What is the significance of toxicological findings?
As such, toxicological analysis represents a tool for assessing the degree of impairment exerted by a drug or combination of drugs. With the ultimate degree of impairment being death, toxicological findings are also used to determine cause and manner of death.

Why is toxicology important to the environmental health field?
Toxicology is a field of science that helps us understand the harmful effects that chemicals, substances, or situations, can have on people, animals, and the environment. Toxicology uses the power of science to predict what, and how chemicals may cause harm and then shares that information to protect public health.
