Exposure Assessment Models

Exposure Assessment Models

Computer Models Developed for Chemical Risk Assessment 
AIST-ADMER (National Institute of Advanced Industrial Science and Technology - Atmospheric Dispersion Model for Exposure and Risk Assessment)
  (English Version)
  A computer model with a set of systems which provides estimation of atmospheric concentrations of chemical substances and human exposure assessment. The purpose of AIST-ADMER is to estimate chemical concentrations in relatively broader areas such as Kanto or Kansai as averages over a long period of time. This model can provide exposure assessment as monthly average in 5 x 5 km mesh and six different time zones.

METI-LIS (Ministry of Economy, Trade and Industry - Low Rise Industrial Source Dispersion MODEL)
  (English Version)
  A user-friendly computer model developed originally by Ministry of Economy, Trade and Industry for wide use not only by researchers and specialists but by manufacturers and citizens. METI-LIS version 2 developed with CRMfs initiative is now available in English also. This model puts special importance to expressing downdraft effect, which often affects dispersion from low emission sources, while it gives solutions of simple Gaussian plume and puff formula for elevated sources. In addition to a short-term estimation with fixed meteorological conditions, a long-term average estimation can be obtained with the model, when hourly meteorological datasets are prepared by users.
AIST-RAMTB, RAMIB (National Institute of Advanced Industrial Science and Technology - Risk Assessment Model Tokyo Bay, Ise Bay)
  (In Japanese only)
  A computer model to assess chemical risks on coastal ecosystems in Japan. The model provides graphic representations of chemical concentrations in sediments, water, absorption to organic matters, and risks to aquatic organisms as aerial distribution or time-course changes at a specific site. 
Currently the risk assessment model for Tokyo Bay (AIST-RAMTB ver 1.1) and Ise Bay (AIST-RAMIB ver. 1.0) are available.
AIST-SHANEL (National Institute of Advanced Industrial Science and Technology - Standardized Hydrology-based AssessmeNt tool for chemical Exposure Load)
  (In Japanese only)
