工作场所与居室粉螨变应原含量相关性研究

Study on correlation of acarid mites allergens concentrations between working place and dwelling

目的:探讨特定职业人群工作场所与居室粉螨变应原的相关性。方法:选取面粉、中药材及粮食加工人员(粉螨变应原暴露人群)各10名为实验组,对其工作场所的浮尘、落尘及居室内地板尘、床铺尘进行取样,另取本校教职工10名为对照,同样取样共160份。ELISA法检测样品中粉螨变应原的含量。结果:实验组工作场所变应原含量明显高于居室内;浮尘变应原含量与床铺尘、地板尘具有相关性(rs=0.40,P<0.01;rs=0.32,P<0.05),对照组工作场所与居室内变应原含量无明显差异,浮尘与床铺尘变应原含量无显著相关性。结论:粉螨变应原暴露人群的工作场所及居室内粉螨变应原污染严重,并存在从工作场所向居室的变应原转移。

Objective：To explore the correlation of acarid mites allergens between working place and dwelling. Methods：To select 10 processing workers from different occupations with exposure of acarid mites allergens set as experimental group respectively, and 10 teachers from our college set as control group. The allergens concentrations of 160 specimen were measured by ELISA from the airborne and settled dust in working place, mattresses and floor dust indoor. Results：The highest concentrations of allergens in airborne and settled dust was 734. 5 ±528.5 and 844. 8 ±687. 1 μg/g, the noticeable ones in mattress and floor dust was 85. 1 ± 82.9 and 53. 5 ± 58. 3 μg/g, airborne dust concentrations of allergens correlates with either mattresses or floor dust （ r6 = 0.40, P 〈 0. 01 ; r6 = 0. 32, P 〈 0. 05 ） in experimental group, but never in control group. Conclusion： The concentration of acarid mites allergens is serious in working place and dwelling of exposure group, and the allergens transport from working place to dwelling must be prevented.
