A Combined Index for Measurement of Total Air Pollution: Effects of Changing Air Quality Standards,l policy must be able to trade off one pollutant against another, always being aware of the effect of a change in one pollutant level on overall air quality. An index called “pindex” is proposed in which six pollutants, a synergism, and photochemical effects are combined to yield a measure of total

Atmospheric Ozone Determination by Amperometry and Colorimetry,calibration of oxidant and ozone analyzers as well as to collect air quality data. The term “oxidant” refers to all substances present in the sampled air that oxidize potassium iodide (KI) to form iodine (I.) such as ozone (O.), nitrogen dioxide (NO.), and organic peroxides. Specific spectroscopic m

The Determination of Trace Metals in Air,he ultimate control of pollution requires reliable analytical methods capable of accurately delineating the problem in all of its aspects. All too often “black boxes” are used to measure pollutants. The instruments used may provide valid information but more often than not they measure some general,

Studies of Sulfur Compounds Adsorbed on Smoke Particles and Other Solids by Photoelectron Spectrosch from a power plant and smoke particles from a home furnace have been analyzed. It is shown that the oxidation states of sulfur in compounds adsorbed on these solids can be determined. The use of photoelectron spectroscopy for studying the effects of combustion variables and downwind conditions on
