What is the significance of the "dose-response" relationship in toxicology?

It describes how the severity of the response (effect) is related to the dose (amount) of the chemical.

What is an "acute" health effect?

An effect that manifests rapidly after exposure.

What is a "chronic" health effect?

An effect that appears after a long period of exposure or repeated exposures.
