Abstract

Water and soil samples were collected from Homanzan mine fields and its neighborhood , and cadmium and copper contents in the samples were measured with an atomic absorption spectrophotometer to clarify the distributions of heavy metals in the area. The contents of the heavy metals in the water collected along the stream taking its rise among the abandoned mine fields decreased with distance from the riverhead. However, considerable amounts of the heavy metales were detected even from the bed soil of the river-mouth flowing into Lake Nakaumi. No correlation was found between the number of the fungi isolated from the samples and the heavy metales contents in the samples.
