Description:
The goal of alternatives assessment is to identify safer alternatives for chemicals of concern. Comparative chemical hazard assessment is an important component of alternatives assessment. The Hazard Comparison Dashboard (HCD) displays compiled chemical hazard data in a condensed format to enable users to readily compare alternatives. Hazard is evaluated by assigning a color-coded score (Low, Medium, High, or Very High) for each of twenty different categories including acute toxicity, carcinogenicity, and exposure. Chemical hazard data was obtained from public online sources including chemical hazard lists, Globally Harmonized System (GHS) scores, and databases of quantitative toxicity values (e.g. ToxValDB). Predicted values are also generated using QSAR models (e.g. EPA’s Toxicity Estimation Software Tool, T.E.S.T). The scoring criteria were based on the EPA’s Design for the Environment Program (DfE) Alternatives Assessment Criteria for Hazard Evaluation. HCD can also display the scoring profile for environmental breakdown products and chemical analogs for the chemicals being evaluated. HCD is available as a web application and a downloadable Java application.
