Zusammenfassung: | Levels of amphetamine, methamphetamine, cocaine, and benzoylecgonine (BE), the metabolite of cocaine, were quantitated by solid phase extraction and liquid chromatography with tandem mass spectrometry (LC/MS/MS) in Forester Creek in San Diego County, CA, and in raw wastewater from the region’s sewage treatment plant. Drug residues in these surface waters were detected with 100% frequency. Mean concentrations were 0.022 ± 0.016, 0.450 ± 0.398, 0.024 ± 0.014, and 0.019 ± 0.012 μg/L for amphetamine, methamphetamine, BE, and cocaine respectively.
