title: [Pilot study on PAHs of the atmosphere around the refuse incineration plant based on the technology of passive sampling].
abstract: Waste incineration is the main source of PAHs pollution of the atmosphere. In order to monitor the PAHs produced during the process of incineration, methods of quantitatively analysis for the PAHs of the atmosphere around the refuse incineration plant has been used on the basis of passive sampling technology. The result shows that the quantum of PAHs ranged 146.29-396.30 ng x d(-1), among which gaseous phase ranged 128.03-377.05 ng x d(-1), particulate phase ranged 10.698-19.251 ng x d(-1). Low ring compounds like phenanthrene, fluoranthene, fluorene make up the most of PAHs of gaseous phase in the atmosphere, in which phenanthrene reaches up to 55.1%. Pine needles are picked as passive plant samples, and the result shows that the concentration of PAHs in pine needles ranged 651.88-1 044.43 ng x g(-1). The distribution characteristics of PAHs in the soil reveals that the concentration of PAHs in the soil ranged 35.04-998.89 ng x g(-1). The PAHs distributions in passive sampling, pines and soil are extremely similar, which indicates that the passive samplings can reflect the real PAHs accumulation conditions in the environment. Besides, the results of passive sampling were compared with active sampling, and both accumulation abilities work almost the same.
