IMO (International Maritime Organization) recognized that chronic exposure to benzene vapor in air may cause leukemia even if the concentration is very low, such as a few parts per million. Chemical tankers in Japan, however, transport various kinds of chemical substances over 15 million tons per year. Not only benzene but also other chemicals transported by marine vessels have adverse effects to the human health condition. Considering this background, the purpose of this report is to evaluate the emission amount of the cargo vapors and the health risks posed by the exposure, and to pursue the possibility of a vapor recovery system. To achieve the purpose, we conducted a research composed of following three sub-themes. The first one is to make clear the pollution level on chemical tankers by conducting field measurements. We collected working environmental concentration, exposure concentration of tanker crews and emission concentration during loading operation. The second is evaluation of pollution level by a human health risk analysis with LLE (Loss of Life Expectancy). We computed LLEs of seven typical chemical substances transported as cargoes in Japan and summarized in the form of a "risk ranking" for tanker crews. The third is to collect fundamental data to develop an air pollution control system recovering the vapor gas discharged from cargo tank during tank cleaning or gas free operation.
