Software Downloads

Two pieces of software, with associated guidance, have been developed as part of the inchemicotox project. Both can be downloaded from this page.

The “Eco-Derek” tool was designed to make semi-quantitative predictions of acute aquatic toxicity (described as very high, high, medium, low or very low) in Tetrahymena pyriformis using an adaptation of the reasoning in Lhasa Limited’s Derek program and an analysis of a published toxicity dataset that had been compiled and checked in an earlier part of the project.  The knowledge base of the program consists of a set of structural alerts linked to approximate rules regarding potency, taking into account supplied (or calculated) versions of the octanol-water partition coefficient. The present release for the project should be considered as a “proof-of-concept” demonstration model.”

The Integrated Testing Strategies (ITS) for alternatives to animal testing developed as part of this project have been compiled in a Windows-based interactive decision tool intended for risk assessors and researchers. The “ITS Adviser” was designed to encourage the uptake of alternative “non-test” methods by giving advice on their application in the context of ITS for acute fish toxicity and skin sensitisation.  It is primarily designed for use in the context of REACH, but may be useful for considering evaluations under other regulations or for company internal hazard/risk assessments.
