Chemical tankers in Japan transport various kinds and large amount of chemical substance. Some of them have adverse effects to the human health condition. However they are VOC (Volatile Organic Compound) and vapor gas in cargo tanks emits into the atmospheric environment during loading operation and tank cleaning operation that is conducted to avoid contamination with next cargo. In this paper, the emission amount of transported cargoes from chemical tanker in Japan is estimated with calculation models. Furthermore, to evaluate the pollution level of benzene, recognized as carcinogen, caused from chemical tanker activities in the Tokyo bay, the yearly averaged concentration distribution was calculated with atmospheric dispersion analysis. It was found form the analysis that the contribution ratio of chemical tanker to atmospheric concentration of benzene around Tokyo Bay area is 10% approximately.
