Abstract

Twenty two soil samples with various chemical and physical properties were collected from different sites of Khuzestan province and chemical forms of soil cadmium (Cd) were determined using a SEQUENTIAL EXTRACTION technique. A greenhouse study was conducted to evaluate the relationships between the chemical forms of cadmium and its availability for WHEAT plant. The results showed a positive correlation between soil DTPA-extractable Cd and electrical conductivity (EC) in the studied soils (r=0.65, p<0.01). The soluble+exchangeable form was lowest (5.1%) and the carbonate fraction was the highest (40%) cadmium fraction in these soils. Soluble+exchangeable fraction was positively correlated with soil DTPA-extractable Cd and electrical conductivity. Carbonate fraction showed a significant correlation between clay and active carbonate calcium content in the studied soils. The results also showed that cadmium concentration in WHEAT grain was not correlated with any soil physico-chemical properties as well as soil Cd fractions. Although comparing the results for soil total Cd with those reported as contamination threshold revealed that more than fifty percent of the studied soils were Cd contaminated, only 3.1% of the grain samples exceeded maximum permissible Cd concentration suggesting total Cd concentration is not an appropriate index for Cd uptake from soil.
