Persistent, Bioaccumulative, and Toxic (PBT) substances
Persistent, Bioaccumulative, and Toxic (PBT) substances are chemicals that remain in the environment for a long time (persistent), build up in the tissues of living organisms (bioaccumulative), and can cause harm, such as health problems or environmental damage (toxic). They are especially concerning because they don’t break down easily, accumulate through the food chain, and pose risks to both ecosystems and human health. Managing PBT substances is important to prevent long-lasting contamination and protect living beings from harmful effects.
