摘要：Samples of Solanum tuberosum L. and soils were collected in 2013 from roadside, centrical, rural, secondary roads and control area of five locations Derinkuyu, Kaymakli, Qardak, Mazi, Zile in Nev§ehir. In this study, Cd, Cr, Cu, Ni, Pb and Zn accumulation in the collected soil samples was determined by ICP- OES equipment. The lowest and the highest levels of Cd (0.01-1.08 ^gg_1 dw), Cr (1.16-62.68 (igg-1 dw), Cu (1.1-38.79 (igg-1 dw), Ni (1.29-63.41 (igg-1 dw), Pb (0.52-13.86 (igg-1 dw) and Zn (2.87-69.81 ^gg'1 dw) in the soils have been determined. Levels of heavy metals in the soils were below the limits of the Turkey soil pollution control regulations standard (TSP, 24609). The accumulated heavy metals were quantified and their levels compared to the FAO/WHO Codex-Stan 179:2003 contamination limits. The lowest and the highest levels of Cd (0.01-1.90 (igg-1 dw), Cr (0.08-0.98 (igg-1 dw), Cu (0.52-18.57 (igg-1 dw), Ni (0.02-5.35 (igg-1 dw), Pb (0.02-1.08 igg-1 dw) and Zn (1.08-43.84 igg-1 dw) in the potatoes have been determined. Ni was only found in the potatoes from 3 sites (Kaymakli and Derinkuyu centre) and the level is above the FAO/WHO’s limit levels. As a result, Pb, Cd, Cr, Cu and Zn concentrations in the potatoes samples taken from Kaymakli and Derinkuyu were also found above the limits.
