Study Notes

Pollution and Its Effects

Pollution is generally defined as the introduction of contaminants into the environment, causing harm to humans, wildlife, and the ecosystem as a whole.

Biological Magnification and Trophic Transfer

Biological magnification is the process by which pollutants increase in concentration as they move up the food chain.
Trophic transfer occurs when pollutants are transferred from one species to another through consumption.

Common Pollutants and Water Pollution

Common pollutants that can affect the environment adversely include:
- Chemicals
- Heavy metals
- Pesticides
- Industrial waste
Water pollution occurs when pollutants enter water bodies, such as rivers, lakes, and oceans, through human activities or natural events.
