Unknown toxins found by scientists in the waters of Avacha Bay in Kamchatka

Unknown toxins found by scientists in the waters of Avacha Bay in Kamchatka

Scientists at the FEFU Institute of the World Ocean have discovered more than a dozen unknown toxins in the waters of the Avacha Bay in Kamchatka. They could have caused the death of aquatic organisms during the "red tides" in the fall of last year.

As IAA EastRussia was informed in the press service of the government of the Kamchatka Territory, these toxins are the waste products of microalgae. For more than a year, scientists have studied water samples and samples of marine organisms that died in large numbers on the coast of Kamchatka.

Kirill Vinnikov, director of the World Ocean Institute, noted that the study of toxins continues.

“Not all biotoxins are hazardous to human and animal health. Some toxins can be potentially harmful to marine ecosystems. But, since they are still insufficiently studied, we cannot reliably predict exactly what harm they can cause to marine organisms, ”he added.

This year, there was no mass death of animals on the coast of Kamchatka, the ecosystem is being restored.

In the fall of last year, experts discovered that in the south of Avacha Bay, at a depth of 10 to 15 meters, there is a massive death of benthic organisms - 95% are dead. Small numbers of large fish, shrimps and crabs have survived. Experts considered several versions pollution of ocean water in Kamchatka, including technogenic and natural influences. Scientists named red tides- bloom of toxic algae.

Greenpeace team recorded water pollution as several spots of unknown origin... Kamchatka scientists stated that the scale of the disaster will only get worse - the food base of animals that feed on benthos has been destroyed. 

Investigative Committee of Russia opened a criminal case on the fact of pollution of the water area of ​​Avacha Bay and the death of marine animals.
