Photochemical smog standards--practicability or purism: an evaluation of health risk in Sydney

The photochemical smog conditions in Sydney are related to the effects on health, real and potential. Perspectives are presented with regard to the long-range goals of the World Health Organization, past and current United States Environmental Protection Agency standards, and current New South Wales prudent and actual aspirations in the short and long term. The need for practicable, rather than puritanical, goals in relation to possible adverse health effects is emphasized. The view is expressed that, while no significant ill health will be induced in current and improving atmospheric conditions, the aesthetic appearance of Sydney is unacceptable and therefore is detrimental to the feelings and well-being which are part of health.
