PBT Compounds

PBT compounds are chemicals that are persistent, bioaccumulative, and toxic. They degrade very slowly in the environment, accumulate in living organisms, and can have harmful effects on health and ecosystems. Common examples include PCBs, DDT, mercury, and dioxins. Due to their environmental and health risks, PBT compounds are heavily regulated under international agreements like the Stockholm Convention on Persistent Organic Pollutants. Efforts are focused on reducing their use and cleaning up contaminated sites to protect ecosystems and human health.
