[Effects of soil use along Yellow River basin on the pollution of soil by heavy metals].
Because of the decrease in pasture and woodland proportion, soil loss is severe along the Yellow River basin. The Yellow River delta has been one of the deltas that form land most quickly. Research on the pollution of new land is important for its use and appraising the environment and food pollution along Yellow River basin. The contents of heavy metals (Mn, Cu, Zn, As, Cd, Pb, Hg and Cr) in new soils (2006) and old soils (1996) from Yellow River delta, were analyzed by the method of ICP-MS/ICP-AES, in order to determine the level of pollution along Yellow River basin. The results showed that the heavy metals pollution along Yellow River basin is increasingly severe, especially the concentrations of Mn, Cu, Zn, Cr and Cd in soil forming in 2006 are significantly higher than those in 1996, which should be noticed by our government.
