ABSTRACT A number of environmental problems are already very serious and they call for immediate attention. The paper mainly concentrates on the impacts of indoor and outdoor air pollutants especially on health, with ultimate result that human hygiene may be deteriorated, economic productivity may be declined and pleasure satisfaction gained from any unspoiled environment often termed as its ‘amenity’ value may also be absent to the present and future human welfare. It has been concluded that intervention of the government has become indispensable to implement strong environmental policy and taking care of growing threats on air pollution in more institutionalized, regular and automatic basis is inevitable.
