On-line solid phase extraction (SPE) was coupled to liquid chromatography with tandem
mass spectrometry (LC/MS/MS) to detect 19 compounds from a diverse group of
pharmaceuticals, pesticides, personal care products and steroids at a concentration as low as
ng L<sup>-1</sup> in drinking and surface waters was studied. All results displayed a good degree of
reproducibility, with relative standard deviations (RSD) of less than 12 % for all
compounds. Matrix effects were observed for some compounds without exceeding more
than 25%. Method detection limits were in the range of 2 to 25 ng L<sup>-1</sup> except for estriol
with a value of 50 ng L<sup>-1</sup>. The recoveries varied from 87 to 110 % in surface waters. The
analysis of various water samples with the detection and quantification of some of the
selected compounds were also reported. This method was preferred over traditional offline
procedures since it can minimize tedious sample preparation and increases
productivity. Includes 12 references, tables, figures.
