ABSTRACT:
A method and apparatus to indicate air quality and locate sources of air pollution utilizing selected living indicator organisms. Air is drawn through a divided chamber or a series of chambers containing indicator organisms. A comparison is made of the growth and physiological health of the organisms in purified air, i. e., where the particulate matter and chemicals have been removed by a series of filters, and of those organisms in air from which only the particulate matter is removed.
