| Research Abstract |
The study developed the understanding of the effect of chemicals used in education and research on the environment and workers. The mass balance study required by PRTR, the system for overall chemicals control, involved survey on the liquid waste and waste effluents, which revealed that volatile compounds such as chloroform were possibly emitted to atmosphere as much as 40 %. In order to minimize the volatile loss during evaporation-collection procedure, the cold trap at atmospheric pressure was proved to be efficient. The health effect on workers were assessed by peak concentration monitoring in addition to normal working area survey, which found frequently relative high concentration exceeding 10-4 risk level. However, the risk should depends on the exposure period as well as the concentration. The risk estimation was facilitated by loss of life expectancy rate with a rectangular approximation method, which proved tobacco smoking is equivalent with benzene inhalation at the concentration of 267 mg/m3.
