| 摘 要： | 采集广州市大气可吸入颗粒物(PM10)样品,并分别对冬、夏两季灰霾和非灰霾期PM10中有机碳(OC)、元素碳(EC)和水溶性离子进行分析。广州市灰霾期大气PM10中的主要化学成分按质量浓度大小排序为OC>NO3->SO24->NH4+>EC(非灰霾期则依次为OC>SO24->EC>NH4+>NO3-),其质量浓度分别为非灰霾期的4.7、12.5、3.7、3.2和2.3倍。相关性分析表明,灰霾期总碳TC(OC+EC)]及NO3-的质量浓度对大气能见度的降低起主要作用,而非灰霾期则主要是TC和SO24-。 |

| Abstract: | PM10 samples were collected in Guangzhou during haze and normal days in the summer and the winter.Water-soluble ions,organic carbon（OC） and element carbon（EC） in PM10 were analyzed.Concentrations of the component in PM10 descended in the order of OCNO-3SO2-4NH＋4EC in haze days,（but OCSO2-4ECNH＋4NO-3 in normal days） which were 4.7,12.5,3.7,3.2 and 2.3 times than that in normal days,respectively.Correlative analysis showed that concentrations of TC（OC＋EC） and NO-3 had significantly negative effect on visibility in haze days,but TC and SO2-4 had that in normal days. |
