All POP emissions decreased substantially between 1990 and 2019: Dioxins (Teq) by 85%, PCB by 88%, HCB by 99.6% and PAH Total by 49%. But uncertainties are significantly higher than for the other air pollutants reported. | + | Persistent organic pollutants give a mixed picture both in terms of development and sources.
