This study investigated the contents of 5 phthalic acid esters in the soil and peanut from Ningxi and Huazhou farms. 5 PAEs were detected by gas chromatography coupled with mass spectrometry (GC-MS) in soil and peanut. The soil background concentrations of PAEs ranged from 0.438 to 1.624 mg/kg in Ningxi and that range in Huazhou was from 0.468 to 1.235 mg/kg. The results showed that BBP and DEHP were both the major PAEs, and DEHP was the major PAEs of both sites. PAEs in the soil of two sites were contaminated slightly. The PAEs contents in peanut kernels ranged from 2.466 to 8.888 mg/kg and 3.436 to 5.594 mg/kg, respectively. Results show that the order of PAEs concentration of peanut in the both sites was: root > stem > leave > shell.

In this work, Chromabond® HLB was evaluated as an extraction sorbent of a group of seven phthalic acid esters (PAEs; i.e., dipropyl phthalate, DPP, dibutyl phthalate, DBP, diisopentyl phthalate, DIPP, di-n-pentyl phthalate, DNPP, butylbenzyl phthalate, BBP, dicyclohexyl phthalate, DCHP, and di(2-ethylhexyl)phthalate, DEHP) and one adipate (di(2-ethylhexyl) adipate, DEHA) from tap and waste water prior to gas chromatography-mass spectrometry. After the optimization of the extraction conditions (200 mg of sorbent conditioned with 10 mL of acetonitrile and 2 mL of Milli-Q water, extraction of 50 mL of water at pH 6.0, vacuum drying for 20 min and elution with 10 mL of ethyl acetate), a recovery study was developed at different concentration levels in each matrix, which revealed that most of the target analytes could be recovered between 75 and 112%, with relative standard deviation values for all of them below 20%. Matrix effect was evaluated, finding that matrix-matched calibration should be developed for most analytes in both matrices. The limits of quantification (LOQs) of the method were in the 0.82–71 ng L−1 range. The developed method was also applied to the extraction of the target PAEs in different water samples finding some of them, in particular, DNPP in tap water samples, and BBP and DCHP in waste water, but below the LOQs of the method.
