Özet
In this study, the different fractions of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn in the soil samples have been determined by means of BCR sequential extraction method which was developed by the European Bureau of Reference. The amounts of heavy metals which are taken by plants have been determined through DTPA (diethylene triamine pentaacetic acid) extraction method and the relationship between sequential extraction method and amounts of heavy metal taken by plants have been statistically analyzed. Flame atomic absorption spectrometry (FAAS) has been employed to find out heavy metals extracted through BCR sequential extraction and DTPA method. In this study, it has been statistically found out that there is a strong relationship between heavy metals (Cd, Cr, Cu, Fe, Mn, Pb and Zn) except for Ni and Co which can be extracted through DTPA and F1 fraction (exchangeable and carbonate-bound). It has also been seen that this relationship can provide significant information while interpreting heavy metal behaviors and available amounts. Besides, it has been observed that there is a statistical relationship between metal amount bound in F2 (Fe-Mn oxides bound) and F3 (organic matter and sulphure bound) fractions and metal amounts extractable through DTPA. It has also been seen that these relationships can provide information for heavy metals about their bioavailability in the long term.
