“…The R 2 values for 11 analytes were higher than 0.9910. The LODs of other methods for detecting PAEs, such as 0.01−10 μg kg −1 with the QuEChERS method 43 and 0.05−1.8 μg kg −1 with solvent extraction, 44 were higher than the LODs of CDIP (0.01−40 ng g −1 ). The LODs of other methods of detecting APs were 0.02−0.41 ng g −1 for SPE 21 and 0.3−0.4 ng g −1 for microwaveassisted extraction; 17 in contrast, CDIP had LODs of 1.6−13.3 ng g −1 .…”

Intake of endocrine-disrupting chemicals (EDCs) by humans could disturb the metabolism of hormones, induce cancer, and damage the liver and other organs. Phthalate acid esters (PAEs) and alkylphenols (APs) are important EDCs and environmental contaminants. With the increasing use of plastics and nonionic surfactants worldwide, PAEs and APs have entered environmental water and accumulated in edible fish, which are finally consumed by humans. In this study, a coated direct inlet probe (CDIP) based on an atmospheric solid analysis probe, which can rapidly and simultaneously extract both PAEs and APs in fish, was developed. Twelve PAEs and APs were quantified by using a stable-isotope-labeled internal standard. Standard curves of the PAEs and APs having correlation coefficients of R 2 ≥ 0.9837 were obtained. The limit of detection of the PAEs and APs was distributed from 0.01 to 40 ng g–1. The relative recovery of the method was 78–120% between low, medium, and high spiked levels. Combined with principal component analysis, PAE- and AP-contaminated Carassius auratus from different habitats could be identified. Multiple sample analysis mode allowed the extraction of up to 12 samples at once, and the total analysis time (including sample pretreatment, extraction, and analysis time) was less than 10 min per sample, which indicates that CDIP is useful for rapid quantitative analysis.

“…The retention time, qualified ion, quantifier ion pair, and collision energy of each compound are listed in Supporting Information Table S1. The selected PAEs have common characteristic transitions (149 > 121, 149 > 93, and 149 > 65) as described in the literature (Xu et al., 2018). All PAEs were completely separated and good resolutions were observed in terms of retention times and peak shapes.…”

Newly developed magnetic carbon particles prepared from coffee grounds were used as the sorbent for the magnetic solid-phase extraction of eight phthalic acid esters (PAEs) from plastic bottled water prior to their analysis by GC-MS. The method, which uses coffee-ground particles coated with iron oxide, was validated, and exhibited linearities for the eight PAEs, with coefficients of determination above 0.998 in the 0.005 to 0.1 mg/L concentration range. Limits of detection and limits of quantification of 0.00003 to 0.002 mg/L and 0.0001 to 0.005 mg/L, respectively, were achieved, with recoveries (%) ranging between 77% and 120%, and relative standard deviations for intra-and interday precisions below 16.3% at three fortification levels. No PAE residues were detected when the developed and validated method was applied to 10 real plastic bottled water samples. Taken together, the developed magnetic solid-phase extraction method is a useful tool for monitoring phthalate esters in aqueous samples.Practical Application: The development of a new, inexpensive, and efficient magnetic sorption material derived from spent coffee grounds, and its ability to determine phthalate esters in aqueous solutions was described by GC-MS/MS. The developed magnetic solid-phase extraction method is a useful tool for monitoring phthalate esters in aqueous samples.

“…PSA gave low indaziflam‐carboxylic acid recovery (only 7.1%) but satisfactory recoveries of the other analytes. The reason for this phenomenon was that PSA has both primary and secondary amines , which can effectively adsorb indaziflam‐carboxylic acid. MWCNTs, exhibiting special physical and chemical characteristics owing to their extremely large surface area and unique structure, have excellent adsorption ability .…”

“…The ME due to the presence of coeluting components is a significant drawback of LC‐ESI‐MS/M and MEs may enhance or reduce the chromatographic signal of analytes . In this study, the ME could be calculated as follows:

M E false(% false) = false(\frac{K_{m a t r i x}}{K_{s o l v e n t}} - 1 false) \times 100

, where “ K ” corresponds to the slope of the matrix‐matched calibration curves and the working standard calibration curves, respectively . An ME value above 10% would be considered signal enhancement, below 10% would be considered signal suppression, while between −10 and 10% is considered negligible .…”

A simple and efficient multiresidue method using dispersive solid phase extraction and liquid chromatography coupled with tandem mass spectrometry was developed for the targeted analysis of indaziflam and its five metabolites (indaziflam‐diaminotriazine, indaziflam‐carboxylic acid, indaziflam‐triazine indanone, indaziflam‐hydroxyethyl, and indaziflam‐olefin) in pitaya samples (including roots, plants, flowers, peels, pulp, and whole fruit). The analytes were extracted with acetonitrile, and the extracts were purified using multiwalled carbon nanotubes. The method was validated using pitaya samples spiked at 0.5, 5, and 50 µg/kg, and the average recoveries varied from 61.1 to 103.7% with relative standard deviations lower than 12.7% (n = 5). This method exhibited sufficient linearity within the concentration range of 0.1–100 µg/L. The limits of detection and quantification were in the ranges of 0.001–0.1 and 0.003–0.3 µg/kg, respectively. The method was successfully applied to analyze pitaya samples in Nanning, and no indaziflam or its metabolites were detected in the samples analyzed.
