Persistent organic pollutants (POPs) in drinking water and dietary supplements can be sources of xenobiotic pollutants in human body and cause detrimental impacts on human health. In this study, an accurate, precise, sensitive, reproducible, and green method was developed to quantify POPs in water and dietary supplements using stir bar sorptive extraction- gas chromatography- mass spectrometry and isotope dilution mass spectrometry. Different analytical parameters were tested for method optimization. Based on efficiency as well as recovery of the analytes, stirring at room temperature for one hour with water and methanol as solvent was selected as the optimal method. After validation, this method was used to analyze POPs in wastewater samples. The results showed high level of accuracy and precision for most POPs analytes. This method will also be used for analysis of dietary supplement samples and the results will be used for quality assurance and regulation of dietary supplements.
