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.
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 CRMfs 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.
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.
