摘要: The deposition of heavy metals (arsenic, cadmium,copper, chromium, nickel, lead and zinc) on the Convention Watersof Oslo Paris Commissions (OSPARCOM) were calculated usingan emission based modelling approach. Emissions taken from theUN-ECE/OSPARCOM/HELCOM Emission Inventory Heavy Metals andPersistent Organic Pollutants. atmospheric transport modelEUTREND was used to calculate heavymetals convention waters. Results obtained for theregions Greater North Sea, Celtic Bay Biscay IberianCoast parts regions Arctic Waters Wider Atlantic.The contributions five major source categories depositionwere calculated. contribution OSPARCOM countries thedeposition as well ofthe non-OSPARCOM a whole Measured airconcentrations underestimated by calculations factorof 2–4 arsenic, cadmium, copper, chromium zinc. For andnickel comparison close 1:1 line. underestimationis most likely due an underestimation emissions. Acomparison between input atmosphericdeposition riverine around Sea acomparison with other studies NorthSea estimated measurements are presented.
