目的了解进口废旧物品分拣场所气溶胶中微生物的污染状况。方法以六级筛孔撞击式采样器采样与培养分离鉴定方法,进行了现场监测。结果进口废旧物品分拣场所气溶胶中细菌总数和霉菌总数均高于其他场所。检出包括肺炎链球菌在内的30余种细菌。结论进口废旧物品分拣场所气溶胶中微生物污染超标,存在致病微生物,对从业人员存在感染的危险性。
Objective To understand the status of aerosol microbial contamination in imported waste sorting stations. Methods The method of sampling and culture separation of six-level sieve-hole impact sampler was adopted and on-site monitoring was carried out. Results The total number of aerosols and the total number of molds in the sorting places of imported waste articles were higher than those in other places. More than 30 kinds of bacteria including S. pneumoniae were detected. Conclusion The imported aerosol of imported waste material sorting place has exceeded the level of microbial contamination, and there is pathogenic microorganism, which is dangerous to the employees.
