Note:
= not analyzed. It has to be noted that for all compounds, at least in one, sample concentrations were
found below detection limit ( factor of 10 higher for comparable samples and were not used. High blank concentrations of phenol and isomers of cresol prevent a sensitive
analysis, often leading to concentrations
