The purpose of this study was to examine the occurrence level of harmful chemical substance and the riskiness caused by it at university laboratory, which had been faintly interested in safe health management. It measured and analyzed indoor pollutants by academic department targeting K university where is located in Seoul Metropolis for 6 days starting from May 26, 2010. As a result, the appearance of being furnished with MSDS, the appearance of installing the exposure-reduction facilities, and the present status of supplying protective equipment in order to grasp the present status of managing harmful chemical substance at university laboratory were relatively good in management at the Dept. of Chemistry, the Dept. of Physics, and the Dept. of Medical Science, which are basic science laboratories. The activity for managing harmful chemical substance in the Dept. of Dental Medicine and the Dept. of Fine Arts was surveyed to be insufficient. Also, the concentration of formaldehyde and TVOCs(total volatile organic compounds) inside laboratory was detected noticeably highly in the Dept. of Fine Arts compared to other laboratories. The concentration of formaldehyde in a group, which was collectivized by similar academic department, was indicated to be higher in other academic departments including the Dept. of Fine Arts and the Dept. of Life Science, thereby having shown significant difference. The concentration of formaldehyde and TVOCs showed significant difference at the laboratory without installation compared to the laboratory with installation of fume hood. Seeing the above results, it could be known that a whole drop in recognition on influence of chemical upon health leads to being able to increase occurrence level of hazardous factor due to being insufficient in activity of protecting exposure to chemical substance.
