PHARE interlaboratory studies in Slovenia

In 1996, 1997 and 1999, three interlaboratory studies were organised in PHARE countries to assess the overall accuracy of the laboratory routine practices in these countries. Trace metals, wastewater parameters and organic pollutants were determined in the samples of various matrices. The reported results were statistically evaluated. The laboratories showed a very good performance in trace metal and wastewater parameter analyses but in the case of organic pollutants their performance was poorer.
