Introduction and comparative analysis of indoor air microbial threshold in domestic and foreign standards

 Presents the limit value requirements in indoor microbial contamination concentration standards, research framework and technical roadmaps of developed countries in Europe and America, WHO and other related countries. Provides and compares the limits of indoor microbial contamination concentration in Mainland China, Taiwan China and Hong Kong China. Points out that the concentration limits given by various countries are related to the microbial sampling and analysis methods, microbial species and outdoor microbial contamination concentration. There is still insufficient research on the determination of indoor microbial contamination concentration limits through physiological reaction of human exposure to microbial environment, so as to provide a reference for the formulation and revision of indoor microbial contamination concentration limits in China.
