It is obvious that air pollutants soil shirts, penetrate closed windows, irritate the mucous membranes, kill plants, and damage buildings.

In 1968 the Public Health Service was reorganized into three separate health agencies: the Health Services and Mental Health Administration, the National Institutes of Health, and the Consumer Protection and Environmental Health -Service, including the Food and Drug Administration, one of the agencies originally transferred into the Federal Security Agency in 1939. These three health agencies are directed by the assistant secretary for health and scientific affairs, who is aided by the surgeon general of the Public Health Service.
