The definition of "harmfulness" in a pollutant is not one easily arrived at in our present state of ignorance. This is one very important and basic aspect of man's modern air pollution problem which demands a great deal more investigation.

Corrosion, soiling, plant damage, and other adverse air pollution effects, apart from health effects, are for the most part conceded to be very substantial.

Previous studies of the isotope ratio C13/C12 of carbon in coal, petroleum, wood, and atmospheric carbon dioxide showed a variability which reflected both natural and man-made activities.

Mass Spectrometry - Carbon Isotope Study
Mass Spectrometry - Carbon Isotope Study
Introduction - A study of carbon isotopes in the Los Angeles atmosphere is being performed by Professor S. Epstein at the California Institute of Technology under a research grant from the Air Pollution Foundation.

For example, the C13/C12 ratio of carbon in coal and oil is different from that in atmospheric CO2. Therefore, burned carbonaceous material may be expected to affect this ratio.
For example, the C13/C12 ratio of carbon in coal and oil is different from that in atmospheric CO2. Therefore, burned carbonaceous material may be expected to affect this ratio.
Therefore, a study of these ratios in carbon dioxide found in the Los Angeles atmosphere seems pertinent to an understanding of the processes taking place therein.

During this reporting period, work on this project has been limited to a study of carbon (C13/C12) and oxygen (O18/O16) isotopes in atmospheric carbon dioxide. A series of samples were taken to determine the diurnal effect as well as the geographical distribution over the Los Angeles Basin.
