Bottom of Lake Baikal Contains Toxins
How dioxins work

Russian geochemists warn that bottom sediments of unique lake Baikal contain dioxins and similar toxins, which indicates that pollution from Baikal pulp-and-paper plant goes on.
      Last summer Mir-2 submersible brought samples of bottom sediments of a used-to-be-the-cleanest-lake-in-the-world Baikal, which were forwarded to a laboratory for tests. Analysis showed that concentration of toxic substances didnt change in lake sediments near Baikal pulp-and-paper plant since 1997.
      Natural environment of the area doesnt contain any dioxins, researchers say, these substances come solely from industrial wastes. Dioxins tend to accumulate in living beings, causing a variety of health disorders.
