At the bottom of the former Kakhovka reservoir, scientists have discovered the remains of hazardous substances, including heavy metals that can negatively affect the environment. The Guardian reports this, citing a study published in the journal Science.
Despite the fact that this area is now covered with dense greenery, the soil here is not as safe as it might seem. Experts have found out: for decades, dust from industrial enterprises located upstream of the Dnieper River settled on the bottom of the reservoir, accumulating toxins. After the destruction of the Kakhovka hydroelectric power station, this layer of silt began to disperse over the surrounding areas.
Ecologist Oleksandra Shumilova explained that fine dust particles act as a porous “sponge” that absorbs and retains harmful substances. The total volume of these deposits reaches 1.5 cubic kilometers. They are now entering the soil, water, and vegetation, posing risks to local ecosystems. Heavy metals can cause cancer, hormonal disruptions, organ damage, and can also enter the food chain, threatening predators and large animals.
Despite this, according to Professor Ivan Moisienko from Kherson, the risk to humans is currently minimal. There is no permanent population in the area of the former reservoir, and agricultural activity is sporadic. This significantly reduces the likelihood of toxins reaching humans through food or water.
However, there is some positive news: plants, including willows, which actively inhabit the former bottom of the reservoir, act as natural filters. They are able to accumulate and partially neutralize toxins - a process known as phytoremediation. Scientists believe that thanks to this natural mechanism, it is possible to gradually reduce the level of pollution in the area.
