This study was conducted to correlate the personal formaldehyde (FA) exposure levels of instructors and students with the indoor FA concentrations in gross anatomy laboratory at King Saud University. The personal FA levels of instructors and students are higher than the indoor FA concentration in the gross anatomy laboratory.
The gross anatomy laboratory at college of medicine, King Saud University Riyadh, was observed for indoor FA concentration and the personal exposure levels of instructors and the medical students during the 4th, 10th and 14th weeks of the dissection sessions. All air samples were collected by the diffusive sampling device and analyzed by using high performance liquid chromatography (HPLC).
The personal exposure level of FA was higher than the indoor concentration, and the personal exposure levels of instructors were higher than that of the students. The concentration of FA was also higher in the center of the room than the corners and near the doors.
Both the indoor FA concentrations and personal FA exposure levels are higher near the dissecting table than at locations away from it during the gross anatomy laboratory sessions. Thus, the instructors and students are exposed to the higher concentration of FA than the general population.
本研究旨在探讨沙特国王大学医学院大体解剖实验室中教师和学生的个人甲醛(FA)暴露水平与室内 FA 浓度之间的相关性。教师和学生的个人 FA 水平高于大体解剖实验室的室内 FA 浓度。
观察沙特国王大学利雅得医学院的大体解剖实验室,在解剖课程的第 4、10 和 14 周期间,测量室内 FA 浓度以及教师和医学生的个人暴露水平。使用高效液相色谱法(HPLC),通过扩散采样装置收集所有空气样本进行分析。
个人 FA 暴露水平高于室内浓度,教师的个人暴露水平高于学生。室内 FA 浓度在房间中心高于角落和靠近门的位置。
在大体解剖实验室期间,靠近解剖台的室内 FA 浓度和个人 FA 暴露水平均高于远离解剖台的位置。因此,教师和学生接触的 FA 浓度高于一般人群。
