heal.abstract Simultaneous measurements of indoor and outdoor carbon monoxide (CO) concentrations conducted at two different microenvironments in Athens, Greece, using a non-dispersive infrared analyzer, are described in this paper. The two selected microenvironments, an office and a public school, were located in the vicinity of two streets with heavy traffic, near the center of Athens. A statistical correlation analysis of indoor concentration levels with outdoor concentrations monitored at the school and at the office, as well as with meteorological parameters and outdoor concentrations monitored at a fixed monitoring site, was conducted. Hourly indoor concentrations at the office and at the school showed a significant positive correlation with outdoor concentrations measured at both measurement locations (with correlation coefficient values R = 0.74 and R = 0.83 respectively) and at the fixed site (with R = 0.70 and R = 0.67 respectively). The correlation between indoor and outdoor concentrations was even better when hourly concentrations averaged over a 4 h period were considered (correlation coefficient values between indoor and outdoor concentrations measured at the office and at the school were R = 0.85 and R = 0.92 respectively and the correlation coefficient value between indoor and outdoor fixed site concentrations was R = 0.75 for both sites). Mean hourly outdoor concentrations at the fixed monitoring site explained approximately 56% (R = 0.75) of the variation of outdoor concentrations at the office and approximately 68% (R = 0.83) of the variation of outdoor concentrations at the school. The mean daily indoor to outdoor (I/O) ratio ranged between 0.74 and 1.00 at the office and between 0.53 and 0.89 at the school. (C) 2003 Elsevier Science Ltd. All rights reserved. en
