Målinger av miljøgifter i luft ved Franzefoss Eide på Sotra og Husøya ved Kristiansund

NILU har gjennomført måleprogram for konsentrasjoner i luft ved Franzefoss Gjenvinning AS sine anlegg ved Eide på Sotra og ved Husøya ved Kristiansund. Ved Eide ble det tatt prøver i luft og analysert for prioriterte miljøgifter som dekloraner, fenoler, ftalater, PFAS, benzotriazoler, organiske tinnforbindelser, samt VOC inkludert D6, ammoniakk (NH3), gassfase HCl og hydrogensulfid (H2S). For de prioriterte miljøgiftene var de fleste prøvene under deteksjonsgrensen. De høyeste verdiene ble observert ved Lokasjon 11 Vannrenseanlegget. Ved Husøya ble det tatt prøver i luft og analysert for VOC inkludert D6, ammoniakk (NH3) og gassfase HCl. Verdiene ved Husøya var lavere enn ved Eide

Coordinated ground-based validation of ENVISAT atmospheric chemistry with NDSC network data : Commissioning phase report

International audienceIn the framework of the coordinated project called CINAMON, a list of ground-based stations associated with the Network for the Detection of Stratospheric Change (NDSC) contribute to the quasi-global validation of ENVISAT atmospheric chemistry data. This paper reports on such activities performed during the Commissioning Phase (CP) of the satellite. After a description of the correlative database generated during this period, preliminary ground-based studies relying on this database give a first picture of the quality of SCIAMACHY ozone and nitrogen dioxide columns, and GOMOS and MIPAS ozone profiles. Illustration of the global mapping of MIPAS ozone profile data is also presented. The paper concludes with perspectives for the Main Validation Phase of ENVISAT
