MONITORING OF PESTICIDE RESIDUES IN AGRICULTURAL PRODUCTS IN THE YEARS 2003 AND 2004 IN SLOVENIA

Sa？etak Agricultural Institute of Slovenia was performing national monitoring for pesticide residues in agricultural products according to the Decree on Monitoring of Pesticides in Foodstuffs and in Agricultural Products (Offi cial Gazette of the Republic of Slovenia No. 13/99). Constant measurements are necessary due to intensive agricultural production and use of chemical substances for plant protection. Due to the nutrition characteristic for the Slovenians pesticide residues are monitored each year in the samples of potato, lettuce and apples; the choice of other agricultural products and active substances analysed are adapted to the guidelines indicated in the EU recommendations. In the years 2003 and 2004 we analysed the presence of pesticide residues in 361 samples of agricultural products: caulifl ower, head cabbage, grapes, apples, strawberries, potatoes, peppers, tomatoes, wheat and lettuce from eight different growing areas of Slovenia. All agricultural products were analysed in 2003 for the presence of 51 active substances and in 2004 for the presence of 57 active substances. The maximum residue level (MRL) was exceeded by 6.6 % samples inspected. Potato contributed a major share to this, since in 5.0 % of samples exceeded values of dithiocarbamate residues were determined, however, they were the only active substance found in potato. In 39.1 % of analysed samples residues lower than MRL were determined, in 54.3 % of samples residues were not found or they were below the level of detection method. The greatest number of pesticide residues which did not exceed MRLs was found in fruit, f. ex.: eight in apples and six in strawberries. Residues of dithiocarbamates were the most frequently found active substance in agricultural products
