PM2.5-BOUND PAHS IN THE INDOOR AND OUTDOOR AIR OF NURSERY SCHOOLS IN HANOI, VIETNAM AND HEALTH IMPLICATION

VO THI LE Ha, Nguyen Thi Thu Hien, Minoru Yoneda

Abstract


32 daily PM2.5 samples were collected parallelly outdoor and indoor at sixteen nursery schools in Hanoi.15 individual PAHs were analyzed by GC/MS. Mutagenicpotential (MP) and carcinogenic potential (CP) were  used to evaluate carcinogenic and mutagenic risk contribution. The mean indoor and outdoor PM2.5 concentrations were 38.7μg/m3 and 93.3 μg/m3 respectively, which exceeded WHO Air quality guideline (2004). The mean ∑15PAH concentrations in indoor and outdoor air samples were 267.1 ng/m3 and 843.4 ng/m3, respectively. There was a good correlation of PM2.5 and PAHs between indoors & outdoors. Indoor MEQå7PAHs was 41.4 ng/m3, whilst outdoor MEQå7PAHs was 137.3 ng/m3. The mean level of indoor TEQå15PAH was 64.6 ng/m3, whereas the outdoor TEQå15PAH was208.8 ng/m3. Dibenz(a,h)anthracene (DahA) and benzo(a)pyrene (BaP) are the most contributors on the carcinogenicity and mutagenity of PAHs indoors and outdoors.
