Abstract

This paper is aimed at the experimental study on mould contamination status. Mold contamination has seriously threatened residents’ physical and mental health and buildings. However, few experimental studies on mold contamination was made in the built environment under hot and humid climate. We firstly prepared the Sabaurauds agar(SAB) with reference to the national standard and set sampling points by the five-point sampling method in a classroom of USC. Then, we cultured the sample in 28 °C constant temperature condition, counted mould number with plate counting method and referred to the Omeilianski formula to calculate indoor mould concentration. The study found that the average concentration of mould spore in the typical public building was 629cfu/m3, and the exceeding rate was up to 25.8%. The results show that the typical public building environment in Hengyang has serious mould contamination, thus further environmental optimization research is urgently needed.
