoring programme covered 47 commodities and 120 pesticides including some isomers and breakdown products. Residues of 46 pesticides, mainly fungicides (25), were detected in 26.5% of samples analysed. Percentage of the samples without pesticide residues was equal to 73.5%. The residues lower than MRLs contained 24.4% of samples analysed. Violations of MRLs were found in 2.1% of the samples. The usage of not approved pesticides were stated in 1.7% of the samples. Residues were detected in 54.9% of fruit samples especially in samples of apples (67%), raspberries (63%), sour cherries (48%), strawberries (50%). The samples of vegetables and cultivated crops were less contaminated. Residues of dithiocarbamates were most often detected, in 17.4% of the samples. Three further pesticides procymidone, linuron, captan were found in 5-8% of the samples, while the majority of the others in less than 1% of samples analysed.
