Directory entires that have specified Sweden as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

This project is now part of the project : Acidifying and Eutrophifying Substances in Air and Precipitation
National Environmental Monitoring in Sweden. The project is included in a European Monitoring and Evaluation Programme network (EMEP). The subprogram main task is to check if international agreements as UN Convention on Long range Trans-boundary Air Pollution (CLTRAP) is followed. The measurements follow up the Swedish national generational goals "Natural Acidification Only", "A Non-Toxic Environment" and "Clean Air". The network comprises 10 stations, out of which three are in north Sweden, the two one are in AMAP area. Air chemistry is monitored by diffusion samplers. The following compounds are measured: SO2, SO4, tot-NH4, tot-NO3, soot, NO2. Precipitation quality is monitored following measured compounds: SO4-S, NO-N, Cl, NH4-N, Ca, Mg, Na, K, pH, EC. Metals in air and precipitation are analysed only at one north station (Bredkälen), and include: As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn, V, Hg, methyl-Hg.
This project is a merging of two previous projects: "Pollutants in air, daily values" and "Pollutants in air, monthly values, Precipitation chemsitry, monthly sampling, Ozone measurements, passive sampling. S- and N- Components in air with passive sampling."
National Environmental Monitoring program in Sweden. The subprogram "Acidifying and Eutrophifying Substances in Air and Precpipitaiton" is included in a European Monitoring and Evaluation Programme network (EMEP) and in the national program "Air and Precipitation Chemistry Network" (LNKN). The EMEP network currently comprises 4 stations, out of which 1 is located in northern Sweden, close to AMAP area. The LNKN measurements of substances in air are currently performed at 9 stations and in precipitation at 16 stations. Monitoring is performed Daily within the EMEP network and monthly within the LNKN network.
