The Songhua River (SHR) is one of the seven major rivers in China. It feeds into Heilongjiang River, which is the natural border river between China and Russia. The water quality and security of the border river plays an important role in relations of two countries and the economic development for border region. This article collects the papers about researches on organic pollutant in SHR of recent 40 years. With the research study result, this article analyses organic pollutant change trend in terms of detected category, amount and distribution. It shows that the organic pollution is severe and caused negative impact on ecological environment because of industrial development near river bank during 1970–2000. The water quality of SHR has been improved and changed to slight pollution due to the implementation of basin pollution prevention planning in 21st century. The pollutant categories have decreased with lower concentration trend. This study suggests the research orientation for organic pollution of SHR in the future.
