Abstract

Close
- This report describes concentrations in air of sulphur compounds, soot, nitrogen compounds andozone in Sweden between 1985-1998. Time trends of concentration in precipitation and depositionof sulphate, nitrate, ammonium, acidity, base cations and chloride in six different regions coveringSweden are evaluated during the period 1983-1998. Trends of heavy metals in precipitation havebeen analysed for the period 1983-1998 and the change in heavy metal concentration, 1975-1995, inmosses is described.Data used in the trend analyses originates from measurements performed at six Swedish EMEPstations and from approximately 25 stations within the national Precipitation Chemistry Network.Two different statistical methods, linear regression and the non-parametric Mann Kendall test, havebeen used to evaluate changes in annual mean values.
