Heavy Metals and Aquaculture For oppdrettsanlegg en det vesentlig at innholdet av tungmetaller er under kontroll. Dette gjelder først og fremst kobber. Landbaserte anlegg, og særlig ved gjenbruk av vann er kontinuerlig overvåking viktig. Selv ved kortvarige nivåer kan gi stor skade, det er derfor viktig med en rask tilbakemelding. Vi har nylig gjennomført et pilotprosjekt på anlegget ved Nofima AS på Sunndalsøra. Resultatene viser at metoden med fordel kan brukes til formålet:
Continuous analyses of zinc, iron, and copper for a time period of four months (middle of January to middle of May, 2004), in polluted river water (Raubekken) at Løkken Verk, Norway. The point in red are results from ICP-MS analyses.
Continuous remote monitoring of zinc, cadmium and lead. Scrubbing wastewater added NH4Cl (to 0.05M). DPASV, 120 s dep. time at -1300mV, scan rate 15 mV s-1, mod. pulse 50 mV. Heimdal incineration plant outside Trondheim
Continuous monitoring of mercury in purified scrubbing water at Heimdal incineration plant Trondheim, Norway.
An interesting new project:Forecasting of earth quakes Some indications show that there is an increase of the level of heavy metals in the groundwater prior to an outbreak of an earth quake. Automatic monitoring of heavy metals can then be used for such forecasting. A collaboration with geologists at University of Stockholm in Sweden is established to work out these new possibilities.
