Abstract
The working group “Analyses in Biological Materials” of the German Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area (MAK Commission) has evaluated six different procedures for the calculation or estimation of the detection and quantitation limits determined in the validation process of biomonitoring methods. Using the example of the biomonitoring parameter 1-hydroxypyrene in urine, the advantages and disadvantages of these approaches are considered, and all procedures are critically evaluated and discussed. In summary, the Commission does not recommend one preferred method for the calculation of detection and quantitation limits, but rather a careful consideration and fit-for-purpose check of the chosen procedure. A thorough documentation of the selected approach and its results is an essential part of a method description.
