Guilty The researcher explains why blooming blue-green algae in the Baltic Sea is expanding more and more – Green Life

Boikova explains that in the Baltic Sea, during periods of severe weather, the formation of blue-green algae was observed a few centuries ago. This is a very old phenomenon in the Baltic Sea, but because of human activity resulting from anthropogenic loads and agricultural wastewater, this phenomenon is becoming more and more prevalent, causing serious damage to the sea. 39, Ecosystem

. when there was no intensive industry, there was a proliferation of blueberries in the Baltic Sea.The question is how much and how long, "said the researcher.

In the spring, when enough d & rsquo; Nitrogen and phosphorus are introduced into the river, blooming from other algae, which does not use these substances.In the summer, when the inorganic nitrogen is close to zero, biombades of 39 blue-green algae able to eliminate the nitrogen necessary for their life in the air are destroyed, explained Boikov

.Blood in the upper layers. for other organisms are not a precious food, and they do more harm than good – in huge layers, they start to break down slowly, settle on the seabed and consume from the sea. As a result, oxygen-free zones are formed – previously, they were in the most deep in the Baltic Sea, for example in the mouth of Gotland. But now, Finnish scientists are worried that the non-oxygenated areas have been expanding rapidly for the past decade, one of the reasons being the rapid rise of blue-green algae, said Boikova

but without the blue-collar workers of the Baltic Sea. said the researcher, adding that contamination is also promoted by pharmacology, cosmetology.

"The load on the sea is very important, it has an impact on the organisms.It explained that the sea, like humans, has adaptability – the sea is able to perform some self-cleaning process, but "how far the red line will come," said Boikova, after which everything can go completely tangentially, we can not say it for the moment. "[19659002] Boikoff also stated that for each region of the Baltic Sea, this "red line" is individual and unique. As the diversity of species in the sea is not high, its ecosystem is very fragile because each species performs a certain function. Therefore, the less body there is, the easier it is for the ecosystem to eliminate the balance. While the Baltic Sea is one of the most-explored seas in the world's oceans, many questions remain unanswered, says Boikova.

Now, with a sharp increase in blueberries, nothing can really be done. She told me that Swedish colleagues had been trying to pump oxygen into the sea to speed up the blasting process of the blue-green algae, but that was not really the case until the ## 147 ## 39, now.
