Be careful — if you one day decide to swim in the freshwater lake in the heat of summer, you may suddenly feel bad. You may have irritation of the skin temperature to rise, and because warm weather in the so-called water bloom blue-green algae. They emit in the water of toxic substances that harm not only people but also Pets. Recently, through the fault of these plants killed four dogs, and very quickly — in some cases, between bathing in contaminated water and death, passed a maximum of a few hours.
The deaths of animals from blue-green plants have been recorded in the U.S. state of North Carolina and Georgia. The owners pet dog told of how their Pets swim in fresh water and after a few hours began to behave strangely. In particular, they talked about the strong weakening and vomiting, noting that the owners took the Pets to the veterinary clinic. Along the way the dog lost consciousness and then died.
While doctors can not give an exact cause of death, but the perpetrators are known to be blue-green algae. In fact, they are not quite are plant — rather, microscopic creatures called cyanobacteria. They are called algae because of the fact that they, like plants, can absorb the sun's rays and transform them into vital energy. During periods of summer heat these bacteria becomes very much, so this period is sometimes called the blooms of blue-green algae.
Ruthless killers of animals — cyanobacteria
In small quantities they can harm people — because of their tiny size, lovers to swim in the lake sometimes don't even notice them. However, during periods of flowering, they begin to form clusters, and on the surface of the water you notice dark green clumps and "strings". In most cases the water becomes frothy and turns a brown, yellow or green. In such lakes, of course, better not to go.
Blue-green algae even kill fish
The more damage cyanobacteria cause ingestion of man, when bathing he accidentally swallows water. In these cases, people may experience nausea, blisters in the mouth and serious liver problems. According to statistics, from 2009 to 2010 in USA there were about 11 of outbreaks of diseases associated with algae. During these outbreaks affected at least 60 people. Generally, the first time poisoning blue-green algae mentioned in the 1000-year old records, found in China.
Not all algae is harmful. Some of them
To avoid algae, it is important to check that the water in the reservoir is really clean. We have already mentioned that in the foamy water brown, yellow and green better simply not to go. If the water is still and there is a stench, for greater security it is better not to approach. It is also worth to pay attention to drinking water and to make sure she was thoroughly clean.
See this water? Run away from her more!
Scientists believe that over time, the blue-green algae will become even more dangerous and the number of diseases will increase dramatically. The fact that the temperature of our planet is constantly increasing — summer 2019 is considered . In warm conditions, under the influence of the scorching sun, bacteria multiply with great speed. Perhaps these clusters can already be found in the lakes that you have always considered clean.
