Bio-indication in the Amur River, Russian Far East

The technogenic accidents in Jilin province (China) in November 2005 and July 2010 have drawn attention to environmental problems of the Amur River basin. The lack of reliable information on the anthropogenic pressure of natural complexes in newly developing northern territories of China, namely, the Sungari Basin and the right bank areas of the Amur River, makes the efforts of the Russian authorities less efficient in conserving Amur ecosystem biodiversity and in reducing river water pollution. Studies of algal biodiversity and structural dynamics of the Amur River ecosystem reveals the impact of phenols on water quality which was followed till the river mouth. Bio-indication and statistics help us to reveal species-indicators and bio-sensors of pollutants. These algae are more influenced by phenols in low-mineralized unpolluted water. The ecosystem on the oligotrophic level is more impacted by the chemical pollutants and degrades from left riverside to right across the river especially after impact of the Sungari River input.
