Abstract

Reduction the concentrations of arsenic labile fractions is very important because these fractions are directly related to its bioavailability. This study was carried out to assess the effects of maleic anhydride-styrene-acrylic acid copolymer on the motility and availability of arsenic and corn growth in contaminated soils. For this purpose a factorial experiment was conducted using a completely randomized design and three replications. The examined factors were the rates of application of acrylic acid copolymer (0, 0. 05, 0. 1 and 0. 2%) and the levels of soil arsenic (0, 6, 12, 24, 48, and 96 mg/kg). Corn plant was used as a biological indicator for arsenic phytoavailability and before sowing, the concentrations of soil available arsenic were measured for all soil samples. After harvesting, the Dry weights of aerial parts and roots and concentrations of arsenic and phosphorus of these parts were measured. The results showed that the concentrations of soil available arsenic and root and aerial parts arsenic increased as the concentration of soil total arsenic increased. Contamination of soil by arsenic increased the concentrations of phosphorus in root and decreased it in aerial parts. At all levels of soil arsenic, the application of acrylic copolymer significantly decreased the concentrations of arsenic in soil and in root and aerial parts of corn. The application of acrylic copolymer increased the dry weight of root by decreasing the accumulation of arsenic and phosphorus in plant root. It also increased the Dry weights of aerial parts as a result of increased concentrations of phosphorus and reduced accumulation of arsenic. It is recommended that this acrylic copolymer to be used in reducing the mobility of arsenic in contaminated soils.
