| Research Abstract |
In order to predict the change of heavy metal behaviors with soil acidification, we determined heavy metal fluxes in precipitation, soil water, and stream water in two forest watershed. The heavy metals behaviors were different at two sites. At Tsukuba, the concentrations of metals (Zn, Cd) were significantly higher than those at Katsura. However, surface water acidification and high losses of metals from forest ecosystems have not been detected yet.
