Plants of the potato cultivar Desiree used for this study have been collected from the following sites in Serbia: Ivanjica (soil type: gray brown skeletoidal soil and flysche), Mrcajevci (alluvial smonitza-meadow slois), Borca (chernozem), Guca (parapodzol pseudogley), Leskovac (marsh black soil), Belegis (chernozem), Rajac - Gornji Milanovac (shallow back soil buavica on limestone), PKB-Beograd (chernozem), Smederevo (alluvium), Dobanovci (degraded chernozem in the process of browning), Pozarevac (smonitza), and Novi Pazar (ranker). The analysed potatoes of cv. Desiree, grown on various sites in Serbia, have starch content that corresponds to available literatura date. On the basis of heavy metal contents in potato samples, it may be concluded that potatoes originating from sites famous for potato production are contaminated with Cd the content of which exceeds concentrations permitted by regulations. The presence of Cd in potato samples may also be explained by application of phosphate fertilizers in higher (or recommended) rates. However, the soil itself should also be investigated, especially concerning the content of Cd and pH value. Thus, the influence of the soil itself should be established compared to fertilizer application in the current season. Presence of Cd in potatoes, on the other hand, is highly unfavourable because it prevents its utilization in nutrition, but also as a raw material for further processing of products based on potatoes: chips, etc. Analyses of lindane and bensultap (Bancol) pesticides indicate that they are not within critical values, nor in such quantities to affect human health, so, from this aspect, the analysed potato samples from all sites are absolutely suitable for consumption.
