目的研究室内空气中PM_(2.5)污染状况,为室内人群暴露提供数据支持;方法 2013年5月-2014年4月,利用SKC采样泵采集样品,通过重量法计算空气中PM_(2.5)质量浓度。结果居室、学校室内、办公室室内空气中PM_(2.5)质量浓度未超过国家标准,I/O比值显示室内、室外空气中PM_(2.5)质量浓度相关。结论室内场所空气中PM_(2.5)质量浓度低于室外,在雾霾天气状况时室内空气PM_(2.5)质量浓度显著升高,应加强室外空气中PM_(2.5)控制。
Objective To study PM_ (2.5) pollution in indoor air and provide data support for indoor population exposure.Methods From May 2013 to April 2014, samples were collected by SKC sampling pump and PM_ (2.5) concentration in air was calculated by gravimetric method . Results The PM_ (2.5) concentration in indoor air, indoor air and office air did not exceed the national standard, and the I / O ratio showed PM_ (2.5) mass concentration in indoor and outdoor air. Conclusion PM_ (2.5) mass concentration in indoor air is lower than that in outdoor air. PM_ (2.5) mass concentration in indoor air is significantly increased during haze weather, PM_ (2.5) control should be strengthened in outdoor air.
