Vergelijking van RIVM- en ECN-resultaten van de Analyse van Regenwater

Synopsis

Concentration levels in the Netherlands National Precipitation Chemistry Network (LMR) might be systematically increased by outliers. In the study on systematically increased results in the LMR, it is examined whether increases can be attributed to the method of analysis. For this purpose 24 samples were analyzed by RIVM and ECN and the results compared. For the main components the results of RIVM and ECN are sufficiently comparable. the results for sodium and potassium indicate that contamination of the samples of incidentally might have occurred. For the inorganic micro-components iron, lead and copper differences were found which are probably due to the sample pretreatment of RIVM and ECN.
