Abstract: A field experiment was conducted to study the effects of Pb, Cd, Cu, Zn and As coexisting in red soilon growth of rice （Oryza sativa L.）, mung bean （Vigna rabiata （Linn.） Wilczek）, alfalfa （Medicago sativaL.）, slash pine （Pinus elliottii Engelm.） and aspen （Populus L.）. Results showed that rice, mung bean andalfalfa were significantly innuenced by combined pollution of the heavy metals. The contents of Pb, cd andAs in rice grains greatly exceeded the National Standards for Food Hygiene of China. Heavy metals at ahigh concentration seriously retarded growth of mung bean and alfalfa, but not so obviously with slash pineand aspen. The composite index is suggested for evaluating the relativity of combined pollution witll heavymetals in soil.
