any one of many synthetic compounds including polychlorinated byphenyls (PCBs), polychorinated dioxins and furans, pesticides such as DDT, chlordane, and heptachlor. They persist in the environment and accumulate through the food chain or in the sediment to a toxic level that is directly harmful to aquatic organisms and humans
Chemicals that endure in the environment and bioaccumulate as they move up trough the food chain. They include organochlorine pesticides, polychlorinated biphenyls (PCBs), dioxins, and furans.
Chemical substances which can have adverse effects and remain in the environment for many years in an unchanged form.
class of chemicals that persist in the environment, are capable of long-range transport, bioaccumulate in human and animal tissue, and have significant impacts on human health and the environment
Also known as persistent toxic substances, POPs are chemical substances that persist in the environment, bioaccumulate through the food web, and pose a risk of causing adverse effects to human health and the environment. Some examples of POPs include DDT, PCBs and mercury.
Persistent Organic Pollutants (POPs) are chemicals, chiefly compounds of carbon, that persist in the environment, bioaccumulate through the food chain, and pose a risk of causing adverse effects to human health and the environment. more
Persistent organic pollutants (POPs) are a group of human-made chemicals used as pesticides and as industrial chemicals. POPs can be transported long distances in the atmosphere and can stay in the environment for many years.
Pollutants that remain in the environment for a long period of time, are stored in fat, and are toxic. Examples of POP's include: dioxins, PCB's, lead, arsenic, cadmium, mercury, and chlorinated pesticides.
POPs are chemicals that remain intact in the environment for long periods, become widely distributed geographically, accumulate in the fatty tissue of living organisms and are toxic to humans and wildlife.
Organic substances that do not break down quickly in the environment and are readily taken in by living organisms through contaminated food or polluted water or air. These pollutants include some pesticides (e.g., DDT, Chlordane, Endrin); industrial chemicals (e.g., PCBs) or byproducts; and contaminants (e.g., dioxins and furans).
