目的对6家医院牙科诊室和病理室空气中汞和甲醛进行检测。方法用大型气泡吸收管采集空气样品,氢化物原子荧光光谱法测定空气中汞的含量,酚试剂分光光度法测定甲醛含量。结果 6所医院牙科诊室空气中汞浓度为:0.0013～0.0054μg/m3,均未超出国家标准;6家医院病理室空气中甲醛浓度为0.02～1.90 mg/m3,有2家医院病理室空气中甲醛浓度超出了国家卫生标准。结论应加强对汞和甲醛这两种污染物的防护,减少摄入汞和甲醛的机会,保护医务工作者的健康。
Objective To test the mercury and formaldehyde in the air of 6 hospital dental offices and pathology rooms. Methods Air samples were collected with a large bubble absorber tube, the content of mercury in the air was measured by hydride atomic fluorescence spectrometry, and the formaldehyde content was measured by phenol reagent spectrophotometry. Results The air mercury concentrations in the dental clinics of the six hospitals were 0.0013 ~ 0.0054 μg / m3, all of which did not exceed the national standards. The concentrations of formaldehyde in the pathological air of the six hospitals ranged from 0.02 to 1.90 mg / m3. There were two hospital pathological air Formaldehyde concentration beyond the national health standards. Conclusion The protection of both mercury and formaldehyde pollutants should be strengthened, reducing the chance of mercury and formaldehyde ingestion and protecting the health of medical workers.
