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.
A chemical will only cause harm after a certain amount of the chemical has been absorbed into a person's body. Toxicologists often say, "it's the dose that makes the poison." Learning about toxicology can help community members better understand health risks and therefore enable them to make better decisions to protect their health and quality of life.
Do health assessors conduct the toxicologic evaluation themselves?
Depending on the specific toxicologic issues at a site, health assessors can conduct toxicologic evaluations themselves or call upon ATSDR toxicologists for assistance. These toxicologists have extensive training and experience in interpreting toxicity information. Senior scientists review the results of all evaluations.
