Serious oil pollution has been recorded in the Yenisei River in Krasnoyarsk Krai following an accident involving a ship belonging to the Ob-Irtysh River Shipping Company. The oil content in the water exceeds the maximum permissible levels by 14-40 times. The incident, which occurred due to a hole in the ship, has alarmed environmentalists, who are warning of a high risk of mass death of flora and fauna. An investigation has been launched into the company that owned the ship, and regional authorities and federal agencies are assessing the scale of the environmental damage.

The incident occurred on a section of the Yenisei River near Krasnoyarsk, where a ship carrying diesel fuel sustained damage to its hull, causing a fuel leak into the river. According to the regional Ministry of Ecology, the first water samples taken in the accident zone showed a critical excess of petroleum products. Such indicators pose a serious threat to the ecosystem of the Yenisei, one of Russia's largest rivers, which provides water to millions of people and is home to many species of fish, including valuable species such as sturgeon and taimen. Environmentalists fear that the spill could lead to long-term consequences, including disruption of food chains and the destruction of aquatic biocenoses.
