| pollution sink (Vehicle for removal of a chemical or gas from the atmosphere-biosphere-ocean system, in which the substance is absorbed into a permanent or semi-permanent repository, or else transformed into another substance. A carbon sink, for example, might be the ocean (which absorbs and holds carbon from other parts of carbon cycle) or photosynthesis (which converts atmospheric carbon into plant material). Sinks are a fundamental factor in the ongoing balance which determines the concentration of every greenhouse gas in the atmosphere. If the sink is greater than the sources of a gas, its concentration in the atmosphere will decrease; if the source is greater than the sink, the concentration will increase) |

| polybrominated biphenyl (A chemical substance the composition of which, without regard to impurities, consists of brominated biphenyl molecules) |

|
| polychlordibenzo-p-dioxin (PCDD are formed (along with variants including furans) when compounds containing chlorine are burnt at low temperature in improperly operated/designed domestic refuse and industrial waste incinerators where PCDDs can be found in both the flue gases and the fly ash) |

| polychlorinated biphenyl (PCBs are a family of chemical compounds which do not exist in nature but which are man-made. Commercial mixtures are clear, pale yellow liquids, manufactured by the replacement of hydrogen atoms on the biphenyl molecule by chlorine. Because of their physical properties, PCBs are commonly found in electrical equipment which requires dielectric fluid such as power transformers and capacitors, as well as in hydraulic machinery, vacuum pumps, compressors and heat-exchanger fluids. Other uses include: lubricants, fluorescent light ballasts, paints, glues, waxes, carbonless copy paper, inks including newspapers, dust-control agents for dirt roads, solvents for spreading insecticides, cutting oils. PCBs are stable compounds and although they are no longer manufactured they are extremely persistent and remain in huge quantities in the atmosphere and in landfill sites. They are not water-soluble and float on the surface of water where they are eaten by aquatic animals and so enterthe food chain. PCBs are fat-soluble, and are therefore easy to take into the system, but difficult to excrete) |

| polychlorinated dibenzofuran (A family containing 135 individual, colorless compounds known as congeners with varying harmful health and environmental effects. They are produced as unwanted compounds during the manufacture of several chemicals and consumer products such as wood treatment chemicals, some metals, and paper products; also produced from the burning of municipal and industrial waste in incinerators, from exhaust of leaded gasoline, heat, or production of electricity. They are hazardous to the respiratory system, gastrointestinal system, liver, musculoskeletal system, skin and nervous system; and are toxic by inhalation, ingestion, and contact. Symptoms of exposure include frequent coughing, severe respiratory infections, chronic bronchitis, abdominal pain, muscle pain, acne rashes, skin color changes, unexpected weight loss, nonmalignant or malignant liver disease) |
