Table 2. The background exposure level of the six priority controlled PAEs.

	DMP	DEP	DBP	BBP	DEHP	DNOP
MIXPs	2.52±1.52	1.51±0.40	3.34±1.63	ND	ND	27.57±14.92
MIXPs+GMS	1.61±1.28	1.30±0.49	3.47±1.77	ND	ND	19.68±7.97

Note: n = 5, unit: 10⁻³ mg/kg/d; ND, the background exposure level of BBP and DEHP were below the LOD of the detection method.
