YEREVAN. - According to Environmental Impact Monitoring Centre of Armenian Ministry of Nature Protection, the norms of Vanadium, Chrome and Nickel in some cases exceed the permitted norms in the waters of Masrik, Sotk, Argichi and Gavaraget rivers that flow into Lake Sevan.

This is a consequence of asphalt production and emission of gas stations.

However, according to econews, certain data is kept secret from the society. Thus, heavy metals found in Sotk and Masrik rivers basically pollute the river sediment. Moreover, heavy metals found in these rivers are also present in Sotk gold mine adjacent territory meaning that operations in the mine pollute the area, the rivers and consequently Lake Sevan.
