Abstract
Water quality of Lake Baihua was found worsening in the autumn of 1994. Studies have shown that the decomposition of organic matter in the upper-level sediments resulted in seasonal anoxia with the release of P, Mn, and S2− from the sediments to the overlying water column, and the increase of NO −2 concentration led to blackening of the water column, death of fishes and secondary Mn pollution.
