September 2026 news from the Sec Gen

Dear members and colleagues,As we move through the year, there is a good deal to share. This has been a busy period for ECETOC, with changes to our team, our governance, and the work ahead. Let me...
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.

ECETOC guide to Building a Prenatal Developmental Toxicity Ontology

Brussels, August 2016

This ontology, published as ECETOC Special Report no.19: Building a Prenatal Developmental Toxicity Ontology, provides a way for data and information on developmental toxicology from different sources to be structured and shared in an understandable way. By using a common vocabulary and a user friendly structure, it is envisioned that this particular ontology will allow scientists to make connections and understand relationships between common pathways resulting in adverse reproductive health outcomes.

Such a tool will help scientists and toxicologists predict the possibility of a substance producing developmental toxicity without the need for comprehensive animal testing. It is intended that this ontology can support work currently ongoing at the OECD to reduce reliance on animal testing by moving to a better understanding of the modes of action and biological pathways causing toxic effects.

A paper is also in preparation to be published in the Open Scientific Literature.
