AOPLink: two major research questions
Q1: For an AOP, which experimental data is available to support the AOP?
Q2: Can this experimental data support an existing AOP?

AOPs can play major role in risk assessment
Aid Integrated Approaches to Testing and Assessment
Predictive value
Less need for animal testing
Identify knowledge gaps
