利用2012年-2014年在北仑城区的黒碳气溶胶及相关的能见度、SO2、NO2、CO、O3、PM1、PM2.5因子的监测结果,研究区域黒碳气溶胶的污染特征及与其他相关因子的关系等。结果表明,黒碳气溶胶随着浓度的不同组分会有所差异。另外,区域内的黒碳气溶胶的本底值为1.25μg/m3,在国内大城市中处于相对低位,但远高于全球本底值;黒碳气溶胶对消光的贡献为12.13%;与SO2等的相关性分析表明,其与PM2.5、PM 1、NO 2均为强正相关,与SO 2和CO均为中等强度正相关,而与O 3则显示了负的指数相关。
利用2012年-2014年在北崙城區的黒碳氣溶膠及相關的能見度、SO2、NO2、CO、O3、PM1、PM2.5因子的鑑測結果,研究區域黒碳氣溶膠的汙染特徵及與其他相關因子的關繫等。結果錶明,黒碳氣溶膠隨著濃度的不同組分會有所差異。另外,區域內的黒碳氣溶膠的本底值為1.25μg/m3,在國內大城市中處于相對低位,但遠高于全毬本底值;黒碳氣溶膠對消光的貢獻為12.13%;與SO2等的相關性分析錶明,其與PM2.5、PM 1、NO 2均為彊正相關,與SO 2和CO均為中等彊度正相關,而與O 3則顯示瞭負的指數相關。

Based on the monitoring data of black carbon aerosol(BC), PM2.5, PM1, SO2, NO2, CO, O3 and visibility at Beilun from 2012 to 2014, this paper analyzed the characteristics of BC and influencing factors.The results show that the compo-sition was different in the different BC mass concentration.The base BC mass concentration was 1.25 μg/m3 , which was lower than most of the cities in China, but was higher than global base.The extinction proportion of BC was 12.13%, and that was higher in winter than in summer.There were strongly positive correlations between BC and PM 2.5, PM 1, NO 2, and positive corre-lations between BC and SO 2, CO also existed, furthermore, a negative exponent correlation was found between BC and O 3 .
