摘要: |
利用自制被动采样装置,在2011年秋冬季对南京市部分地区室内空气中5种气态多环芳烃(PAHs)(萘、苊烯、苊、芴、菲)进行了为期100d的连续采样检测,被动采样器的采样速率为0.012m3
/d,5种PAHs的回收率在63%~105%之间,方法检出限在1.1~2.4ng范围内。结果表明,南京市5处不同室内环境空气中萘的浓度最高,占总量的90%以上。室内环境空气中5种PAHs的总浓度为230~1 564ng/2m3。住宅内人体对5种PAHs的暴露速率为479~560ng/h。 |

Abstract: |
The current concentration levels of five PAHs (Naphthalene, Acenaphthylene, Acenaphthene, Fluorene and Phenanthrene) in the indoor air was investigated using self prepared passive sampler in buildings with different functions in Nanjing. Through nearly 100 days of continuous passive sampling, the average passive sampling rate of the sampler was 8.42mL/min calculated by active sampling. The recoveries of five PAHs were 64%~105%. The detection limits ranged from 1.1~2.4ng. The results showed that the levels of total five gaseous PAHs (mainly in 2~3 rings)in the indoor air ranged from 230~1 564ng/m3,and more than 90% of the total PAHs was Naphthalene. The potential total exposure rates of the five gaseous PAHs were〖JP〗 479~560ng/h for juvenile and adults (including senior people). |
