| Abstract: |
| Objective To look for more stable method for measuring fungal counts in air. Methods In different sampling points and time, the natural precipitation method and impacting method were used to gather fungus in air at the same time. There were three parallel samples in each treatment group. Fungal counts that cultured in plates were tested by Grubbs' test method and outliers were eliminated. Fungal counts of air were calculated based on the means of parallel samples. Variation coefficient of two measurements’ fungal counts that cultured in plates and influences of sampling time on the calculation result were compared. Results Variation coefficient of impacting method was smaller, and sampling time had less influence on impacting method within 15 minutes. Conclusion The impacting method is more stable to measure fungal counts of air. |
