Toxic blue-green algae blooms: a hidden danger at lakes and the seaside

The green film sometimes visible on the surface of lakes and coastal waters in summer is often blue-green algae (cyanobacteria), which produce toxins dangerous to humans and animals. Contact with contaminated water can cause skin irritation, nausea, headaches and, in more serious cases, liver damage. Before swimming, it is worth checking sanitary authority alerts about water quality at a given site.
