Abstract: | A unique air handling facility was designed to introduce up to 12,000 cfm of street level air into laminar flow animal exposure chambers in an unaltered state except for the heating and cooling necessary in extreme weather to provide the animals with an habitable climate. The facility was built to determine the possible effect of street level exhaust emissions on the health of the general population. Another objective was to determine, by means of direct reading and recording instruments, the concentration of contaminants such as carbon monoxide, carbon dioxide, aerosols, nitrogen oxides, total oxidant, and unburned hydrocarbons. |
