Environmental Laboratories Detect, identify, & monitor contaminants
in people and the environment.

The Old Way of Estimating Exposure

An Improved Way
Instead of estimating,
measure levels of chemicals in people.

Take-Away Messages
• Biomonitoring answers constituent questions about whether or not they have been exposed to potentially harmful chemicals.
• Often the answer is that they have not.
• Governmental labs can & should provide these answers.
• By doing so we can calm fears & better target limited resources.
