| 摘 要： | 为科学评估PM_(2.5)对生物体的综合生物效应,利用费氏弧菌检测了PM_(2.5)水溶性提取液的光抑制效应,统计分析了227组PM_(2.5)主要组分与发光抑制率的相关关系.实验结果表明:PM_(2.5)水溶性提取液的发光抑制率值与OC、NO-3、EC和微量元素等组分浓度显著相关,相关系数从高到低的排序为:OC微量元素ECNO-3(p0.01).PM_(2.5)中,主要来自燃煤、交通燃油、生物质燃烧及冶金工业污染源排放的组分(苯并(a)芘、Cl-、OC、Cu、K+、Mn、Zn、EC、Pb、Se、F-等)浓度与发光抑制率显著相关.此外,二次来源的NO-3、NH+4等组分浓度与发光抑制率在冬季和春季显著相关.

| Abstract: | Air pollution exposure is associated with a range of adverse health impacts. For scientific assessment of the comprehensive biological effects of PM2.5, a series of toxicity tests with the PM2.5 water-soluble components were performed on luminescent bacterium by using Vibrio fischeri as an indicator bacterium for 1 year in 2014. The relationship between the luminous inhibition rate and the concentration of chemical components in 227 PM2.5 samples were analyzed. Our results showed that the luminous inhibition rate had a significant correlation with the concentration of chemical components in PM2.5. The correlation coefficient followed the order of OC > trace metal elements > EC > NO3- (p<0.01). The concentration of PM2.5 constituents including benzo (a) pyrene, Cl-, OC, Cu, K+, Mn, Zn, EC, Pb, Se, and F-discharged by the combustions of coal and biomass, traffic emissions, and metallurgical industry emissions had a significant correlation with the luminous inhibition rate. We also observed a high correlation between the luminous inhibition rate and the concentration of NO3- and NH4+ formed by secondary processes in winter and spring. |
