Science / Medicine : Major Smog-Control Changes Urged
From Times Staff and Wire Reports
Major changes are needed to correct scientific and technical deficiencies in the nation’s regulatory programs to control low-atmosphere ozone, an important component of smog, according to a report from the National Research Council.
Ozone control efforts have been based primarily upon controlling emissions of organic compounds, but the report concluded that in many areas of the country it would be more effective to stress control of nitrogen oxides.
Ozone pollution in the lower atmosphere is produced when sunlight causes nitrogen oxides to react with organic compounds. Nitrogen oxides come mainly from the combustion of fossil fuels by vehicles and power plants.
