摘要
为科学评估PM_(2.5)对生物体综合生物效应,研究建立了利用费氏弧菌检测PM_(2.5)水溶性提取液的毒性测试方法,确立了PM_(2.5)样品提取液发光细菌毒性测试实验质量控制办法。对春节烟花爆竹燃放和沙尘污染过程的PM_(2.5)实样测试表明:烟花爆竹燃放期间的PM_(2.5)样品提取液发光抑制率值与微量金属元素等有毒有害组分浓度显著相关;沙尘污染期间的PM_(2.5)样本提取液中地壳元素浓度和发光抑制率值显著不相关。
The fine particulate matter（ PM2.5） can be breathed into lungs and threatens human health. For scientific assessment of the comprehensive biological effects of PM2.5,a simple method with the laboratory quality control standards for testing the toxicity of the PM2.5water-soluble components was established by using Vibrio fischeri as an indicator bacterium. A series of toxicity tests performed on this luminescent bacterium were carried out with thePM2.5samples from the Spring Festival fireworks and the dust pollution,respectively. Our results showed that the luminous inhibition rate had a significant correlation with the concentrations of poisonous and harmful trace metal elements discharged by the fireworks and crackers during the Spring Festival,whereas the luminous inhibition rate was not associated with the concentrations of the earth＇s crust elements in the PM2.5extracting solution.
