A research team is studying the effects of a newly discovered industrial chemical on human health. They conduct a study where they expose laboratory animals to varying doses of the chemical and observe the following: At low doses, there are no observable effects; at moderate doses, there are some reversible physiological changes; and at high doses, there is significant organ damage. Critically evaluate how this information should be used in the establishment of safety standards for human exposure to this chemical.
