Risk Assessment Tools

Tools to Support Chemical Risk Assessment


Based on the models proposed by the International Commission on Radiological Protection (ICRP), the Simple Code for Aerosols via the Respiratory Route to Estimate Deposition in the Lung (SCARRED Lung) has been developed in ‘Microsoft Visual Basic .NET’. By using the calculation code, the deposition and clearance patterns of aerosols can be easily evaluated. The detailed theoretical description, which was reported in the ICRP Publications 66 and 71.

Risk Learning(In Japanese only)

An educational tool to estimate human health risks of a specific chemical substance in environmental media (air, water, soil, etc.) or contact media (food, etc.) using carcinogenic risk and hazard quotient as risk indices. Using Risk Learning it is possible to determine the exposure route that contributes most to human health risk of a certain chemical substance.

Video for the Fragmented Testis Method: A New Quantitative Evaluation Technique for
Detection of Testis-Ova in Male Fish Using the Medaka (Oryzias latipes) (In Japanese only)

This video shows a new quantitative evaluation technique, termed the fragmented testis method,
developed by CRM/AIST for the detection of testis-ova in genotypic male fish
using the medaka (Oryzias latipes). 

The routine traditional histological method for detection of testis-ova in male fish exposed to estrogens
or suspected endocrine-disrupting chemicals has several disadvantages, including possible oversight of testis-ova due to limited observation of selected tissue sections. 

The method we have developed here allows for the accurate determination of the developmental stages,
the number and the size of testis-ova in a whole testis. 

This method proved to be a convenient and cost-effective method for quantitatively evaluating testis-ova appearance in fish,
and is expected to contribute to the clarification of the mechanism of testis-ova appearance and its biological significance in future studies of endocrine disruption.
