kékalgák

Kékalgák is a term used to refer to blue-green algae, which are actually a type of bacteria called cyanobacteria. These microorganisms are photosynthetic, meaning they produce their own food using sunlight, carbon dioxide, and water. They are found in a wide variety of environments, including freshwater, saltwater, and even in soil. Cyanobacteria play a crucial role in ecosystems, as they are often primary producers, forming the base of food webs. They also contribute to oxygen production in the atmosphere.

In some cases, particularly in nutrient-rich water bodies, cyanobacteria can multiply rapidly, leading to algal blooms. These blooms can sometimes produce toxins that are harmful to humans, animals, and aquatic life. Exposure to these toxins can occur through direct contact with contaminated water, ingestion of contaminated water, or consumption of contaminated fish or shellfish. Symptoms of exposure can vary depending on the type of toxin and the level of exposure, but may include skin irritation, gastrointestinal distress, or more severe neurological effects. Public health agencies often monitor water bodies for harmful algal blooms and issue advisories when necessary.
