Algal blooms can have negative effects on water quality and aquatic ecosystems. When there is an overgrowth of algae in a body of water, it can lead to decreased oxygen levels through a process called eutrophication. This decrease in oxygen can harm aquatic animals, such as fish and other organisms, leading to fish kills and disruptions in the food chain. Algal blooms can also release toxins that are harmful to other organisms in the ecosystem, including humans who come into contact with contaminated water. Additionally, the presence of algal blooms can block sunlight from reaching underwater plants, affecting their growth and overall ecosystem balance. Overall, algal blooms can disrupt the natural balance of aquatic ecosystems and pose environmental and health risks.
