What's
Involved in a Toxicologic Evaluation?
Toxicologic evaluations are conducted to find out whether people are
contacting chemicals at levels that can hurt them.
ATSDR has developed the following key steps for conducting a toxicologic
evaluation.
|
Step 1 .
|
For each chemical selected for further evaluation, estimate the
amount of the chemical that would enter a person's body (this is
called the exposure dose). The estimate
is based on how the chemical gets into the body.
|
|
Step 2.
|
Compare the estimated exposure doses to health
guidelines to determine which exposure doses need more evaluation.
|
|
Step 3.
|
Use results of previous studies of humans and animals to judge
the likelihood for health effects to result
from the specific exposures investigated.

Why is knowing about toxicology important for community members?
|
|
|
Do health assessors conduct the toxicologic evaluation themselves?
