Chapter 3 (Continued)

Antagonistic

- Chemicals inhibit each others actions.

- Integrates Information from hazard identification, dose response relationship, and exposure assessment.

Dose Response Assessment

- Measuring The amount of exposure and the subsequent response.

Risk Management

- Is done after the risk assessment and is actions taken to control exposure and reduce or avoid the risk.
