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).

Workshop reviews advances in Environmental Exposure Modelling: Bridging the Gap between Research and Application

In a nutshell:

Advances in Environmental Exposure Modelling:
Bridging the Gap between Research and Application.

ECETOC Workshop held 4-5 May 2017, Brussels

 

Brussels, March 2018.

This workshop was held to assess the current status of the science of environmental chemical exposure modelling in order to identify areas for improvement and recommend practical steps to improve the current situation. The workshop was attended by sixty international scientific experts from industry, academia, regulatory agencies and consultancies.

Assessing environmental exposure of chemicals is a challenging but critical part of assessing environmental risk. While there has been a great deal of resource directed towards activities aimed at advancing the use and application of exposure models, this ECETOC workshop provided the opportunity to review the recent advances in exposure models, with a particular focus on the following key themes:

  • Quantification of uncertainties
  • Identification of synergies across the different industry sectors and regulatory bodies
  • Applicability domain challenges
  • Chemical mixtures
  • Non-chemical stressors

Both regulatory and research-oriented models were considered within focused syndicate sessions dedicated to various categories of industrial chemicals.

The workshop included an IT Modelling Fair at the end of the first day, where some of the participants demonstrated exposure modelling tools and offered attendees some hands-on experience.

Workshop participants agreed on a number of general principles of best practice in environmental exposure modelling, and some recommendations were identified for practical steps towards improving the use and application of models. These are captured in the workshop report.

This report will be of interest to academic researchers, industrial environmental fate assessors, and regulatory bodies involved in chemical risk assessment.
