Scope: This standard specifies a gas chromatography-mass spectrometry method for the determination of six phthalate compounds in soil and sediments. This standard applies to dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP), butyl benzyl phthalate in soil and sediments Determination of six phthalate ester compounds including BBP, di(2-ethylhexyl) phthalate (DEHP) and di-n-octyl phthalate (DNOP). Other phthalate compounds can also be measured by this method after verification. When the sampling volume is 10.0 g, the extraction volume is 20.0 ml, and the injection volume is 1.0 µl, the detection limit of this standard method for determining phthalate esters is 0.02 mg/kg ~ 0.05 mg/kg, and the lower detection limit is 0.08 mg /kg～0.20 mg/kg. See Appendix A for details.
