Monitoring of air quality and deposition.
Heavy metals: Bulk sampling of precipitation monthly. As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, V, Zn Acidifying compounds: Daily sampling of precipitation for major ions. Conductivity, pH, Cl, NO3, SO4, Mg, Ca, NH4, Na, K Daily filter sampling for sulphate, sulphur dioxide, nitrate+nitric acid and ammonium+ammonia in air. Continuous monitoring of SO2, NO2, O3
Heavy metals: Bulk samples of precipitation. Analysis: ICP-MS. Laboratory: Finnish Meteorological Institute (FMI). Acidifying compounds: Bulk precipitation samples for major ions. Filter sampling for sulphate, sulphur dioxide, nitrate+nitric acid, ammonium+ammonia. The methods are from the EMEP manual. Laboratory: Finnish Meteorological Institute (FMI).
The laboratory of FMI is accredited for analysis of heavy metals and major ions.
