Transcript of The Movement of Waterborne Pollutants

The Movement of Waterborne Pollutants What is a Waterborne Pollutant? A substance that is released into a body of water, where it becomes dissolved or suspended in the water. How Do They Enter the Environment? Discharge of sewage water.
Domestic and industrial wastes.
Heavy metals from mining and smelting operations.
Accidentally, for example oil spills and pesticides that enter surface water easily in run-off. Why Are They Bad?
Cause many diseases.
Persistant pollutants can end up in the food chain and become a toxic danger.
They can travel great distances through organisms, and end up in the food chain of non-polluted areas.
In rivers.
In seas and oceans pollutants are transported through currents.
Not so much in lakes (Pollutants usually get deposited in the lakebed). How Are They Transported? Some Sources of Waterborne Pollutants Factories, refineries, waste treatment plants.
Tailing Ponds (Alberta Oil Sands).
Fertilizers and pesticides that enter the environment through agricultural practices. Thanks...
