Temporal trends of Persistent Organic Pollutants (POPs) measured in Arctic air are essential understanding long-range transport to remote regions and evaluate the effectiveness national international chemical control initiatives, such as Stockholm Convention (SC) on POPs. Long-term monitoring POPs is conducted under Monitoring Assessment Programme (AMAP) at four stations: Alert, Canada; Stórhöfði, Iceland; Zeppelin, Svalbard; Pallas, Finland, since 1990s using high volume samplers. observed...
The effusive six months long 2014-2015 Bárðarbunga eruption (31 August-27 February) was the largest in Iceland for more than 200 years, producing 1.6 ± 0.3 km 3 of lava.The total SO 2 emission 11 5 Mt, amount emitted from Europe 2011.The ground level concentration exceeded 350 µg m -3 hourly average health limit over much days to weeks.Anomalously high concentrations were also measured at several locations September.The lowest pH fresh snowmelt site 3.3, and 3.2 precipitation 105 away...
The long-term time trends of atmospheric pollutants at eight Arctic monitoring stations are reported. work was conducted under the Monitoring and Assessment Programme (AMAP) Council. were: Alert, Canada; Zeppelin, Svalbard; Stórhöfði, Iceland; Pallas, Finland; Andøya, Norway; Villum Research Station, Greenland; Tiksi Amderma, Russia. Persistent organic (POPs) such as α- γ-hexachlorocyclohexane (HCH), polychlorinated biphenyls (PCBs), α-endosulfan, chlordane, dichlorodiphenyltrichloroethane...
Abstract The Holuhraun eruption in 2014–2015 was the largest Iceland for more than 200 years. It resulted emissions of large quantities volcanic gases into atmosphere (11 megaton (Mt) SO 2 , 0.1 Mt HCl, and 0.05 HF). During had major effects on F, 4 to a lesser extent Cl concentrations precipitaxtion throughout Iceland, not observed recent decades. Cl, ( n = 705) reached values 444 µm 12,270 µm, 17,324 during were average ~20 times higher F much lower compared preeruption times. cations (Si,...
Samples of precipitation have been collected and analysed from four sampling stations in southern Iceland. Sea-salt the has same elemental ratios as seawater its concentration decreases with distance shore. The station at Mjóanes, Thingvallavatn Lake, is located around 100 km west Eyjafjallajökull during after eruption 2010, fluoride increased 10-20 μg/l to 90 annual average elevated 11 28 μg/l. From 1980 1998, pH rainwater Írafoss due emissions reductions anthropogenic sulphur. Since...
