Abstract: The content of Cu, Zn, Ni, Pb, Cr, Cd, As and Hg in 8 rock samples, 10 soil profile samples (100cm), 65 soil surface samples and 59 crop samples collected from a glacial-eroded area in Yunnan was determined by acid dissolution and ICP-MS. The results showed that the content of chromium, nickel and copper in basalt in the investigated area was significantly higher than that in limestone, and the metals exceeding the risk screening value of soil in the investigated area were chromium, nickel, copper and cadmium, among which the proportion of chromium was 50%~100%, nickel was 33%~93.1%, copper was 13.64%~93.1%, and cadmium was 3.03%~10.34%. The elements exceeding the risk control value were chromium and arsenic, accounting for 6.9% and 3.03%. Except for the high percentage of cadmium and arsenic in the total amount, the other heavy metals in the total amount of available state content were very low, and the effective state of chromium is lower than the detection limit, which may be due to the insoluble state of chromium in unweathered basalt minerals. The edible parts of arsenic, lead, mercury, cadmium, chromium, zinc, copper and nickel of 59 agricultural products collected did not exceed the corresponding standard limit values.
