Final answer:
Toxicological information is true in providing ways to prevent health effects due to chemical exposure, essential within the domain of environmental toxicology that includes dose-response studies and measures to protect from environmental toxins.
Step-by-step explanation:
Toxicological information is crucial as it provides guidance on how one can prevent adverse health effects upon exposure to chemicals, thereby indicating that the statement is true. This information comes from the study of environmental toxicology, which involves understanding the dose-response relationship and the management of the environmental toxins to protect both humans and the environment.
For instance, if an environmental toxicologist discovers that a chemical causes birth defects, it highlights the chemical's toxicity and harmful effects on human health. Such information would underscore the importance of preventing exposure or at least minimizing it to mitigate these effects. Similarly, understanding the toxic components present in substances like tobacco smoke is vital for public health. Toxic chemicals like nicotine, which is highly addictive, more so than heroin, can be identified and their risks communicated to the public.
Environmental Biology often stresses the precautionary principle, which advocates for caution in the usage of new chemicals whose health and environmental effects may not be wholly established. Additionally, protective measures like feedback inhibition are biological processes that prevent cellular toxicity, demonstrating another layer of defense against harmful substances.
