Determination of trace elements in cole (Brassica oleraceae var. acephale) at Trabzon region in Turkey

The elemental analysis of cole (Brassica oleraceae var. acephale) has been carried out in the Trabzon region (Turkey) using energy-dispersive X-ray fluorescence (EDXRF) spectrometry. Cole is one of the most commonly consumed vegetables by people living in that region. The reason for this is its abundance and easy growth in four seasons. We have analyzed cole samples for 11 stations using 50 mCi Fe-55 and Am-241 radioactive sources. We have found that potassium was present in the highest concentration in cole for every station. The concentration of Cl generally changed according to the distance between the sea and the sampling station.
