摘要: 表本文按水文地理特征采集松花江流域未受污染的水样95个,悬浮物样53个、鱼样100个、沉积物样144个.其汞的分布类型大多呈正态和对数正态分布。流域水体中汞的背景值分别为水-0.009-0.025ppb、悬浮物-0.651-2.757ppm、鱼-0.050-0.254ppm、淤泥级沉积质-0.016-0.070ppm和沙质沉积物0.008-0.023ppm.

Abstract: The Songhua River is an important economic river in the Northeast China From the Songhua River basin,95 unpolluted water samples,53 suspended substance samples,100 fish samples and 144 sediment samples are collected.The test of the distribution types of the mercury in the water body show that the mercury in water,suspended substances,fish,and sediments presents mostly normal and logarithmic normal distributions.The background values of the mercury in the water body of the basin are 0.009-0.025ppb in water,0.651-2.757ppm in suspended substances.0.050-0.254ppm in fish,0.016-0.070ppm in silt sediments,and 0.08-0,023ppm in sandy sediments,respectively,
