Pollution by Hazardous Waste
Love Canal highlighted the problem of pollution by hazardous waste. Hazardous waste is any waste that is dangerous to the health of people or the environment. It may be dangerous because it is toxic, corrosive, flammable, or explosive. Hazardous waste can contaminate the land, soil and water.
- Toxic waste is poisonous. Toxic waste may cause cancer or birth defects in people. It may also harm other living things.
- Corrosive waste is highly reactive with other substances. Corrosive waste may cause burns or destroy other materials that it touches.
- Flammable waste can burn easily. It may also give off harmful fumes when it burns.
- Explosive waste is likely to explode. The risk of explosion may be greater if the waste is mixed with other substances.
