Chemical Substance Database (WebKis-Plus) (Japanese)

Chemical Substance Database (WebKis-Plus)

WebKis-Plus database contains information on physicochemical properties, regulations (related mainly to environmental pollution), environmental concentrations from surveys conducted by the Ministry of the Environment, volumes of chemical substances manufactured or imported, volumes of agricultural chemicals shipped to each Japanese prefecture, Pollutant Release and Transfer Register (PRTR) emissions and transportation amounts, the results of risk assessments performed by several external organizations, and other relevant information related to chemical substances. (Japanese only)
Grid-Catchment Integrated Environmental Modeling System (G-CIEMS) (Japanese)

Grid-Catchment Integrated Environmental Modeling System (G-CIEMS)

G-CIEMS is a spatially resolved and geo-referenced, dynamic, multimedia environmental fate model. This model predicts the concentrations of chemicals in the atmosphere, surface water, surface–water sediments, and surface soil based on environmental emissions and physico-chemical properties of a target substance and on geographical and meteorological information. (Japanese only)
KAshinhou Tool for Ecotoxicity (KATE) (Japanese)

KAshinhou Tool for Ecotoxicity (KATE)

KATE is a web-based software service that can be used to predict ecotoxicity values such as fish acute toxicity (median lethal concentration [LC50]) and daphnia immobilization (median effect concentration [EC50]) by using original quantitative structure-activity relationship models that assess the quantitative relationship between the physico-chemical characteristics of a chemical and its biological activities. (Japanese only)
Health Effects Alert System (HEALS)

Health Effects Alert System (HEALS)

HEALS (Health Effects Alert System) includes four subsystems—ChemToxGen, ChemArrayDB, pCEC, and MulCEH— that can be used to evaluate the effects of environmental chemicals by using a variety of databases and algorithms. This system classifies chemicals that act on cells and tissues from the viewpoint of gene expression signatures, cellular functions, and organ toxicities. Furthermore, a high-performance Bayesian network system, RX-TAOGEN in MulCEH can be used to predict the underlying mechanisms of chemical toxicity by examining gene expression and cellular phenotypes.
Environmental Analytical Method Database (EnvMethod) (Japanese)

Environmental Analytical Method Database (EnvMethod)

EnvMethod is a database containing information on environmental measurement methods that is searchable by chemical name, relevant regulation, reference, analytical method, and/or environmental medium. This database is linked to WebKis-Plus database. (Japanese only)
Simulation Models and Tools for Exposure Assessment (Japanese)

Simulation Models and Tools for Exposure Assessment

This suite of tools contains G-CIEMS, an integrated tool for assessing environmental risk, the Multimedia Simplebox-systems Environmental Model (MuSEM), a tool for visualizing geographic information system data containing simulation results from G-CIEMS, and other tools for assessing exposure to environmental chemicals. (Japanese only)
Aquatic Tri-trophic Ecological Risk Assessment Model (A-TERAM) (Japanese)

Aquatic Tri-trophic Ecological Risk Assessment Model (A-TERAM)

A computational risk assessment system to evaluate the ecological effect of chemicals based on the ecological model in which biological factors such as interspecific interactions are integrated into the basic ecotoxicity data experimentally estimated for the three trophic levels (algae, daphnia, and fish). (Japanese only)
Integrated Exposure Effects Analysis (IEEA)

Integrated Exposure Effects Analysis (IEEA)

This website is set up in order to further cultivate the communication among researchers who work on the IEEA field. This site is also aimed at bringing biologists/toxicologists and analytical chemists, who now work independently, together to further expand the IEEA research. Materials such as workshop proceedings and publications will be posted within the site. Inputs from interested parties will be shared among the group.
