摘要: Bottom mud was collected from the upper and lower streams of 91 rivers in Japan to determine distribution Al, Fe, Mn extracted HNO3-H2O2 0.5 N HCl. The concentrations by ranged 2, 900 67, 000 mg·kg-1, 1, 500 57, 300 23 861 mg·kg-1 dry mud, respectively. About 95% all samples contained HCl soluble Al less than 5, their corresponded about 10% Al. No difference between could be observed. 90% stream 35% Fe mg·kg-1. A increased stream. concentration almost rivers, average decreased slightly variation coefficients these three metals were smaller those trace metals.
