KAshinhou Tool for Ecotoxicity (KATE)

KAshinhou Tool for Ecotoxicity (KATE)

Prediction tool of a chemical’s aquatic toxicity to fish, daphnid, and algae

KATE is a web application tool that predicts ecotoxicity values to aquatic organisms (fish, water flea (Daphnia magna) and algae) according to "OECD Test Guidelines for Chemicals." The tool is based on quantitative structure-activity relationship (QSAR) models and predicts both acute and chronic ecotoxicity values.

Compendium of Reference Materials on the Grounds for the Establishment of Environmental Quality Standards

Compendium of Reference Materials on the Grounds for the Establishment of Environmental Quality Standards

What are the bases for establishing environmental quality standards in Japan?

The environmental quality standards (EQSs) for air, water, soil, and noise have been established and revised by the Ministry of the Environment, Government of Japan. This website collects references regarding the establishment and revision of EQSs and related items such as guideline values. The documents, references, and main texts on this website are written in Japanese, but summaries for each environmental medium will be translated into English.

Chemical Substance Database (Webkis-Plus)in Japanese

Chemical Substance Database (Webkis-Plus)

Get comprehensive information on chemical substances by extensive search functions

Webkis-Plus is a website providing comprehensive information relating to environmental risk management. This site contains information on physicochemical properties; regulations (related mainly to environmental pollution); environmental concentrations from surveys; volumes of substances manufactured, imported, or both; volumes of agricultural chemicals shipped to each prefecture; Pollutant Release and Transfer Register (PRTR) emissions and transportation amounts; risk assessment results; and so on. (in Japanese)

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

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

Simulates the environmental fate of contaminants throughout Japan

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 waters, surface water sediments, surface soils, coastal waters, and sewage collection areas based on environmental emissions and physicochemical properties of the target substances and use of geographical and meteorological information. (in Japanese)

Simulation Models and Tools for Exposure Assessmentin Japanese

Simulation Models and Tools for Exposure Assessment

Get models and tools for simulating environmental fates and visualizing geographic data

This website provides the following models and tools: G-CIEMS; the Multimedia Simplebox-systems Environmental Model (MuSEM), which is an integrated tool for assessing environmental risk; and a tool for visualizing geographic data containing simulation results obtained by G-CIEMS, and so on. (in Japanese)

Tools for GC(×GC)-MSin Japanese & English

Tools for GC(×GC)-MS

A collection of programs designed for accurate mass spectrometry data analysis (for researchers)

This page provides original software to analyze data from a gas chromatograph-mass spectrometer (GC-MS) or a comprehensive two-dimensional gas chromatograph (GC×GC)-MS. A GC×GC is an instrument that can separate dozens of times more components than a conventional GC, allowing simultaneous separation of many kinds of chemicals. In addition, the high-resolution time-of-flight mass spectrometer (HRToFMS) is capable of extremely fast, accurate mass analysis. The combination of these instruments contributes to research on environmental pollution caused by a wide and complex variety of chemicals. (in Japanese & English)

Tsukuba Air Quality Monitoring Datain Japanese

Tsukuba Air Quality Monitoring Data

Real-time PM2.5 and other air quality concentrations are reported.

As a part of quality control of the measurements, continuous air quality monitoring has been conducted at the Atmospheric Measurement and Experiment Laboratory (Air Quality Research Station) of NIES since 1978. The measurement results since 1995 are available on our website, and more detailed information and data can be provided upon request. (in Japanese)



Environmental Certified Reference Materials (CRMs) are utilized to evaluate new analytical methods and to control the accuracy of pretreatment and instrumental analyses.
National Institute for Environmental Studies (NIES) have been preparing and distributing environmental and biological CRMs since 1980.
At present, 17 CRMs are available (including 1 CRM which cannot be sent overseas).
