What are considered persistent organic pollutants?
Persistent Organic Pollutants (POPs) are toxic substances composed of organic (carbon-based) chemical compounds and mixtures. They include industrial chemicals like PCBs and pesticides like DDT. They are primarily products and by-products from industrial processes, chemical manufacturing and resulting wastes.
Which of the following is an example of a persistent organic pollutant?
Persistent organic pollutants are also toxic to living organisms. Examples of POPs include DDT, polychlorinated biphenyls (PCBs) and some per- and polyfluoroalkyl substances (PFAS).
What is the main aim of Stockholm Convention on Persistent Organic Pollutants?
The Stockholm Convention is a global treaty that aims to protect human health and the environment from the effects of persistent organic pollutants (POPs). The Convention entered into force on May 17, 2004.
Is TBT a persistent organic pollutant?
TBT compounds have been detected in a number of environmental samples. As for other persistent organic pollutants, dietary intake is most probably the main route of exposure to TBT compounds for the general population. However, data concerning TBT levels in foodstuffs are scarce.
What are persistent organic pollutants used for?
The Stockholm Convention on Persistent Organic Pollutants, which was adopted in 2001 and entered into force in 2004, is a global treaty whose purpose is to safeguard human health and the environment from highly harmful chemicals that persist in the environment and affect the well-being of humans as well as wildlife.
What are persistent organic pollutants give 5 examples?

Where can you find persistent organic pollutants?
The highest concentrations of POPs are thus found in organisms at the top of the food chain. Consequently, background levels of POPs can be found in the human body.
What happened at the Stockholm Convention?

Are organophosphates Persistent Organic Pollutants?
Evaluation of evidence that the organophosphorus insecticide chlorpyrifos is a potential persistent organic pollutant (POP) or persistent, bioaccumulative, and toxic (PBT)
Why is TBT banned?
Bottom paint improves ship performance and durability as it reduces the rate of biofouling (the growth of organisms on the ship’s hull). The TBT slowly leaches out into the marine environment where it is highly toxic toward nontarget organisms. After it led to collapse of local populations of organisms, TBT was banned.
