Sweden EMEP air and precipitation chemistry

Updated 2012-07-19

The subprogram main task is to check if international agreements as the UN Convention on Long Range Transboundary Air Pollution (CLTRAP) are followed. EMEP = European Monitoring and Evaluation Programme. The network comprises 10 stations, out of which three are in northern Sweden. Air chemistry is monitored by diffusion samplers. The following compounds are measured: SO2, SO4, tot-NH4, tot-NO3, soot, NO2, O3 Precipitation quality is monitored by samplers with lid, open only when it rains. The following compounds are measured: SO4-S, NO-N, Cl, NH4-N, Ca, Mg, Na, K, pH, EC. Ozone near ground is analyzed every hour and is part of an European warning system PM10 is particles Metals in air and precipitation is analysed at Bredkälen only. The following elements are analyzed: As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn, V, Hg, metyl-Hg.
