Environmental Pollution: Persistent Organic Pollutants (POPs)
Features Persistence: POPs resist degradation in the environment, remaining active for years or even decades. Bioaccumulation: They accumulate in the fatty tissues of living organisms, increasing in concentration as they move up the food chain. This process, known as biomagnification, … Continue reading
