Determination of cyclic volatile methylsiloxanes in water, sediment, soil, biota, and biosolid using large-volume injection-gas chromatography-mass spectrometry

► A series of methods to determine D4, D5, and D6 in water, sediment, soil, biota, and biosolid were developed. ► Sealed extraction system were used to avoid volatilization and contamination by indoor/laboratory air. ► Large volume injection enhanced detection limits for cVMS in environmental samples. ► cVMS were stable for 3 weeks in WWTP influent and effluent stored at 4 °C and in sediment stored at −20 °C.
