toxic algae

Toxic algae are types of microscopic aquatic plants that can produce harmful substances called toxins. When these algae grow excessively—often due to nutrient pollution from fertilizers—they form "algal blooms" that can discolor water. Some of these toxins can be dangerous to humans, pets, and wildlife if ingested or contacted, causing health issues like skin irritation, respiratory problems, or more severe illnesses. These blooms can also produce dead zones by depleting oxygen in the water, harming aquatic ecosystems. Managing nutrient input and monitoring water quality are essential for controlling toxic algae and protecting public health and the environment.
