| Research Abstract |
In order to consider the effects of humic materials on transport of pesticide in soil and water environment, the adsorption of pesticide by humic materials was examined. By using the DEAE by which adsorbed humic acid or fulvic acid, the adsorption of some pesticides with different Kow by humic acids and fulvic acids were compared. These were no difference of adsorbed capability of DEAE adsorbed capability of DEAE adsorbed fraction on humic acid and on Fulvic acid. Partition coefficient of adsorption and of desorption of each pesticides from humic materials were obtained.
The effect of humic acid on the biodegradation of MEP ware examined too.
