Question

Explain three effects of water pollutants

Answer 1

Answer:

On human health. To put it bluntly: Water pollution kills. ... Waterborne pathogens, in the form of disease-causing bacteria and viruses from human and animal waste, are a major cause of illness from contaminated drinking water. Diseases spread by unsafe water include cholera, giardia, and typhoid.

Answer 2

• Diseases: Drinking or consuming polluted water in any form has a wide range of negative health consequences in humans. Typhoid fever, cholera, hepatitis, and other diseases are all caused by it.
• Ecosystem destruction: Ecosystems are extremely dynamic and respond to even minor environmental changes. If left unchecked, water pollution can bring down an entire ecosystem.
• Eutrophication occurs when chemicals in a body of water promote algae growth. On the surface of the pond or lake, algae form a layer. Bacteria feed on the algae, which reduces the amount of oxygen in the water body and has a negative impact on the aquatic life.
• When toxins and pollutants in the water are consumed by aquatic animals (fish, shellfish, etc.) and then consumed by humans, the food chain is disrupted.
