Different approaches were carried out in this work to assess environmental impacts of a municipal solid waste incinerator. A total of seven sites in the vicinity of the facility were chosen to collect air, banyan leaf and soil samples for analyses of PCDD/Fs by high-resolution gas chromatography/high-resolution mass spectrometry. Based on the PCDD/F concentrations of the three matrices determined at sites upwind, downwind and area of maximum ground concentration, it was found that the environmental impact of the MSWI was not obvious. PCDD/F concentration isopleths of the three environmental compartments coupled with wind rose of the region proved that the influence of the MSWI on the environment was also rather limited. It clarified emission sources by confirming that the PCDD/F concentrations originated mostly from the existing stationary emission sources in the vicinity. Through principal component and cluster analyses on congener profiles, the influence of metallurgical facilities and medical waste incinerators on the ambient air was assessed. Moreover, the modeling of ISCST3 demonstrated also that the contribution of the MSWI to ambient atmospheric PCDD/Fs was minimal. The approaches studied have led to identical conclusions, and thus are useful to cross-evaluate the environmental impact of an MSWI.
本研究采用不同方法评估城市固体废物焚烧炉的环境影响。在该设施附近总共选择了七个地点，采集空气、榕树叶和土壤样本，通过高分辨率气相色谱/高分辨率质谱法分析二噁英/呋喃。根据在上风向、下风向和地面最大浓度区域的三个基质中测定的二噁英/呋喃浓度，发现城市固体废物焚烧炉的环境影响并不明显。三个环境介质的二噁英/呋喃浓度等值线与该地区的风向玫瑰图表明，城市固体废物焚烧炉对环境的影响也相当有限。通过确认二噁英/呋喃浓度主要源自附近现有的固定排放源，明确了排放源。通过对同系物谱进行主成分分析和聚类分析，评估了冶金设施和医疗废物焚烧炉对环境空气的影响。此外，ISCST3模型也表明，城市固体废物焚烧炉对环境大气中二噁英/呋喃的贡献极小。所研究的方法得出了相同的结论，因此对于交叉评估城市固体废物焚烧炉的环境影响很有用。
