Sammenlignende laboratorieprøving (SLP) Industriavløpsvann: SLP 0940

Abstract

Ved en sammenlignende laboratorieprøving (SLP) arrangert i mai - juni 2009 deltok 79 laboratorier i bestemmelse av pH, suspendert stoff (tørrstoff og gløderest), sum organisk stoff (biokjemisk oksygenforbruk, kjemisk oksygenforbruk, totalt organisk karbon), totalfosfor, totalnitrogen og ni tungmetaller i syntetiske vannprøver. Ved SLPen, som har sitt utgangspunkt i SFTs og fylkesmennenes kontroll med industriutslipp, er 78 % av resultatene ansett som akseptable. Dette er noe lavere enn ved de foregående SLPer. Spesielt var det en nedgang for totalt organisk karbon, totalfosfor og totalnitrogen, og i forhold til den siste SLP-en var det også en nedgang for mange av tungmetallene. Ved denne SLP, som tidligere, ble det påvist at bestemmelse av totalfosfor og totalnitrogen med forenklede metoder ikke gir akseptable resultater ved analyse av denne typen vannprøver.
