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.

WHO launches new Chemical Risk Assessment Network

Chemicals play a vital part in our daily life. Chemicals can also cause unintended harm to human health. More than 25% of the global burden of disease is linked to environmental factors, including chemicals exposures. The production and use of chemicals continues to increase worldwide, particularly in rapidly developing economies.

Enhanced global efforts are needed to share expertise, to assess, and to manage the risks associated with exposure to hazardous chemicals. There is a need to identify knowledge gaps and emerging issues, and to provide a forum for scientific exchange and collaboration on risk assessment.

To support these efforts, WHO has today announced the launch of a network of leading risk assessment institutions from around the world, to improve chemical risk assessment globally. The network will scale up action and facilitate sustainable interaction between institutions on chemical risk assessment. The network is a voluntary, collaborative initiative.

Network objectives

  • Provide a forum for scientific and technical exchange;
  • Facilitate and contribute to capacity building;
  • Promote best practices and the harmonization of methodologies;
  • Assist in the identification of research needs and promote the application of new science in risk assessment practice;
  • Assist in the identification of emerging risks to human health from chemicals;
  • Share information about work programmes to avoid duplication of effort; and
  • Upon request, assist WHO in the development of training and other materials in support of the above.

Invitation to become a network participant

Institutions engaged in human health risk assessment of chemicals are invited to become network participants. For more information about the Network and how to become a network participant, consult or download the following documents:
