中文摘要：
用ICP-MS测定K,Al,Fe,Mn,Cu,Pb和Zn等27种元素的浓度,讨论了这些元素在灰霾与非灰霾期的浓度特征.结果表明,广州市大气PM10中无机元素的质量浓度在灰霾期要高于非灰霾期,同时灰霾与非灰霾期间所测元素的分布特征基本一致,说明灰霾与非灰霾期间无机元素的来源基本上是一致的.富集因子法分析结果显示,来源于人为活动的Zn,Pb,As和Cu在灰霾期更容易富集.
英文摘要：
PM10 samples in the winter of 2005 were collected in Wushan, Guangzhou. Samples of discontinuous 12 days before and after the serious haze period were analyzed.About 27 inorganic elements were determined using the inductive couple plasma-mass spectrometry（ICP-MS）techniques. The results showed that concentrations of inorganic elements in haze days were higher than normal days. In addition, distributions of the measured elements were similar between haze and normal days, which indicated that the inorganic elements in haze and normal days came from similar particulate emission sources. Enrichment factors（EF）for inorganic elements showed that elements from anthropogenic origins （Zn, Pb, As and Cu） were highly enriched in haze days.
