explain why risk assessors use a reference dose to quantify noncarcinogenic toxicity but use a cancer slope factor to qualify carcinogenic toxicity
1. explain why risk assessors use a reference dose to quantify noncarcinogenic toxicity but use a cancer slope factor to qualify carcinogenic toxicity
2. identify characteristics that influence perceptions of the acceptability of an environmental health risk
3. provide examples of environmental laws or approaches that demonstrate the risk protection principles of environmental justice, precautionary principle, polluter pays, and sustainability.
Modern toxicology is no longer anthropocentric but rather takes a holistic approach to many biological systems, such as ecosystems. When exposed to specific chemical substances, such as medications, they will interact in a unique way. Negative interactions between the substance and the exposed biological system cause adverse effects during pharmacological therapy or after (accidental) poisoning. Toxicity is no longer a property of medications and chemicals, but rather a phrase used to characterize the negative consequences of a drug-host interaction.
