Abstract
Concentrations of trace and major metals in dry fallout, bulk precipitation, and rice roots were determined in the Takahashi River basin on whose estuary stands the Mizushima industrial area, one of the largest in Japan. The data were analyzed by principal components factor analysis.
The amounts of volatile metals Zn, Cd, Pb, Cu, Ni, V, Cr, Be, Sn, and Ag were delivered from the atmosphere as dry fallout and precipitation, especially within the industrial and highly populated areas. Concentrations of trace metals such as Zn, Cd, Pb, Cu, V, Ni, Cr, and Be in rice roots were 2–4 times higher in the industrial, urban, and roadside areas when compared with those in sparsely populated areas.
