Laptev Sea Pollution

Reference work entry

Laptev Sea Pollution – traditionally the sources of pollution are oil carbohydrates, wastewater, water transport, etc. In Bulunkan Gulf, lying in the middle part of the western shore of Tiksi Bay, the oil carbohydrates reach the threshold allowable concentration of 20 and it is considered catastrophic; in Buor-Khaya Gulf they amount to the concentration of 12. High content of oil products is typical for the sea navigation route. Spues of uncleansed flows of the settlement of Tiksi add to the pollution of coastal waters. They are polluted by carbolic acid to a great extent. Its high concentration may be explained by a huge amount of sunken timber. Carbolic acid content in the offshore of the Yana and the Lena reaches the concentration of 5, in the Yana Gulf of 60, in Buor-Khaya Bay of 45, and in Bulunkan of 22. The water in the Neelov Gulf is marked by dirtiness and in the Tiksi and Buor-Khaya bays by pollution.
