The Caspian Sea is at risk of becoming a swamp due to pollution
Ecologist Vadim Rukavitsyn warned about the critical condition of the reservoir due to Volga runoff
Quick Look
- The Caspian Sea is at risk of eutrophication due to polluted runoff from the Volga River.
- According to ecologist Vadim Rukavitsyn, pesticides, heavy metals and petroleum products were found in the water, which leads to a decrease in biodiversity and loss of recreational potential.

Why It Matters
The Caspian Sea receives a significant amount of wastewater from the Volga River, which affects the chemical composition of the water. Eutrophication is the process of saturating a reservoir with nutrients, leading to its waterlogging.
The Caspian Sea risks turning into a swamp due to pollution that enters it from the Volga. Associate Professor of the Department of Ecology and Environmental Management of the Russian State Geological Prospecting University named after A. Sergo Ordzhonikidze Vadim Rukavitsyn, writes Gazeta.Ru.
“In general, water in the Caspian Sea in 2024 can be assessed as polluted according to a comprehensive pollution indicator,” the specialist said. Among the pollution are waste products that come from rivers flowing into the sea, mainly the Volga.
In addition, traces of pesticides, heavy metals and petroleum products are found in the water. “If we talk about the impact on the ecosystem, such pollution can consistently lead to eutrophication of part of the sea (turning into a swamp), as well as a gradual decrease in biodiversity. As a result, the sea will lose its recreational value, and all ecosystems adjacent to the sea may also suffer,” Rukavitsyn concluded.
