Kékalgás is a term used to describe the phenomenon of blue-green algae blooming in bodies of water. These blooms are actually caused by cyanobacteria, a type of bacteria that photosynthesizes and can appear in various colors, including blue and green. They are often indicative of eutrophication, a process where excessive nutrients, such as nitrogen and phosphorus, enter the water.
These nutrient overloads typically stem from human activities like agricultural runoff containing fertilizers and sewage discharge.
Kékalgás can have significant ecological impacts. The dense blooms can block sunlight from reaching submerged aquatic
