Atmospheric Environment Team (AET), led by Dr. Hiroshi Yoshikado, consists of four members. In October 2004, the AET was re-organized, and the Exposure Modeling Team (EMT) was separated from the AET, but they have been collaborating to carry out the primary missions described below.
Many chemical substances that may cause adverse human health effects are released into the atmosphere, and therefore, one of the main objectives of the CRM is to investigate their behaviors in the atmosphere and to develop methodologies and techniques for estimation and evaluation of chemical concentrations in the ambient air and their human exposure risks. The AET plays the main part of this research and development.
Major research subjects of the team are as follows:
1) Techniques to search for emission sources and to estimate accurate emission amount of chemical substances;
2) Modeling of atmospheric diffusion, transport and formation/transformation process of chemical substances;
3) Evaluation of human exposure to the chemical substances from the concentrations obtained by the above technique and tools;
4) Emission control strategies based on the assessment of chemical dispersion/exposure levels; and
5) Risk assessment of chemical substances mainly transported and exposed via the atmosphere.
It is particularly important to use accurate models to simulate the chemical dispersion in the atmosphere and resultant concentrations at arbitrary locations. The AET plans to provide the results of research for public use in formats such as user-friendly software for PCs or a guideline manual.
