Atmospheric Diffusion of Air Pollution from Ship and Environment Impact Assessment of Coastal Area

Abstract

Concerning the influence of air pollution from ship to coastal regions, author reviewed some calculation cases of air pollutant emission from ship, and some results of atmospheric diffusion simulations in Tokyo Bay. Furthermore, it was considered that the environmental risk assessment becomes important matters, and thusly an example of simple risk evaluation of an anchoring ship was examined. Recognition to risk of harmful chemical substances increases, and necessity to carry out environmental risk evaluation from a ship rises. On this account it is necessary to establish the evaluation method to calculate chemical substances emission from ship, and the method of environment impact assessment of coastal area.
