Technologies for Contamination Investigation and Characterization

　　A variety of technologies for investigation and characterization of contamination in geo-environment have been developed at the Geo-Environmental Risk Research Group, AIST. Representative technologies are listed below.

Characterization of toxicity and concentration of different kinds of contaminant using luminescent bacteria
Rapid measurement of radioactive cesium with low concentration in water
Enrichment culture for bacteria applicable for bioremediation
3 dimensional, multicomponent, multiphase simulation of mass transport in geo-environment
Screening survey and rapid mapping of heavy metal contamination
Identification of pollution sources (naturally occurring or artificial pollution)
Testing low-permeability materials with high precision
Diffusion tests for soils or rock samples
Column tests under oxidative or reductive conditions
Leaching test for lead glass
Geoinformatics
Other technologies for characterizing the existing form, transportation behavior of contaminants in geo-environments.
