“…The lowest detection limit in this method was 0.0015 μg/L for PAEs and 0.0003 μg/L for PAHs. Most studies have reported minimum limits of detection (LODs) to be greater than 0.005 g/L for PAEs [ 37 , 38 , 39 ] and 0.2 μg/L for PAHs [ 40 , 41 , 42 ], and the linear range of the proposed method is wider than that of other methods for the detection of PAEs and PAHs. The advantages of this work are (1) the detection of human placental tissue, (2) sophisticated detection instrumentation and inexpensive extraction reagents, and (3) combined extraction and detection of PAHs and PAEs in large quantities.…”

In this study, we evaluated the extraction effect of three different extractants, namely hexane + ether (v/v = 3:1), acetonitrile and ethyl acetate, on polycyclic aromatic hydrocarbons (PAHs) and phthalic acid esters (PAEs) in placenta detected and analysed by triple quadrupole gas chromatography–mass spectrometry (GC-MS/MS). The results showed that n-hexane + ether (v/v = 3:1) had the highest extraction efficiency. Under the optimal conditions, the limits of detection (LOD) for the 10 PAHs were 0.003–0.0167 μg/L with relative standard deviations (RSD) of 1.4–5.48% and detection rates of 68.19–107.05%, and the correlation coefficients were (R2, 0.9982–0.9999). The LODs for the nine PAEs were 0.0015–3.5714 μg/L and the correlation coefficients were (R2, 0.9982–0.9999). The limits of detection (S/N = 3) for the nine PAHs were 0.0015–0.5714 μg/L with relative standard deviations (RSD) of 3.15–8.37%, and the detection rates were 80.45–112.59% with correlations of (R2, 0.9972–0.9998). The method was applied to the analysis of PAHs and phthalates in placenta samples from pregnant women. The method’s accuracy and applicability were demonstrated. In comparison with other methods for the detection of PAEs and PAHs, the method proposed in this paper has a wider linear range, lower minimum detection limit and comparable recovery with good correlation. This paper is dedicated to providing another method for improving the performance of extracting solid tissues.

Magnetic Solid-Phase Extraction of Organic Compounds Based on Graphene Oxide Nanocomposites

Graphene oxide (GO) is a chemical compound with a form similar to graphene that consists of one-atom-thick two-dimensional layers of sp2-bonded carbon. Graphene oxide exhibits high hydrophilicity and dispersibility. Thus, it is difficult to be separated from aqueous solutions. Therefore, functionalization with magnetic nanoparticles is performed in order to prepare a magnetic GO nanocomposite that combines the sufficient adsorption capacity of graphene oxide and the convenience of magnetic separation. Moreover, the magnetic material can be further functionalized with different groups to prevent aggregation and extends its potential application. Until today, a plethora of magnetic GO hybrid materials have been synthesized and successfully employed for the magnetic solid-phase extraction of organic compounds from environmental, agricultural, biological, and food samples. The developed GO nanocomposites exhibit satisfactory stability in aqueous solutions, as well as sufficient surface area. Thus, they are considered as an alternative to conventional sorbents by enriching the analytical toolbox for the analysis of trace organic compounds.

“…Storage of water samples packed in plastic bottles such as PET and PC for a long duration of time and at elevated temperature may increase the migration of phthalates and bisphenols from the plastic bottles. Dibutyl phthalate (DBP) and DEHP are commonly found in the majority of water stored in plastic containers 19,20 . PET plastics may contain low molecular weight phthalates such as dimethyphthalate (DMP), diethyl phthalate (DEP) and dipropyl phthalate (DPrP), along with diisobutyl phthalate (DIBP), DBP, dipentyl phthalate (DPP) and DEHP.…”

Rationale Phthalates and bisphenols were reported as endocrine disrupting chemicals and hence a potential threat to human health. Polyethylene terephthalate bottles are being used to store drinking water and the probability of migration of phthalates and bisphenols from the bottles into the water is high. The migration of analytes with respect to different storage conditions need to be studied. Method A sensitive analytical method for simultaneous determination of seven phthalates and three bisphenols from packaged drinking water was developed using liquid chromatography/atmospheric pressure photoionization/high‐resolution mass spectrometry. The analytes were extracted by dispersive solid‐phase extraction by multiwalled carbon nanotubes. Results The developed method showed linearity from 0.5 to 5000 μg/L with the limit of detection and limit of quantification ranging from 0.5 to 1 μg/L and 1 to 2 μg/L, respectively, for phthalates and bisphenols. The inter‐ and intraday variations were below 10%. The recoveries were in the range of 79.5% to 112%. The migration of phthalates and bisphenols increased with storage time and temperature. Maximum migration was observed for diisobutyl phthalate of 1209.7 ng/L followed by dibutyl phthalate at 777.8 ng/L on 180 days of analysis at room temperature. Migration of bis(2‐ethylhexyl) phthalate was observed to be higher at elevated temperatures, increasing from 14.9 to 514 ng/L. Similarly, migration of bisphenol‐A was increased at 45°C. The results were subjected to analysis of variance (ANOVA) studies and the results showed significant variations of phthalates and bisphenols with respect to storage temperature and time. Conclusion The use of atmospheric pressure photoionization facilitated simultaneous determination of phthalates and bisphenols. The migration of phthalates and bisphenols increased with increasing temperature and storage time. Maximum migration was observed for diethyl, diisobutyl, dibutyl and bis(2‐ethylhexyl) phthalates. This may be attributed to the type of plastic, the processing parameters and recycling.
