Persistent organic pollutants, on the other hand, are chemical compounds that, when disposed of, remain in the ground for years or even centuries. POPs with lower molecular weight are less toxic, less persistent in the environment, and have more reversible effects than those with higher molecular masses. What is the importance of Persistent organic pollutants (POPs) with informations from the CDC Statistics Some POPs are toxic ; others are non. The Stockholm Convention on Persistent Organic Pollutants is a global treaty to protect human health and the environment from chemicals that remain intact in the … Persistent Organic Pollutants, or POP's, are synthetic chemicals that are found everywhere and in everything in some form, and cannot be broken down quickly. Introduction.
The more relentless a toxic chemical is, the greater the chance for human exposure over clip. Not only this, but a persistent organic pollutant will pose a hazard to animal, plant and even human life nearby. The harmful effects of these chemicals have been evident since as early as the 1950's, when scientists began to notice strange occurrences happening around the world..
they are hydrophobic and lipophilic, semi-volatility and high molecular masses. Overview. SUMMARY Introduction: Persistent Organic Pollutants (POPs) are a class of chemical compounds that are derived from a particular series or families of chemicals. The Convention entered into force on 17 May 2004. View Persistent Organic Pollutants Research Papers on Academia.edu for free. Persistent organic pollutants (POPs) are chemical compounds that have drawn considerable international attention over the past several decades. Persistent Organic Pollutants have low water solubility i.e. These chemicals possess a combination of physical and chemical properties that allow them to travel long distances, resist degradation, and bioaccumulate. The Stockholm Convention on Persistent Organic Pollutants was adopted by the Conference of Plenipotentiaries on 22 May 2001 in Stockholm, Sweden. Toxic POPs are of particular concern because they frequently remain toxic for decennaries or longer. POPs have a very long life and they persist in the environment for a long time in soils, sediments, air or biota. Persistent organic pollutants (POPs) are considered as the silent killers due to their bio-accumulative and long persistent natures.
