海陸風を含む模擬気象場におけるパフ・プルームモデルを用いた大気汚染物質リスク評価モデルの検証

Abstract

Environmental risk assessments will be necessary in the near future when every facility that may exhaust pollutants such as a chemical plant or a waste disposal plant is constructed. The puff-plume model is commonly used for the environmental assessments of atmospheric pollutions in Japan. Although the puff-plume model is applicable to calculating pollutants concentration in relatively simple wind fields, we have to examine whether it satisfies requirements of the risk assessment model. The aim of this study is to verify the model using common weather conditions simulated by a three dimensional atmospheric model. Pollutants concentrations were calculated by the puff-plume model and compared to those by three-dimensional simulations. The puff-plume model doesn't calculate pollutants concentrations accurately in the bay area under a weather condition that sea and land breeze is rising.
