Abstract
Precipitation collected in East Greenland by a wet-only type of collector for two years, hasbeen analysed for all major ions. The concentrations are lower by a factor of 10 compared to arural site in Denmark and somewhat lower than at the Faroe Islands. A pH value of 5.16seems to be representative of arctic precipitation. Three discernible components appear to bepresent, a sea-spray and a crustal component and a component related to long-rangetransported aerosols from distant combustion sources. The total wet deposition is very small,but the risk of an effect on the sensitive arctic environment cannot be discarded withoutfurther assessment. DOI: 10.1111/j.1600-0889.1986.tb00259.xKeywords
