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.
