摘要
对太原市大气中5种多环芳烃(PAH)的含量进行了测量,并对呼吸道的沉积量进行了估算,结果表明47%~70%的含量富集于<2μm的颗粒物上,5种PAH在呼吸道的总沉积量为12.53μg/d,其中53%沉积于鼻咽区,15%沉积于气管支气管区,32%沉积于肺泡区。
Atmospheric concentrations of five sizes of particles with PAH were determined in Taiyuan,and deposition of PAH in human respiratory tract was estimated.Results showed 47%-70% of air PAH concentrated in the particles less than 2μm in diameter.Total PAH deposition in respiratory tract mea-sured 12.53μg per day,and 53% of them deposited in nasopharyngeal region,65%in tracheobronchial region and 32% in alveoli.
