what are the positive effects of chemistry on public health???????

Answer 1

Toxicology and Epidemiology are both based in chemistry. They have to do with outside chemicals and their effect on the health of the public.

Think about this: you have a gas leak from a plant. An official from public health has to determine how that gas will affect people and their health, which way the gas might blow, its effect on the environment, and the safest course of action to keep people safe and healthy.
