Be careful – if one day you decide to swim in the fresh water in the summer heat, you may suddenly feel uncomfortable. It can cause skin irritation, fever and even liver disease, since in warm weather the so-called blue-green algae bloom in the water. They release toxic substances into the water that harm not only humans but also pets. Recently, four dogs died in the US from the effects of these plants. In some cases, it took several hours between bathing in contaminated water and death.
In the US states of North Carolina and Georgia, cases of animal deaths were recorded by blue-green plants. Owners of domestic dogs told how their pets bathed in fresh water and began to behave strangely after a few hours. In particular, it was a severe debilitation and severe vomiting, indicating that the owners brought the pets to the veterinary clinic. On the way, the dogs fainted and then died.
Why are algae dangerous?
While doctors can not name the exact cause of death, blue-green algae are regarded as offenders in advance. In fact, they are not really plants, they are microscopic beings called cyanobacteria. They are called algae because, like plants, they can absorb the sun's rays and convert them into life energy. During the summer heat, these bacteria become very numerous, so this period is sometimes referred to as the bloom of blue-green algae.
Reckless Animal Killer – Cyanobacteria
To a lesser extent, they can not harm people – lovers of a bath in the lake sometimes do not even notice them because of their small size. However, during flowering they begin to form clusters, and on the surface of the water one sees dark green lumps and "threads". In most cases, the water becomes frothy and turns brown, yellow or green. In such lakes, it is better not to climb.
Blue-green algae even kill fish
The biggest damage is caused by cyanobacteria when they invade a person when they inadvertently swallow water while swimming. In these cases, people may experience nausea, mouth blisters, and serious liver problems. According to statistics, the United States recorded about 11 outbreaks of algae-related diseases between 2009 and 2010. During these epidemics, at least 60 people were affected. In general, poisoning with blue-green algae was first mentioned in 1000-year records in China.
Not all algae are harmful. Some of them save astronauts from starvation
How not to poison with algae?
In order to avoid being poisoned by algae, it is important to check every time that the water in the pond is really clean. We have already mentioned that it is better not to get into the frothy waters of brown, yellow and green. If it still stinks, it is better for safety reasons not to approach the water at all. Also watch out for the drinking water and make sure it has been thoroughly cleaned.
Do you see such water? Run away from her soon!
Scientists believe that blue-green algae will become more dangerous over time and the number of diseases will increase dramatically. The fact is that the temperature of our planet is constantly rising – the summer of 2019 is considered one of the hottest in history. Under warm conditions, bacteria multiply rapidly under the influence of the scorching sun. Maybe their clusters are already found in lakes that you always thought were clean.
