Abstract
Plant uptake is one of the major pathways by which toxic metals enter to human food chain. The irrigation water, important source of toxic metals in plants, is contaminated with effluent and other pollutants due to the widespread industrialization. Cadmium has an increasing international concern because its toxicity is generally considered to be much higher than those of other heavy metals and it is readily taken up by plants.In this study, cotton plants were grown by using the Cd-added irrigation water at different concentrations. The Cd applications in the irrigation water caused a decrease at dry weight of root samples in the first two weeks compared to control, but an increase observed by increasing Cd dose. Cd and Fe concentrations in seedlings increase dependent on increasing Cd levels in the irrigation water except highest dose of 0.1 mg l -1 . The other elements analyzed including Zn and Cu don't change by increasing Cd levels in the irrigation water.
