Cyanobacteria and algae
What to when swimming in natural pools attention? Certainly bathe in places that are visibly polluted with sewage, for example, under the effluents from sewage treatment plants and the storm sewers. Water could be germs and intestinal or stomach problems can certainly forgive everyone likes.
The longer it takes to warm weather, the more the water level will turn green and blossom. It's the phytoplankton, specifically cyanobacteria and algae. For human health are riskier cyanobacteria. How to know?
Whether they are in the water cyanobacteria, or algae, can by the Public Health Institute discern quite well with the help of an ordinary plastic bottles. Then fill the water in which we want to swim, and leave at least 20 minutes on a light stand. In the case that at the levels formed green circle formed green organisms in the form of "needles or chopped green meal" and while the water remains clear, this is most probably of cyanobacteria. If water remains evenly turbid or begins to form larger haze at the bottom, there is likely lashes.
Even simpler is to test when entering the water. By so doing carefully, so that without disturbing sediment from the bottom, we can see that around us do not float in the water small green particles. If yes, this is probably a cyanobacterium, says EAA.
If the desire for a refreshing bath is huge and even water containing cyanobacteria will not deter us from swimming, EAA recommends not spending time in the water more than 10 minutes. This is roughly the time it takes to begin human body receive water from multiple substances and is therefore vulnerable. Indirectly, the maximum for safe bathing also be derived by starting with "soaked skin fingers." If it is possible, according to EAA appropriate after swimming in the contaminated water to shower with clean water to remove any of the skin, algae and cyanobacteria, which to her during swimming clung.
