- Burning coal and other fossil fuels
- Smelting and refining lead
- Lead-based paint

Lead pollution can be especially harmful to children, as their bodies are still developing and they are more likely to absorb lead from the environment. Lead poisoning can cause a variety of problems in children, including:
- Learning disabilities
