POPs bio-magnify throughout the food chain and bio-accumulate in organisms. 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.
Where can we find POPs?
Today, POPs are found almost everywhere – in our food, soil, air and water. Wildlife and humans around the world carry amounts of POPs in their bodies that are at or near levels that can cause injury.

What are POPs quizlet?
Persistent Organic Pollutants. Chemical substances that persist in the environment, bioaccumulate through the food chain, and pose a risk of causing adverse effects to human health and the environment.
What is DDT and its uses?
Dichlorodiphenyltrichloroethane (DDT) is an insecticide used in agriculture. The United States banned the use of DDT in 1972. Some countries outside the United States still use DDT to control of mosquitoes that spread malaria.
Are POPs banned?
Use of internationally banned chemicals Polychlorinated biphenyles (PCBs) and organochlorine pesticides (OCPs) are the most dangerous forms of POPs. DDT is the most commonly known POP and has been banned in the US and Europe since 1972. These chemicals pose high risk of exposure to human health.
Are VOCs a pop?
Persistent Organic Pollutants (POPs) are an integral part of the PBT (Persistent Bio-accumulative Toxic Chemicals), which additionally includes trace metals and organo-metal compounds. Volatile Organic Compounds (VOCs) are hydrocarbons that become volatile (change into gaseous form) at room temperature.
Why do POPs not break down easily in the environment?
POPs generally have low water solubility (they do not dissolve readily in water) and high lipid (fat) solubility (they do dissolve easily in fats and oils). Persistent substances with these properties bioaccumulate in fatty tissues of living organisms.
