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....
