title: [Application of ICP-MS to detection of heavy metals in soil from different cropping systems].
abstract: With the rapid development of the society, more and more attention has been paid to the influence of human activity on environment and food pollution. Soils of different cropping systems, sampled from Daxing district of Beijing, were analyzed in terms of the contents of heavy metals (Ti, Cr, Mn, Ni, Cu, Zn, As, Cd and Pb) by the method of ICP-MS to determine the influence of cropping system on environment. The results showed that the contents of nine heavy metals in soils from the cropping systems (fruits and maize/wheat) were several times higher than those from vegetable system. Contents of Cr, Mn, Ni, Cu, Zn, As and Cd were the highest in soils from fruit system, while Ti and Pb the highest in soils from maize/wheat system. The causes of the above differences could be the different harvest organs for different crops.
