A series samples of atmosphere,plant and soil were collected and analyzed of Hg content at different function regions in acid precipitation area. The results showed that the pollution of Hg from atmosphere to soil plant system was very serious.There was a significant possitive correlation between the concentration of atmospheric Hg and its accumulation in soil plant system ( r =0.741 ** , n =52 for the soil and r =0.882 ** , n =53 for the plant).In areas where the concentration of atmosp...
