Ecologists study this year showed that for the first time for the last 6 years, the fish in the Amur River fully meet sanitary standards, according to a government website Friday Khabarovsk Territory.
Increased attention to the ecological status of the river has been given after the accident at a chemical plant in the Chinese city of Jilin November 13, 2005, because of which the Songhua River (a tributary of the Amur) has got more than 100 tons of benzene compounds, which are then turned into the Amur.
Then the scientists also said the systematic pollution of the Amur, which reflects the fish — it was a strong odor of phenol, it contained toxic chemicals — phthalates, naphthalene, and pesticides. In recent years, environmentalists point improvement in the river.
The latter study was derived from the analysis of 48 species of fish caught in the villages Golovin, Volochayevka (Jewish AO), Khabarovsk, Komsomolsk and Nikolaevsk-on-Amur.
"The analysis was conducted on more than 20 chemical and microbiological and Helminthological indicators. As a result, only two samples revealed deviations MPC on chemical composition and microbiology. First time in 6 years Amur fish is fully consistent with SanPiN" — said the deputy head of environmental policy and environmental monitoring MEP region Anatoly Frolov.
This fact was confirmed by representatives of the Khabarovsk branch of the Pacific Research Fisheries Centre (TINRO center). Head of Coordination of Environmental Studies Sergei Kulbinsky said that his organization has been monitoring the water and the fish in the pond 21. Selected in this year's fish really showed no exceedance. According to him, it is said that the water in the reservoirs edge improves.
"For the first time this year in the channel Amur The appearance of insects such as the" caddis fly. "This species lives only in clean, running water, such as in mountain rivers. Our water is, of course, is far from ideal — quality class this year promoted from 4-5 to 3-4. But the fact of the appearance of "stonefly" already indicates that the dynamics of the Amur water positive, "- said Kulbitsky.
