Abstract:

Levels of six non-dioxin-like indicator PCBs in 36 composite samples of agricultural crops, related by-products and foodstuffs were pooled from a total of 938 individual samples collected in Serbia in 2002 and 2004. After extraction and cleanup, PCBs were determined by capillary GC using ECD. The highest total PCB levels were found in dried sugar beet pulp (2.89 ng g-1 whole weight (ww)) and crude sunflower oil (1.83 ng g-1 lipid), while the lowest levels were found in molasses (0.05 ng g-1 ww). The calculated daily intake of PCBs for the crop products included in this study were compared with the maximum permissible risk (MPR) level established by the Dutch National Institute for Public Health and the Environment. Cereal products (flour, bread, pastry, pasta, cookies) were made a relatively large contribution (23% of MPR), while sugar (2% of MPR) and oil (4% of MPR) made a low and fairly uniform contribution to intake. The levels and intake of PCBs in Serbia were compared with data from other recent international surveys.
