HESI Risk Assessment in the 21st Century (RISK21) Project

About RISK21®

Mission

Harmonize the approach to how the world evaluates chemicals using a risk-based approach.

Principles of RISK21®

  • Problem-formulation based
  • Risk-based at each step of the process
  • Use of prior knowledge
  • Fit for purpose
  • Value of information
  • “Enough precision to make the decision”
  • Provide a framework that is flexible, transparent, visual

Impact

  • Actively involved 120 stakeholders during development from 2010 – 2017
  • Has held >20 hands-on case study workshops in 15 countries with regionally-tailored case studies
  • Cited and applied in numerous publications and reports across diverse chemistries and contexts

Version 2.0 of the RISK21® Webtool is Now Available!

21st Century Framework

The webtool supports a problem formulation-based, exposure-driven, tiered acquisition approach that leads to an informed decision.

Transparent and Consistent

The webtool approach allows users to  optimize the use of resources and information available for chemical risk assessment.

Create Custom Plots

Users can interact with the RISK21 webtool application to visualize their own risk data, creating a custom plot which will be displayed on the screen.

RISK21® Roadmap and Matrix

The RISK21 webtool application allows users to input estimated exposure and toxicity data for each chemical, and will plot the intersection area, overlaying a risk matrix represented as a heat map.
