PAHs in PM10 emitted from different waste incinerators
|
Abstract:
The sampler for PM_(10) from atmosphere was refit,with which a set of PM_(10)(inhaled particulate matter) sampling system applied in flue gas from waste incinerators was established.With the sampling system PM_(10) from 3 different incinerators was sampled respectively.16 kinds of polycyclic aromatic hydrocarbons(PAHs) in PM_(10) were quantified by GC-MS.The mass fraction of PAHs in PM_(10) 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.
