LIMITED capacity of the atmosphere in the Los Angeles Basin to disperse gaseous wastes accounts for its peculiar susceptibility to smog.
While much has been done to determine actual sources of smog, the author contends that nothing has yet been definitely proved. He tells here of the wide variety of investigative programs-covering meteorology, chemistry, combustion products, aerometric surveys, statistics, physical measurements, rubbish disposal, and other vital apects - undertaken by APF, a nonprofit organization sponsored by local industry, business, and civic groups.
