Sammenlignende laboratorieprøving (SLP) – Industriavløpsvann. SLP 1247

Abstract

Ved en sammenlignende laboratorieprøving (SLP) arrangert i november – desember 2012 deltok 66 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 denne SLPen, som har sitt utgangspunkt i Klifs og fylkesmennenes kontroll med industriutslipp, er 82 % av resultatene ansett som akseptable. Dette er omtrent på det kvalitetsnivået som disse SLPene normalt pleier å ligge. Generelt viste metallbestemmelsene god kvalitet og var på linje med den siste SLPen. Det var en fremgang i kvalitet for biologisk oksygenforbruk og totalt organisk karbon. Denne SLPen viste imidlertid, i likhet med den siste, en viss tilbakegang for pH sammenliknet med tidligere år. Videre må fortsatt kvaliteten av bestemmelsen av totalnitrogen betegnes som lite tilfredsstillende.
