A series of explosions at China's Jilin Petroleum and Chemical Company November 13 polluted the Sungari River, the right tributary of the Amur River, which forms a natural border between Russia and China.
The polluted water may soon reach the Jewish Autonomous Area and the Khabarovsk
Territory in Russia's Far East.
"We will take all measures to prevent any health problems in the Khabarovsk Territory," Natural Resources Minister Yury Trutnev said.
He said the ministry needed more information from China on the chemicals in order to take effective measures against the pollution and that the Russian Emergency Situations Ministry was also involved.
According to the latter, about 1,500 people use the Amur water in the Jewish Autonomous Area and 1.5 million in the Khabarovsk Territory.
All water testing facilities in the area have been put on red alert.
