不同垃圾焚烧炉排放的PM10 中多环芳烃的研究

The sampler for PM10 from atmosphere was refit, with which a set of PM10 (inhaled particulate matter) sampling system applied in flue gas from waste incinerators was established. With the sampling system PM10 from 3 different incinerators was sampled respectively. 16 kinds of polycyclic aromatic hydrocarbons (PAHs) in PM10 were quantified by GC-MS. The mass fraction of PAHs in PM10 and the concentration of PAHs in flue were obtained. The PAHs with different rings were compared. And the toxic parameters of PAHs were analyzed. The result show that most of the PAHs in PM10 is of 4, 5, and 6 rings, while only little PAHs is of 3 and 2 rings. Compared with coalfired power plant, the concentration and toxic parameters of PAHs emitted from waste incinerators are higher.
