研究了松花江吉林市至三岔河口江段水体总汞与甲基汞污染特征。结果表明，随着主要工业汞与甲基汞污染源的治理和根治，该江段江水、表层沉积物和鱼类的总汞与甲基汞污染水平逐年下降，目前已基本降到轻度污染水平，而且各江段之间和年际间的差异已不显著，说明该汞源对江段水体的影响越来越小，目前对该江段（鱼和水）汞污染影响较大的是沉积汞。
The pollution characteristics of total mercury and methylmercury in the Songhua River from Jilin City to San Chahe Estuary were studied. The results showed that with the treatment and cure of major industrial mercury and methylmercury pollution sources, the total mercury and methylmercury pollution levels of river water, surface sediments and fish in this section have been declining year by year, and have now basically dropped to mild pollution levels , And the difference between the river sections and the interannual period has been insignificant, which indicates that the mercury source has less and less influence on the water bodies in the section of the river. At present, the mercury pollution to the section (fish and water) HG.
