A novel method has been developed to simultaneously determine and quantify seven organic UV filters employing liquid (solid)-liquid extraction, derivatization with N-methyl-N-(trimethylsilyl) trifluoroacetamide (MSTFA) and gas chromatography with mass spectrometric detection in various environmental matrices. The UV filters determined were:

Steroid derivatization was investigated by varying the experimental parameters (reagent, reaction time, and reaction temperature) to determine the optimal conditions for individual steroids, and for larger subsets. Three methods of derivatization enhancement were also investigated: the use of sonication, the
