某三甲医院牙体牙髓科室内危害因素调查

Environmental Hazards in Stomatology Department of a First Class Hospital

摘要

摘要:
目的了解某三甲医院牙体牙髓科室环境中主要危害因素污染情况。

方法于2012 年4-7 月,在某三甲医院牙体牙髓科室进行甲醛、总挥发性有机化合物(total volatile organic compounds,TVOC)、二氧化碳(carbondioxide,CO₂)、噪声的检测,调查科室空间大小、员工人数、药品等基本信息。

结果牙体牙髓科室内空气中甲醛、TVOC、CO₂ 和噪声总体合格率分别为55.15%、29.09%、96.36%、49.09%。其中早晨、上午、下午3 个时段,TVOC 合格率为32.27%、56.36%、14.55%,甲醛为12.72%、81.82%、70.91%,CO₂ 为100.00%、100.00%、89.09%,噪声为100.00%、21.82%、25.45%,各因素在不同时段的合格率差异有统计学意义(P<0.05)。

结论该院牙体牙髓科工作环境中TVOC的危害程度较高,甲醛浓度和噪音强度对人体有一定的影响,CO₂ 浓度基本达标。

Abstract:
Objective To understand the pollution levels of major hazards in the stomatology department of a first-class hospital.

Methods From April to July 2012, formaldehyde, total volatile organic compounds(TVOC), carbon dioxide (CO₂), and noise in a selected department of stomatology in a first-class general hospital were measured. Room size, number of staff, medicines, and other basic information were also collected.

Results The qualified rates of formaldehyde, TVOC, CO₂, and noise in the department were 55.15%, 29.09%, 96.36%, and 49.09%. In 7:30, 11:00, and 16:00, the qualified rates of TVOC were 32.27%, 56.36%, and 14.55%; 12.72%, 81.82%, and 70.91% for formaldehyde; 100.00%, 100.00%, and 89.09% for CO₂; 100.00%, 21.82%, and 25.45% for noise (all P<0.05).

Conclusion In the selected stomatological workplace, TVOC is the leading health hazard, followed by formaldehyde and noise, and CO₂ concentrations are qualified for relevant standards.
