Pollution
The water pollution is relative low and mostly originates from the numerous plants and mines standing on the Lena, Yana and Anabar rivers. Their waste is contaminated with phenols (0.002–0.007 mg/L), copper (0.001–0.012 mg/L) and zinc (0.01–0.03 mg/L) and is continuously washed down the rivers into the sea. Another regular polluter is the coastal Urban-type settlement of Tiksi. Occasional petrol spills occurred due to navigation and petrol mining. Another major contaminant is associated with floating and sunken wood in the sea, due to decades of rafting activities. As a result, the phenol concentration in the Laptev Sea is the highest over the Arctic waters.

Famous quotes containing the word pollution:
“Like the effects of industrial pollution ... the AIDS crisis is evidence of a world in which nothing important is regional, local, limited; in which everything that can circulate does, and every problem is, or is destined to become, worldwide.”
—Susan Sontag (b. 1933)
