Step 2.3 Evaluating Exposures for Possible Health Effects

bullet Focus of Literature Review

Health assessors look for the following when researching chemical information:

*

The no-observed-adverse-effects-level (NOAEL)

*

The lowest-observed-adverse-effects-level (LOAEL)

*

The mechanisms of toxic actions

*

The strengths and weaknesses of the studies

Epidemiologic studies that are reviewed should be studies similar to those at the site under evaluation in regards to

*

Exposed population

*

Exposure conditions

*

Chemicals
