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.
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.
TRA Task Force – Worker branch

TRA Task Force – Worker branch

Why? The Worker TRA Task Force has been active since 2019, delivering projects that advance the scientific basis of the Worker Targeted Risk Assessment (TRA) tool. Its overarching objective is to e...
