摘要
[目的 ]了解医院生活垃圾的生物性污染状况。 [方法 ]采集不同等级医院的 10 0份垃圾样品 ,检验其细菌总数、大肠菌群、肠道致病菌和乙肝表面抗原 (HBs Ag) ,并与居民区的 40份垃圾样品做对照。 [结果 ]医院生活垃圾细菌总数 :6 .0× 10 7～ 3.4× 10 9个 / kg,大肠菌群 >2 .5× 10 4个 / kg;居民区生活垃圾细菌总数 :4.7× 10 7～ 1.4× 10 9个 / kg,大肠菌群 >2 .5× 10 4个 / kg,两者差异不显著 (P>0 .0 5 )。医院生活垃圾肠道致病菌检出率 13.6 4%～18.91% ,居民区生活垃圾未检出肠道致病菌 ,两者差异显著 (P<0 .0 1)。 [结论 ]医院生活垃圾存在生物性污染 ,对环境和人群健康构成威胁 ,应加强管理。
Objective]To understand the biological pollution of domestic rubbish in hospital [Methods]The total count of bacteria,the count of coliform bacteria,intestinal pathogens and hapatitis B virus surface antigen(HBsAg) of 100 rubbish samples collected from several hospitals with different grades were determined,and were compared with the relative data obtained from 40 rubbish samples as controls,collected from several residential districts [Results]The detected total count of bacteria and coliform bacteria were 6 0×10 7～3 4×10 9/kg and >2 5×10 4/kg for hospital domestic rubbish respectively, and 4 7×10 7～1 4×10 9/kg and >2 5×10 4/kg for residential district domestic rubbish respectively,the relative data revealed no significant differences between those two kinds of rubbish ( P>0 05 ) The positive rates of intestinal pathogens presented significant differences between the hospital domestic rubbish (13 64%~18 91%) and residential domestic rubbish (no positive foundings)( P<0 01 ) [Conclusion]Hospital domestic rubbish presented biological pollution,which could destroy the environment and human health,and should be more strictly managed and controlled
