Overview


Persistent bioaccumulative toxicants (PBTs), also known as persistent environmental contaminants, persistent pollutants, or persistent toxic chemicals, are resistant to environmental degradation through chemical, biological, and photolytic processes. They have been observed to persist in the environment, be capable of long-range transport, bioaccumulate in human and animal tissue, biomagnify in food chains, and have potential significant impacts on human health and the environment.
