Abstract
In this study, soils and plants of ultramafic areas of Neyriz, in the south of Iran, were collected, identified, and analyzed for “serpentine” metals. Soil analysis of total element concentrations indicated that maximum total concentrations (µg g-1) of Ni = 1250, Cr = 200, Co = 295, Mn = 1850, Fe = 105,300, Mg = 73,000, and Ca = 2800. The maximum concentration of exchangeable Ni in these soils was of 4.7 µg g-1. During this study, 116 plant species belonging to 30 families were collected and a few species were endemic to ultramafic soils of these areas. Analysis of the plant leaves did not reveal any hyperaccumulators of Ni or any other “serpentine” metals. The highest concentrations of Ni (140 µg g-1) and Co (47 µg g-1) were found in Rheum ribes. The highest concentration of Cr (76 µg g-1) was measured in Nepeta glomerulosa.
