An ADMER (Atmospheric Dispersion Model for Exposure and Risk Assessment), has been developed and tested in the real environment. The ADMER was designed to estimate the long-term average spatiotemporal distribution of the concentrations and depositions of chemicals in comparatively wide areas such as the Kanto region of Japan. The concentrations for a 5×5 km square grid spatial resolution of 6 time zones (i. e., 4 hours average) for a month is available. The model has been well verified. The results of the ADMER in the Kanto region of Japan fit well with the measured data for nitrogen oxides (NO<SUB>x</SUB>) and tetrachloroethylene, as determined in cases of sufficient measurable data. The ADMER includes some useful functions for calculations and for exposure and risk assessment, used for compiling meteorological data and making up gridded emission data for simulations, and for analyzing calculated results visually using several kind of maps, charts and graphs, and estimating the size and location of populations exposed to chemicals.<BR>The ADMER has an MS-Windows graphic user interface which may help not only experts of simulation models, but also risk assessors in government or industry performing simulations. The ADMER will be useful for those risk assessments in which spatiotemporal distributions must be considered.
