However, current analytical and separation techniques are often limited in the breadth of chemistry targeted, most often targeting less than 15 compounds. Challenges to successful methods with this compound group include chromatographic resolution, quantitation across diverse concentration ranges, and sample preparation due to the chemical similarity of these compounds. This project describes the development of a selective ion monitoring gas chromatography mass spectrometry method for quantitation of 29 phthalates and two phthalate replacements along with considerations for quantitation, sample cleanup, and standard storage. Our range of phthalates includes less-studied ones like bis(2-propylheptyl), diundecyl, didecyl, and ditridecyl. Analytical performance included limits of detection ranging from 17-230&amp;nbsp;ng/mL and robust reproducibility with relative percent differences below 8% for complex matrices. Two calibration ranges were used to accommodate the wide dynamic range of phthalate concentrations observed in real samples. Method application was demonstrated with edible oils (n = 12) and silicone wristbands (n = 18), representing dietary and personal exposure pathways. Sample preparation strategies, including solid phase extraction were evaluated to mitigate matrix interferences. In addition, compound storage stability was assessed over 133 days to inform best practices for standard preparation and handling. The finalized method demonstrates the uniquely large compound ranges for some phthalates and the importance of analyzing a wide variety of these compounds, making it a valuable foundation for comprehensive environmental monitoring of phthalates and their alternatives.&lt;/p&gt;

In this study, the collection of butter clams (Saxidomus giganteus) was spatially and temporally paired with deployment of sediment pore water passive samplers at 20 locations in the Puget Sound region of the Salish Sea in the Pacific Northwest, USA, within adjudicated usual and accustomed tribal fishing grounds and stations. Clams and passive samplers were analyzed for 62 individual PAHs. A linear regression model was constructed to predict PAH concentrations in the edible fraction of butter clams from the freely dissolved fraction (C) in porewater. PAH concentrations can be predicted within a factor of 1.9 ± 0.2 on average from the freely dissolved PAH concentration in porewater using the following equation: PAHClam=4.1±0.1×PAHporewater This model offers a simplified, cost effective, and low impact approach to assess contaminant levels in butter clams which are an important traditional food.&lt;/p&gt;

Sample processing includes extraction of PAHs into a solution of ethyl acetate, acetone and isooctane followed by cleanup with dispersive SPE and analysis by GC-MS in SIM mode. Method performance was assessed in spike recovery experiments (500 μg/g wet weight) in three commercially available smoked salmon with 3-11% fat. Recoveries of some 2-, 3- and 5-ring PAHs were improved 50-200% over traditional methods, while average recovery across all PAHs was improved 67%. Method precision was good with replicate extractions typically yielding relative standard deviations &amp;lt;10%, and detection limits were in the low ng/g range. With this method, a single analyst could extract and clean up ≥60 samples for PAH analysis in an 8 h work day.&lt;/p&gt;
