Pesticide residues in samples of apples, lettuce and potatoes from integrated pest management in Slovenia from 2005-2009 | Ostanki pesticidov v vzorcih jabolk, solate in krompirja v integrirani pridelavi v Sloveniji v letih 2005-2009

英语. In the period from 2005 to 2009 225 samples of apples, lettuce and potatoes from Slovene producers included in integrated pest management (IPM) were analysed for plant protection product (PPP) residues. The samples were analysed for the presence of more than 200 different active compounds using four analytical methods. In 38.7% of apple samples residues were not detected, 58.6% of apple samples contained residues lower than or equal to Maximum Residue Levels (MRLs) while 2.7% of apple samples exceeded MRLs. In 84.6% of lettuce samples residues were not detected, 12.3% of lettuce samples contained residues lower than or equal to MRLs while 3.1% of lettuce samples exceeded MRLs. In 98.0% of potato samples residues were not detected, 2.0% of potato samples contained residues lower than or equal to MRLs and no potato samples exceeded MRLs. Multiple residues were found only in apples and lettuce. The trend observed during the years was the decrease of sample portion of samples containing multiple residues in apples from 2005 to 2008. The most frequently found active substance in apples and lettuce was dithiocarbamates. In potato only phosalone was found.

斯洛文尼亚语. V obdobju od 2005 do 2009 smo na ostanke fitofarmacevtskih sredstev (FFS) analizirali 225 vzorcev jabolk, solate in krompirja slovenskih proizvajalcev vključenih v integrirano pridelavo (IP). Vse vzorce smo analizirali s štirimi analitskimi metodami na prisotnost več kot 200 različnih aktivnih spojin. V 38,7% vzorcev jabolk ostankov nismo določili, 58,6% vzorcev jabolk je vsebovalo ostanke manjše ali enake maksimalnim dovoljenim količinam ostankov (MRL) medtem ko je 2,7% vzorcev jabolk preseglo MRL vrednosti. V 84.6% vzorcev solate ostankov nismo določili, 12,3% vzorcev solate je vsebovalo ostanke manjše ali enake MRL vrednostim medtem ko je 3,1% vzorcev solate preseglo MRL vrednosti. V 98,0% vzorcev krompirja ostankov nismo določili, 2,0% vzorcev krompirja je vsebovalo ostanke manjše ali enake MRL vrednostim in nobeden vzorec krompirja ni presegel MRL vrednosti. Ostanke dveh ali več aktivnih spojin smo določili le v jabolkih in solati. Trend, ki smo ga opazili tekom let je, da delež vzorcev, ki vsebujejo ostanke dveh ali več aktivnih spojin v jabolkih, pada od leta 2005 do 2008. Najpogosteje najdena aktivna snov v jabolkih in solati je ditiokarbamati. V krompirju smo določili le fosalon.
