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

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...

Case Studies on Reliability and Relevance Considerations during Validation of NAMs

Why?Validation of NAMs is often overlooked despite its importance for regulatory use. Traditional validation methods are less suitable for NAMs, which focus on key events rather than apical...

Assessing the human health and environmental safety of polymers

Why?

Polymers pose technical/scientific challenges for risk assessment.​ Polymers are versatile and complex, and generally not present as mono-constituent substances, but as complex polymer products consisting of the polymeric substance (polymeric macromolecules), intentionally added substances (IAS; e.g.stabilisers) and non-intentionally added substances (NIAS; e.g. impurities).

Conventional risk assessment approaches may not apply to the majority of polymers.

Objectives

  • Considering existing risk assessment approaches (e.g. food safety regulation, EU Technical Guidance Document/REACH Guidance, international polymer assessment frameworks), develop a conceptual framework for human health and environmental safety assessment of polymers
  • Liaise with stakeholders and contribute to relevant initiatives.

Timeline and Deliverables

Work started in September 2023 and the Task Force published the following Technical Reports from 2019 – 2021 ((complete reports are available for download from the column on the right)):

  • TR 133-1 in May 2019 (Conceptual Framework for Polymer Risk Assessment (CF4Polymers))
  • TR 133-2 in March 2020 (Applicability of analytical tools, test methods and models)
  • TR 133-3 in September 2021 (Case-studies putting the CF4Polymers into practice)​

The Task Force actively contributed during 2020 - 2022 to the CARACAL subgroup (CASG) on Polymers.

A manuscript on a Three-tiered approach for standard information requirements for polymers requiring registration under REACH (Otte JC and Hollnagel HM et al., 2023) was published in October 2023.
