This study investigates the ability of fixed location ambient air quality monitoring stations to represent personal environmental exposures to carbon monoxide (CO) accurately. The relationship between residential location, commuting transportation mode, employment location, and time-weighted average human exposure to CO in the metropolitan area was also explored.Personal exposure was measured by equipping 66 nonsmoking volunteers in the Boston area with portable CO samplers which employ an electrochemical sensing method. Measurements at six fixed monitoring stations operated by the Massachusetts Bureau of Air Quality control underestimated mean 1 hour personal exposure ba a factor of 1.3 to 2.1. However, alveolar air sample s showed no significant increase in blood carboxyhemoglobin (COHb) levels due to commuting exposure. Fixed location measurements were representative of 8 hour average population exposure.
