摘要
本工作用平皿沉降法在北京市西单观测了大气真菌粒子的沉降量。结果表明,大气真菌粒子的年平均沉降量为11.1个/皿·5分;一天内,大气真菌粒子沉降量出现7:00、19:00二个高峰时和13:00、凌晨4:00二个低峰时。结果同时表明,大气真菌粒子的沉降量夏季高,秋季低;白天与夜间的沉降量变化不大。
We investigated the percipitation of airborne fungi particles with gravity plates at xidan area of Beijing. Our results show that, 1, The yearly average of the precipitation of airborne fungi particles is 11.0/dish. 5 min; 2,The highest precipitation occurs at 7:00 and 19:00 and the lowest precipitation at 4:00 and 13:00 in one day time; 3, The precipitation is high in the summer and low at the fall; 4, The significant difference of the precipitation between day and night is not observed in this study.
