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.

Scientific concepts and methods for moving persistence assessments into the 21st Century

In a nutshell

A Task Force from the Centre for chemical safety assessment (ECETOC) has carried out a study into improving methods to evaluate a chemical’s persistence in the environment and its subsequent risk to the plant and animal life of a region. The findings are published in the peer-reviewed journal Integrated Environmental Assessment and Management (IEAM).

Chemical persistence in the environment is one of the most important criteria in the regulation of organic chemicals. The Task Force reviewed both the challenges and the limitations of current testing methods, as well as the scientific advances that can help provide additional understanding and new solutions.

A first paper on the subject written by the same Task Force and published on the same journal can be accessed here.
