The quantitative analysis of selected toxic heavy metals (Cd and Pb) and metalloid (As) as well as the trace element (Zn) in few vegetables and soil has been carried out by specific method-inductively coupled plasma-optical emission spectroscopy (ICP-OES) in our recent research work. Samples of soil and some vegetables were taken close to our four cities/regions in Macedonia: Skopje, Veles, Ohrid and Kocani, in the time period/duration of November to December 2012. We have illustrated the concentration of Cd, Pb, As and Zn for our samples and found in such orders, the highest concentrations of Pb in cauliflower is 1.222 mg/kg, Cd in carrot is 0.192 mg/kg, Zn in leek is 0.319 mg/kg and As in onion is 0.228 mg/kg in the Veles (Bashino village/region), and the highest concentration values of Pb in leek is 1.261 mg/kg, Cd in carrot is 1.027 mg/kg, Zn in carrot 0.251 mg/kg and As in cabbage is 0.057 mg/kg in the region of Skopje (near cement Usje), respectively. All these concentrations are in relation to the prescribed criteria of WHO-World health organization and FAO-Food and Agriculture Organization. Finally, we get that, there is a strong correlation between the concentration of Zn in vegetables and soil in our present analytical work.
