Oil spills are a major threat to the ecology of the Caspian Sea, experts said the two littoral states of Russia and Kazakhstan at the press conference in RIA Novosti, while environmentalists say untreated sewage Azerbaijan the main source of pollution.
"External sources of pollution (untreated sewage — Ed.) Caspian important, and to prevent this risk is necessary, but what is happening with natural resources (marine oil — Ed.) Much more serious. Before our eyes becomes apparent threat of degradation of the unique biodiversity of this ecosystem "- said a senior researcher at the Institute of Oceanology, Russian Academy of Sciences Boris Golubov.
Golubov opinion supported Deputy CEO "ScanEx" that leads the space monitoring of the Caspian Sea, Alex Kucheiko. The expert noted that in 2011, stranded stranded tanker "Gregory Bugrov" with six thousand tons of fuel oil on board could cause an environmental disaster comparable to the oil spill in the Gulf of Mexico. Fortunately, said Kucheiko, oil does not leak from the tanker, and the ship itself was evacuated in time, but the continuous monitoring system in the Caspian Sea is not, and such luck may not be repeated.
Runoff dangerous oil?
The President of the Azerbaijan National Center for Ecological Forecasting Telman Zeynalov said that only 2-3% of the pollution caused by the oil, and the main problem of the Caspian — raw sewage.
According to head of the environmental and conservation policy of the Ministry of Ecology and Natural Resources of Azerbaijan Rasim Sattarzadeh, the country spends about a billion dollars in wastewater treatment. He also noted that any economic activity, in particular the oil industry, a negative impact on the environment, but that is no reason to stop it.
However, as a Russian expert said Boris Golubov, a danger not only to leaks and spills, but also the fact that the active mining provokes natural remedies oil on the sea surface. Anxiety among Russian ecologist also cause flooding and shut-in well, preservation of which has not yet been carried out. A large number of inactive wells, said Golubov, in the territory of Azerbaijan and Kazakhstan.
"We (in Kazakhstan — Ed.) After rising sea level flooded a number of wells, and we can not kill their way. This is a serious danger. Oil film thickness in microns, destroying all life on the depth of three meters. This is much more dangerous than sewage ", — the chairman of the Ecological Union of associations and enterprises of Kazakhstan" Tabigat "Mels Eleusizov.
