Abstract: Aim: The aims of this study were to investigate the relationship between pregnant women''s personal exposures to NO x , NO2, PM2.5 concentration and absorbance as a marker for black carbon and their indoor and outdoor concentration levels at their residence, and also to identify predictors of personal exposure and indoor levels using questionnaire and time activity data. Method: We recruited 54 pregnant women in Barcelona who carried a personal PM2.5 sampler for two days and NO x /NO2 passive badges for one week, while indoor and outdoor PM2.5 and NO x /NO2 levels at their residence were simultaneously measured. Time activity and house characteristics were recorded. Gravimetry determinations for PM2.5 concentration and absorbance measurements were carried out on the PM2.5 filter samples. Results: Levels of personal exposure to NO x , PM2.5 and absorbance were slightly higher than indoor and outdoor levels (geometric mean of personal NO x = 61.9 vs indoor NO x = 60.6 μg m−3), while for NO2 the indoor levels were slightly higher than the personal ones. Generally, there was a high statistically significant correlation between personal exposure and indoor levels (Spearman''s r between 0.78 and 0.84). Women spent more than 60% of their time indoors at home. Ventilation of the house by opening the windows, the time spent cooking and indicators for traffic intensity were re-occurring statistically significant determinants of the personal and indoor pollutants levels with models for NO x explaining the 55% and 60% of the variability respectively, and models for NO2 explaining the 39% and 16% of the variability respectively. Models for PM2.5 and absorbance explained the least of the variability. Conclusion: Our findings improve the current understanding of the characterization and inter-associations between personal, indoor and outdoor pollution levels among pregnant women. Variability in personal and indoor NO x and to a lesser extent NO2 levels could be explained well, but not the variability in PM2.5 could be explained. [Copyright &y& Elsevier] |
