WitrynaOrganic pollutants, which are a group of extremely toxic synthetic organic compounds, have a prolonged endurance under natural conditions in the environment. To assess human exposure and health risk, the existence of such organic compounds in humans has turned into a subject of major research (Covaci et al., 2008 ). Persistent organic pollutants (POPs) are organic compounds that are resistant to degradation through chemical, biological, and photolytic processes. They are toxic chemicals that adversely affect human health and the environment around the world. Because they can be transported by wind and water, most … Zobacz więcej POPs typically are halogenated organic compounds (see lists below) and as such exhibit high lipid solubility. For this reason, they bioaccumulate in fatty tissues. Halogenated compounds also exhibit great stability reflecting … Zobacz więcej POP exposure may cause developmental defects, chronic illnesses, and death. Some are carcinogens per IARC, possibly including breast cancer. Many POPs are capable of endocrine disruption within the reproductive system, the central nervous system, … Zobacz więcej Current studies aimed at minimizing POPs in the environment are investigating their behavior in photocatalytic oxidation reactions. … Zobacz więcej The Stockholm Convention was adopted and put into practice by the United Nations Environment Programme (UNEP) on May 22, 2001. The … Zobacz więcej Traditionally it was thought that human exposure to POPs occurred primarily through food, however indoor pollution patterns that characterize certain POPs have … Zobacz więcej Per- and polyfluoroalkyl substances (PFAS) are a class of about 9,000 synthetic organofluorine compounds that have multiple highly toxic fluorine atoms attached to an Zobacz więcej • Air pollution • Aarhus Protocol on Persistent Organic Pollutants • Center for International Environmental Law (CIEL) • International POPs Elimination Network (IPEN) Zobacz więcej

Persistent pollutants: definition, effects and EU regulation News ...
WitrynaThe Stockholm Convention on Persistent Organic Pollutants is a multilateral treaty to protect human health and the environment from chemicals, known as POPs. POPs have harmful impacts on human health or on the environment. They remain intact in the environment for long periods, become widely distributed geographically and … Witryna15 wrz 2015 · These chemical pollutants are referred to as persistent organic pollutants (POPs) (Ashraf et al. 2015 ). POPs have long half-lives in soils, sediments, air and biota. No consensus exists on how long the half-life in a given medium should be for the word “persistent” to be applicable; nevertheless, the half-life of a POP might be … http://chm.pops.int/TheConvention/ThePOPs/The12InitialPOPs/tabid/296/Default.aspx inked subscription
