Abstract
- In order to probe to the factors for mercury accumulation to natural surface coating, we study the concentration of mercury in Huangpu River surface coatings developed for different depth, different grown days and different seasons and analysis mercury forms of occurrence. The result show the organic matter in biofilm is much high (7.5%-14.5%). Growth time, depth and seasons are all important factors for mercury accumulation to surface coating. Illumination and temperature was stronger and the growth day was longer, The concentration of mercury in biofilm was higher. The mercury forms of occurrence in surface coating were mainly residual matter bound mercury (41.98%) and organic acids bound mercury (27.89%). The percentage of carbonate bound mercury (10.17%) and ion exchangeable mercury (5.33%) was little.
