Computational & Informatics Approaches

NICEATM explores how mathematics, informatics, and computer models can be used to understand toxicity mechanisms and predict toxic effects. Details of these projects and tools are described below.

In May 2024, NICEATM presented a training session on tools and data resources available in the Integrated Chemical Environment (ICE). View slides from the training.

Descriptions

Integrated Approaches to Testing & Assessment (IATAs)

IATAs enable all available information about a substance to inform a decision about the risk it may pose. Learn more about IATAs. Go

OPERA

The Open (Quantitative) Structure-activity/property Relationship App (OPERA) provides predictions on physicochemical properties, environmental fate, and toxicity endpoints. Learn more about OPERA. Go
