2.6 Principles of pollution management
Explain the differences between a hazard, a contaminant and a pollutant.
A hazard is anything that harms our health. A contaminant is something introduced to the environment (air and water) that may or may not pose a significant health risk. A pollutant is a contaminant introduced into the environment that adversely affects animal and human life.
There are two main approaches to pollution management:
- Pollution prevention: focuses on stopping pollution being produced in the first place, or reducing any waste generation at the source.
- Pollution control: those measures taken to control pollution and wastes after they have been generated or produced.
