From 24 April 2024 there will be changes to categorisation, reporting & record keeping requirements - see announcements on changes to the General Rules & changes to the Categorisation Guidelines.

Appendix - In silico predictions for categorisation

Use information on this page to help you complete steps 4.4 and 5.4 to work out the human health hazard characteristics and environment hazard characteristics of your introduction. 

These tables are an overview on which human health and environment hazard characteristics have in silico options, and which in silico options are appropriate.

In silico models for human health hazard characteristics
