  We analysed the raw materials in various food products, including additives, carrier solvents and end product for several selected organic pollutants. We analysed these food products for the type of chlorinated hydrocarbon pesticides, polychlorinated biphenyls and other currently used pesticides.
  We analysed three product categories: bakery products, canned mushroom and meat products. The analysis of the bakery products and of the canned mushroom did not conclude in positive findings, which means that these products contained the agents given during the production of the product and the environmental pollutants in undetectable low concentration.
  However, the results for meat and fish products indicate that polychlorinated compounds are persistent and are of a lipophyl character, as some of these components have been detected in these food products, the concentration of the PCBs were detected in the range of 9.8-24 μg/kg.

  Headspace sampling was studied for GC-MS measurements. A quick, direct method was developed for the measurement of petrol, gasoline and volatile organic solvent contamination of soil. According to our results this method is suitable for quick qualitative analysis of VOC contamination of soil, and helps to make decisions about further measurements. We concluded that an accurate quantitative measurement is not possible.
