VII. ISSUES AND PROBLEMS: SOME POLICY RECOMMENDATIONS
K. Clean air
Suspended particulate matter is the most prevalent form of air pollution in Kuala Lumpur, often in combination with high concentrations of sulphur dioxide. That is a mix that is particularly hazardous to health;as urban areas expand, the number of people and sources of pollution threaten to outstrip even determined regulatory efforts. In developing countries, where urban areas are growing at an annual rate of 4 per cent or more, the technical infrastructure for emission control often lags behind growth, and enforcement of the related laws is lax. In the not-too-distant future, clean air may become an increasingly rare resource for a large fraction of the world population.
