Sammenlignende laboratorieprøving (SLP) – Industriavløpsvann SLP 1655

Abstract

As part of the control with industrial effluents, the Norwegian Environment Agency and the Secretary of County Governor for the Environment have instructed a series of industrial companies to periodically report the composition of their effluents. The companies have to fulfil certain analytical quality requirements. This may be achieved by participating in interlaboratory comparison exercises (SLP). In accordance with an agreement between NIVA and the Norwegian Environment Agency, NIVA organises two exercises yearly. The samples distributed represent industrial effluent water. ... 86 % of the results in exercise 1655 were acceptable, which is comparable to results from the previous exercises (table 1). The practice of continuous quality assurance [Hovind 2006 et. al] is a prerequisite to be able to evaluate methods and routines. Standard reference materials (SRMs) are recommended for controlling the results and methods, but in lack of SRMs, samples from previous exercises may be used.

Ved en sammenlignende laboratorieprøving (SLP) arrangert i september – desember 2016 deltok 59 laboratorier i bestemmelse av pH, suspendert stoff (tørrstoff og gløderest), sum organisk stoff (biokjemisk oksygenforbruk, kjemisk oksygenforbruk, totalt organisk karbon), totalfosfor, totalnitrogen og tolv metaller i syntetiske vannprøver. Ved denne SLPen, som har sitt utgangspunkt i Miljødirektoratets og fylkesmennenes kontroll med industriutslipp, er 86 % av resultatene ansett som akseptable. Dette er på samme nivå som disse SLPene har ligget på de seneste årene. Generelt viste de aller fleste parameterne en kvalitet som er sammenliknbar med den siste SLPen. Metallene viste generelt noe forbedring fra tidligere år, mens for suspendert stoff var det færre akseptable resultater for både tørrstoff og gløderest.
