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...
