Abstract: This paper dealt with the effects of 2+,2+ and their combined pollution on the contents of chlorophyll,potassium and calcium in Thuidium cymbifolium.The results showed that except at 0.1 mg 2+-1,the chlorophyll content decreased with increasing 2+ and 2+ concentrations,which was 18% of the control at 100 mg 2+-1,and decreased by 48.6% at 200 mg 2+-1.The potassium and calcium contents also decreased with increasing pollutants concentrations,being decreased by 61.1% at 100 mg 2+-1.2+ had a stronger toxicity than 2+,and the toxicity of their combined pollution was stronger than that of each pollutant.2+ could increase the toxicity of 2+.

Key words: Lead, Cadmium, Thuidium cymbifolium, Physiological characteristics
