A message about the release of yellow substance along Motornaya Street in Naberezhnye Chelny was received by the Prikamskiy Territorial Administration of the Ministry of Ecology and Natural Resources of the Republic of Tatarstan through a single emergency dispatch service of the Ministry of Emergencies. As ecologists found, a yellowish coating on the snow cover arose due to the ingress of a chemical substance - hexavalent chromium - into the air. The area of pollution was 12,566 square meters.
