CARBON MONOXIDE AS AN INDICATOR OF CIGARETTE-CAUSED POLLUTION LEVELS IN INTERCITY BUSES

In response to increasing public concern about the safety and comfort effects of smoking on intercity buses the Bureau of Motor Carrier Safety conducted tests which were designed to achieve 'worst-case' and 'realistic' carbon monoxide (CO) levels on an intercity bus. It was hypothesized that CO levels would give an indication of the health effect of smoke levels. Under simulated 'worst-case' conditions, which are unlikely to be duplicated in actual service, CO levels were substantially below standards set by the Occupational Safety and Health Administration. However, in the 'worst-case' test four of the six experiment subjects agreed that the smoke level was irritating. In the 'realistic' test, the CO level was 5 ppm above ambient and the accompanying smoke level was not considered to be disturbing. (Author)
