微生物气溶胶广泛存在于大气中 其在雾霾天的形成和发展等方面扮演了重要的角色 梳理了雾霾期空气微生物气溶胶的分析鉴定、微生物气溶胶与雾霾天相关性方面的主要研究成果 得出如下结论:空气微生物气溶胶的分析鉴定应制定统一的检测标准 为雾霾天空气微生物的健康风险评估提供科学的定量指标 雾霾期空气微生物气溶胶的浓度普遍高于非霾期 主要表现为真菌气溶胶浓度增加 但微生物的种群丰富度并不会因污染程度的增加而增加 空气微生物气溶胶对人类健 康构成重大威胁 应采取科学措施进行预防
Microbial aerosols widely exist in the atmosphere and play an important role in the formation and development ofsmog days.Based on the analysis and identification of air microbial aerosols in haze period and the correlation between microbial aerosols and haze days this paper combed the main research results of air microbial aerosols in haze period anddrew the following conclusions:the analysis and identification of air microbial aerosols should formulate a unified detectionstandard provide scientific quantitative indicators for the health risk assessment of air microorganisms in haze days theconcentration of microbial aerosol in haze period is generally higher than that in sunny weather which is mainly reflected inthe increase of fungal aerosol concentration but the microbial population richness will not increase with the increase of pol ̄ lution degree airborne microbial aerosols pose a major threat to human health thus we should take scientific measures toprevent the occurrence of diseases.
