Contamination of soil at depths more than 30-40 cm has not been registered
MOSCOW, December 28. /TASS/. Scientists studied petroleum products’ concentrations in soil in Norilsk, where fuel spilled from a tank at a power plant, and said they did not find ecology hazardous contamination levels there, the Great Norilsk Expedition said in its final report.
The expedition was organized by the Russian Academy of Sciences’ Siberian Branch.
“The evaluation and analysis of petroleum products’ concentrations in surveyed soils of examined watersheds has not pointed to their high, ecologically hazardous levels even in the soil not far from the accident’s area,” the report reads. “Often, maximum high concentrations of petroleum products were seen not on the surface, but inside the lower layer of soil. Contamination of soil at depths more than 30-40 cm has not been registered.”
