OF AIR POLLUTION
17. WHO recommended procedure
1. Containment: Prevention of escape of toxic
substance in atmosphere by enclosure, ventilation
and air cleaning
2. Replacement: replacement of coal, firewood, lead
petrol by new technology e.g. electricity, natural
gases, central heating, solar power etc.
3. Dilution: self cleaning capacity of environment.
E.g. establishment of greenbelt.

OF AIR POLLUTION
18. WHO recommended procedure
4. Legislation: Formulation, implementation
and monitoring of environmental act and
regulation
5. International Action: WHO established an
international network of laboratories for
the monitoring and study of air pollution
