Authorities and rescue service of Habarovsky krai have taken all necessary measures to reduce risk of ecological catastrophe on Amur, declared the head of Emergency Ministry Sergey Shoigu. "All artesian wells are checked and prepared for water supply, necessary amounts of activated coal for water refinement from benzene compounds are stored, all services have clear plans of actions in case of possible emergency situation", - said minister at session of regional committee over emergency situations in Habarovsk. He noted that water supply turning off is an extreme measure. Russian head of Emergency Ministry confirmed that benzene spot from Sungari river reached Amur. It is expected that pollution zone will be near Nizhne-Leninskoe village of Jewish autonomous oblast. "We made water tests. But there is no exact information about concentration of harmful substances in Amur waters. It will be known in the second part of the day", - said Shoigu. Minister informed that in order to struggle with chemical pollution China sharply increased evacuation of water from storage ponds. In this connection water inflow to Sungari river increased by 3 times, which leads to reduction of nitrobenzene concentration and speed enhancing of pollution zone movement. Due to evacuation of water level of Amur near Habarovsk rose by 1 meter. To prevent consequences of Amur pollution special monitoring group has been formed. "Group, participating in preventive actions, consists of 1000 people and more than 200 units of equipment, including 318 people and 59 units of equipment from side of Russian Emergency Ministry", - noted the minister. At present moment experts of Emergency Ministry are aware of ecological situation in spring. Sufficient part of benzene and of other toxic compounds was absorbed by ice on Sungari and Amur rivers. Catastrophe at chemical plant in Chinese town Czilin took place on November 13. About 100 tons of chemical compounds got into Sungari river, inflowing to Amur.
