“…Figure 4 presents the chromatogram of one infant formula powder sample spiked with 1.0 μg·kg − 1 PAH4 standard. Several studies had reported the LODs, LOQs, and recoveries of PAHs from different food material including meat products, tea, fish, and crab [28]; the recoveries ranged from 66% to 138% when detecting 16 PAHs in fresh oysters, shrimp, and Atlantic croaker products, with the LODs and LOQs of 0.02 and 0.06 μg·kg − 1 , respectively [29].…”

A gas chromatography-mass spectroscopy (GC-MS) method was developed to assess the infant exposure assessment from four important polycyclic aromatic hydrocarbon (PAH) markers in infant formula powder: benzo[a]anthracene, chrysene, benzo [b] fluoranthene, and benzo[a]pyrene (collectively referred to as PAH4). e developed method required the addition of an isotopically labeled internal standard, sample extraction under alkali conditions, a saponification step, and a solid-phase extraction purification step. In a controlled spike test, the average recovery rates of PAH4 were 77.3% to 111.8% and the relative standard deviations were 4.8% to 14.2% (n = 6). e quantitative limit (LOQ) and detection limit (LOD) of the method were 0.5 and 0.1 μg·kg − 1 , respectively. e PAH4 content was analyzed in 30 commercially available infant formula powders. e PAH4 content was found to be in the range of 0.1 to 0.87 μg·kg − 1 . Combined with the daily intake of infant milk powder in China, the average and maximum daily exposure of BaP for stage-1 infants in China are 0.45 ng/kg.bw.d − 1 and 1.9 ng/kg.bw.d − 1 and the PAH4 values are 8.6 ng/kg.bw.d − 1 and 18.6 ng/kg.bw.d − 1 , respectively. e PAH4 content in the tested infant formula powders sold in the China were sufficiently low, and all of the tested products were safe for consumption.

“…The water and organic phase composition as well as salt addition for salting-out the analyte were optimized. The best salting-out of ACN is usually achieved by addition MgSO 4 whereas addition of NaCl controls polarity of extraction solvents and thus allows to control the selectivity of the extraction [26]. However, the use of these salts can decrease detection limit and peaks intensity due to deposition of solid NaCl in MS source [29].…”

“…The next step is dispersive solid-phase extraction step that involves further clean-up using several combinations of porous sorbents and salts to remove matrix interfering substances. QuEChERS approach was quickly found application in analysis of many other compounds in various biological and environmental matrices [25,26]. Nowadays, the method is adopted according to target analyte properties, matrix composition, equipment, and analytical techniques available in the laboratory.…”

Development and Application of a Novel QuEChERS Method for Monitoring of Tributyltin and Triphenyltin in Bottom Sediments of the Odra River Estuary, North Westernmost Part of Poland

A Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) extraction method combined with Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) for determination of organotin compounds (OTC) has been newly developed. The novel analytical method was validated and the quality of the results was tested by the use of certificate reference material of freshwater sediment BCR 646. The method was applied in determination of OTC concentration in real samples of bottom sediments collected from the Polish part of Odra River Estuary. The samples came from locations with different anthropogenic impact. Additionally, the extraction recovery of OTC and matrix effect on MS signal response was investigated based on those real environmental samples. It was found that organic compounds and anthropogenic contaminations present in bottom sediments may affect extraction efficiency of the organotin compounds (OTC) and change the matrix effect on MS signal response. The highest concentrations of tributyltin were found in bottom sediments collected from locations in vicinity of the Szczecin harbor and shipyards. The presence of triphenyltin above limit of detection (5 ng TPhT/g of sediment) was observed only in two samples and its concentration was several times lower compared to concentration of tributyltin (from 58 ng/g to 5263 ng/g). In spite of the fact that, the application of TBT-based paints on hull of vessel entering EU ports has been banned by European Commission regulation No. 782/2003 since 2008, the OTC compounds are still present in bottom sediment and pose significant threat to the environment. This threat should be taken into account during dredging of waterways and other hydrotechnical works.

“…In this study, a green, sensitive, and rapid chiral analytical method of oxathiapiprolin was first developed using SFC−MS/MS. Target analytes was extracted based on QuEChERS method due to its simplicity, effectivity, stability, and solvent saving [22]. Moreover, the developed method was applied to monitor the enantioselective dissipation of oxathiapiprolin enantiomers in authentic grape samples under field conditions.…”

Oxathiapiprolin is a chiral fungicide used in China for the prevention and treatment of grape downy mildew, but its potential risk could be inaccurately assessed without distinguishing its enantiomers. In this study, an effective and sensitive chiral analytical method was first established for quantification of oxathiapiprolin enantiomers using supercritical fluid chromatography tandem mass spectrometry. Baseline separation for oxathiapiprolin enantiomers was achieved for less than 3 min by using a Lux Cellulose‐2 chiral column with the resolution of 1.51. The elution order of the eluting enantiomers was identified as (−)‐oxathiapiprolin and (+)‐oxathiapiprolin by an optical rotation detector. The grape samples were extracted by QuEChERS method, with the average recoveries of each enantiomer in grapes were in the range of 88.1–111.8% and the relative standard deviations were less than 18.9%. The enantioselective analysis of the dissipation of oxathiapiprolin in field grape samples showed that (−)‐oxathiapiprolin was dissipated faster than (+)‐oxathiapiprolin. The results indicate that this proposed method could provide data support for the risk assessment of oxathiapiprolin in agricultural produces in a more accurate way.
