HSSD Tool

HSSD Tool

This software was developed by a consortium of partners to facilitate the uptake of novel approaches to estimate aquatic threshold concentrations (e.g. the concentration at which 5% of the species are exposed above their EC50, HC5).
The Human Exposure Assessment Tools Database (heatDB)

The Human Exposure Assessment Tools Database (heatDB)

heatdb is a public directory of exposure data sources as well as available tools for exposure
NanoApp

NanoApp

ECETOC’s NanoApp is a tool designed to define the boundaries of sets of similar nanoforms and to generate a justification for the REACH registration.
Targeted Risk Assessment (TRA)

Targeted Risk Assessment (TRA)

The Targeted Risk Assessment (TRA) estimates exposures to workers, consumers and the environment that arise during a series of events.
Chronic fish case studies towards an IATA

Chronic fish case studies towards an IATA

Why?Hazard and safety assessments for the pelagic compartment often rely on in vivo studies using a single fish species, raising ethical concerns and uncertainty in terms of extrapolation....

EPAA and NC3Rs final call for data: acute oral toxicity studies

ECETOC is supporting this call for data for acute oral toxicity studies. In collaboration with the European Partnership for Alternative Approaches to Animal Testing (EPAA), the National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) request access to study reports for acute oral toxicity studies, in order to develop a database of clinical signs observed during these studies.

The data will be analysed and used to develop more objective guidance on the use of ‘evident toxicity’ as an endpoint within the Fixed Dose Procedure (FDP, OECD Test Guideline 420) to support wider use of this test guideline. This test uses fewer animals than other accepted methods and does not use death as an endpoint, giving clear animal welfare benefits.

A significant number of studies have already been collected, but there is still time to contribute to this project!  Data contributors will be invited to participate in discussions on the analysis and resulting recommendations.

Please contact Fiona Sewell (fiona.sewell@nc3rs.org.uk) by 31 August 2020 for more information.
