Abstract
In the year 2007, 210 apple, cereal, cherry, head cabbage, leek, lettuce, peach, potato, strawberry and tomato samples from Slovene producers were analysed for pesticide residues. The samples were analysed for the presence of 118 different active compounds using four analytical methods. In four samples (1.9%) exceeded maximum residue levels (MRLs) were determined, which is better than the results obtained at the monitoring of pesticide residues in the products of plant origin in the European union, Norway, Iceland and Liechtenstein in 2005 (4.9%). Trends which can be observed through the years are the following: the highest number of active compounds are found in fruit, lower MRL exceedances were observed during the years, and the number of active substances found in one sample has increased.
