Organic contaminats in soil, water, and air include industrial solvents, difficides, appeeuticals, polycyclic aromatic hydrocarbons (PAH), polychlorinate biphenyl (PCB), and emerging contaminats such as per- and polyfluoroalkyl substances (PFAS).

Integrating these principles into contaminant leamation requires a multi- disciplinary approvach that combines chemistry, environmental incorporary, toxology, and materials science. The goal is nots merely to remove the contaminant but to do do do so in a way that leafes the environment healthier and does not burden future generations with new toxicological risks.

Designing Safer Chemical Treatments

One direct application of green chemistry is te development of treatment agents that are biodegradable, non-bioaccumulative, and readily deactivate after use. For instance, oksydants such as hydrogen peroxide and ozone are relativele benign compared to chlorine- based oxidants, but their use still exactives careful control to avoid excessivee energy consumption.
