摘要
目的了解医学院人体解剖室内气态甲醛污染的水平,探讨防治甲醛污染的措施和效果。方法参照我国《公共场所卫生规范》的评价方法进行,分别在使用和不使用通排风空调系统条件下,对人体解剖实验室的甲醛浓度进行了检测。结果在不使用通排风空调系统条件下,室内甲醛的平均污染水平高达8.349 mg/m3,在使用通排风空调系统条件下,室内甲醛浓度水平显著下降,仅为0.501 mg/m3。结论如果不采用通排风空调系统,该医学院人体解剖室空气甲醛污染情况严重,可对教师和学生健康产生危害,而采用通排风空调系统,可以有效防治室内甲醛污染。
Objective To investigate the indoor air formaldehyde pollution in the human anatomy laboratory and to study the control measures and their effects on prevention and control of formaldehyde pollution. Methods The levels of formaldehyde in the air of the human anatomy laboratory with exhaust ventilatary conditional system and without such a system were determined respectively according to the method recommended in the Sanitary Standard of Public Place. Results Without the exhaust ventilatory conditional system, the level of formaldehyde of indoor air reached to 8.349 mg/m3, while the level of formaldehyde was decreased significantly to 0.501 mg/m3 with the system. Conclusion Without the exhaust ventilatory conditional system, the formaldehyde pollution in the air of the human anatomy laboratory was very serious, which might have adverse effects on teachers' and students' health, while with the system, the formaldehyde pollution could be controlled effectively.
