Most of chemicals have acute or chronic toxicity to people or other living things. Risk assessment of chemicals is a basic demand to build up environmental management systems even in educational courses of university where many chemicals are used in experimental subjects of chemistry. Authors conducted a case study on personal exposure of ammonia used in the educational experiment on chemistry. As a result, students felt uncomfortable by odor of ammonia during the experiment. In this study, we attempted to evaluate an effect of risk communication on personal exposure of chemicals in educational courses of university. The students were divided nto two groups : uncommunicated and communicated well on the risk of ammonia, measuring personal exposure concentration of ammonia by a diffusion type personal sampler. As a result, exposure concentrations of communicated groups were lower than those of uncommunication groups. Furthermore, we estimated acute exposure concentration from collected amount of ammonia for risk analysis. If communicated well, the concentration would not exceed the OSHA guideline value (35 ppm) even when the exposure time was just 3 minutes. This suggested a possibility of decreasing the exposure concentration of chemicals by risk communication.
