Abstract

Abstract: In order to investigate the relationship between the arsenic forms in soil and arsenic accumulation in grains, provide scientific basis for the safe use of the contaminated farmland, reducing arsenic transport to the food chain and the safety production of grain, the author measured the total, available and carbonate-bound arsenic content in soil and analyzed the arsenic content in wheat and maize grain in the corresponding points. The results showed that the arsenic content of different forms in soil varied significantly, which was induced by exogenous pollution. Arsenic content in wheat collected from moderately and severely polluted points exceeded the national standards, the accumulation of arsenic in maize grain was lower than that in wheat. Arsenic accumulation in wheat grains was stronger than that in maize grains. Arsenic content in wheat grain was obviously correlated to the contents of all arsenic forms in soil. However, arsenic value in maize was slightly correlated to different forms of arsenic in soil. The difference was related to the growth cycle and physiological characteristics of wheat and maize.
