Nitrobenzene levels in the area of the slick that has come from China’s Sunguri River to the Amur and is passing Komsomolsk-on- Amur are hundreds of fractions of a maximal permissible concentration, a spokesman at the regional Emergency Situations Ministry told Itar-Tass on Thursday. The water at all river scoops is treated with activated coal, and the city’s population has no problems with the drinking water supply. The water in city systems meets all sanitary and hygienic standards. However, caught fish confirms apprehensions of hydrologists and ichthyologists. Fish monitoring by specialists of Khabarovsks’s research centre showed that fish has a sharp odour of chlorine and other chemicals and is unusable as food. One maximal permissible concentration of chemicals for humans is 20 times the figure for fish, experts say. Fishing has been banned in the Khabarovsk region and the Jewish Autonomous Area. Nanais, Ulchis and other aboriginal minorities living near the Amur are having problems, as fish is their main food.
