Blatina grapes is fruit crop characteristic of the Herzegovina region. The amount of grapes produced for consumption and processing, greatly exceeding the Herzegovina population needs, and produced fruit has an impact on the quality of the diet to a wider geographical area. The aim of this work is to determine the content of zinc (Zn), as microelement, as well as potentially toxic metal in soil samples and grapes blatina produced in the Mostar region, that consumption in raw form or in form of products, zinc may be involved in human metabolism. Soil samples were taken from a depth of 30cm and 60cm in locations with different modes of production (extensive, intensive - plantation farming and plantation near anthropogenic sources of pollution). From the same locations is taken representative samples of grapes. In soil samples and grapes samples were determined physicochemical properties and the content of zinc. Zinc content was determined by atomic absorption spectrophotometry, flame technique (FAAS). Zinc content in the grapes blatina is in range of 0,677 to 0,840 mg/kg and is not noticed relation with zinc content in the soil, but it is observed relations between blatina fruin zinc content, cultivation methods and the presence of anthropogenic pollution sources.
