Tóm tắt: Thirty two daily indoor and outdoor PM2.5 samples at sixteen nursery schools in Ha Noi were taken from March to April 2018.15 individual PAHs were analyzed by GC/MS. Mutagenic potential (MP) and carcinogenic potential (CP) were used to evaluate carcinogenic and mutagenic risk contribution. The average PM2.5 concentrations were 38.7μg/m3 for indoor air and 93.3 μg/m3 for out door one, which exceeded WHO Air quality guideline (2004) for ambient air. The mean concentrations of indoor and outdoor 15PAHs were267.1ng/m3 and 843.4ng/m3, respectively. There was a good correlation between indoors and outdoors for both PM2.5 and PAHs. Indoor MEQ7PAHs was 41.4 ng/m3, whilst outdoor MEQ7PAHs was137.3 ng/m3. The mean level of indoor TEQ15PAH was 64.6 ng/m3, where as the outdoor TEQ15PAH was 208.8 ng/m3. Dibenz(a,h)anthracene (DahA) and benzo(a)pyrene (BaP) were the most contributors among indoor and outdoor PAHs to the carcinogenicity and mutagenity.
