January 2026 news from the Sec Gen

Dear colleagues and friends,As we begin a new year, I would like to thank you for your continued engagement and trust in ECETOC. 2026 promises to be an exciting and dynamic year, and I am pleased...
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....
Estimating the environmental release of Synthetic Polymeric Microparticles from Products

Estimating the environmental release of Synthetic Polymeric Microparticles from Products

Why?REACH restriction: SPM use restricted; emissions reporting required by May 2027. Gap: No analytical methods available to measure SPM emissions. Solution: Draft SPERC-based approac...
Case Studies on Reliability and Relevance Considerations during Validation of NAMs

Case Studies on Reliability and Relevance Considerations during Validation of NAMs

Why?Validation of NAMs is often overlooked despite its importance for regulatory use. Traditional validation methods are less suitable for NAMs, which focus on key events rather than apical...

Special Report no.19: Building a Prenatal Developmental Toxicity Ontology

This report discusses the need for a systematic representation of knowledge about developmental toxicity (i.e. an ontology) that would enable computer-based prediction of which chemicals are likely to...

Workshop Report no.29 – Defining the role of chemical activity in environmental risk assessment within the context of mode of action: Practical guidance and advice

Chemical activity has recently been promoted as a useful concept for interpreting and classifying ecotoxicological data and for performing environmental risk assessment of chemicals.  The most common...

Task Forces

Staged assessment: Exemplify the staged assessment process by using it to provide more information in low tonnage bands

Staged assessment: Exemplify the staged assessment process by using it to provide more information in low tonnage bands

Why? The current paradigm for identifying data (study) requirements is based upon a surrogate of exposure, namely production volume, which may under or overestimate real exposure. As presented in ...
Smart studies: Examine how in vivo studies could provide more information encompassing novel studies (and endpoints)

Smart studies: Examine how in vivo studies could provide more information encompassing novel studies (and endpoints)

Why? “Smart” or extended studies can be defined as in vivo studies that employ additional or different endpoints from conventional studies.They fall into 2 categories:those that follo...
Use of clinical data in identification of respiratory sensitisers

Use of clinical data in identification of respiratory sensitisers

Background There has been a propensity by regulators to rely primarily on health surveillance/clinical case study data (case reports, clinical databases, worker exposure studies) to classify substa...
Dose Selection Task Force

Dose Selection Task Force

Background Recent opinions published by the RAC on low top dose selection in animal toxicity studies have indicated an apparent intent of increasing dosages systematically in view of the criteria u...
