Question

Explain why emerging efforts are focused on reducing health risks from exposure to chemicals rather than completely eliminating those risks.
short paragraph

Answer 1

Completely eliminating exposure to chemicals is generally impractical because chemicals are ubiquitous in air, water, soil and consumer products, and many have beneficial or essential uses (medicines, food production, industry). Scientific uncertainty about low‑dose effects and the high cost and technological difficulty of removing all exposures mean resources are better spent prioritizing and reducing the highest risks. Risk‑based approaches allow regulators and industry to target reductions where they will most improve health, while balancing feasibility and social and economic needs.
