“…PFPeA and PFBS were often over recovered when both acidified versions of QuEChERS were employed. Few studies that employing QuEChERS acidified with formic acid for PFPeA and PFBS were found [52][53][54]. Previous studies did not report unusual recoveries for these compounds.…”

This study aimed to develop multi-residue methods for the extraction of organic pollutants in mussels (Mytilus galloprovincialis), including 11 pharmaceuticals, 5 pesticides, 5 perfluoroalkyl substances (PFASs) and 2 illicit drugs. The combination of 4 different QuEChERS methods and 12 clean-ups (a total of 44 combinations) were tested. QuEChERS included acidified (AQ), non-acidified (SQ) and their miniaturized versions. The clean-ups included 6 different conventional dispersive solid phase extraction (dSPE) plus 2 enhanced matrix removal (EMR-Lipid) and 4 SPE procedures (including sorbents focused on phospholipid removal and polymer-based). After sample analysis via HPLC-MS/MS, the three methods that provided the best results were validated in terms of linearity, accuracy, precision, sensitivity and matrix effect. The methods selected were the combination of (i) SQ and EMR-Lipid, (ii) AQ and Z-sep+ bulk based dSPE and (iii) AQ and graphitized carbon black (GCB) based dSPE. Recoveries at two concentration levels (50 and 500 ng/g) ranged 53.9-124.0%, 58.5-124.0% and 60.3-127.0%, respectively and limits of detection (LODs) were <10 ng/g for most analytes using any of the methods. The three methods were tested in non-spiked mussel samples purchased in local markets, but organic pollutants were not detected in any sample.However, the methods probed to successfully extract a wide range of organic pollutants in mussel samples from the market and from bioaccumulation trials.

“…In the coastal areas of Bangladesh, the highest concentration of PFBA found in shell sh was 0.66 μg/kg [33], which was nearly one tenth of 6.07 μg/kg in this study. PFBA was often found in soil, sediment, irrigation water, tap water, seawater, crops, vegetables and fruit [12,29,30,34,35]. Considering that most shell sh had biological habits of benthic and lter-feeding [36], it was not di cult to explain why the PFBA concentrations in shell sh were higher than that in sh and crustacean samples.…”

ObjectiveThe purpose of this investigation was to monitor the contamination characters and spatial and temporal distributions of 23 Per uorinated alkyl substances (PFASs) in seafood along South China Coastal Regions. The exposure risks of PFOA and PFOS to human health in marine aquatic products were also evaluated. MethodsA total of 844 samples including 359 shes, 391 shell shes and 94 crustaceans were collected from Guangdong, Guangxi and Hainan provinces. The samples were extracted and puri ed using a modi ed QuEChERS procedure and analyzed by UPLC-MS / MS. The statistical analysis was performed in view of the detection of different PFAS components in variety of shes, shell shes and crustaceans, respectively. ResultsSixteen PFASs were detected in the survived samples and the total detection rates reached to 99.21 %. The highest ∑PFASs in each sample was 28.27 μg/kg, and the average and medium values of ∑PFAS were 1.83 μg/kg and 1.18 μg/kg, respectively. PFOS and PFBA have been considered as predominant PFAS components with corresponding pollution contribution rates of 29.14% and 24.71%, respectively. However, it is noted that PFNA and PFBS were primarily enriched in the oyster and mussel. During the period of this investigation (2014-2016), ∑PFAS average concentrations turned out constantly rising trend and new pollution component PFHxS detected in 2016. ∑PFAS concentrations of Guangdong, Guangxi and Hainan provinces were approximately at similar level. ConclusionThe contamination status of PFASs were getting worse in South China Coastal Regions. Safety and risk exposure assessments of PFOA and PFOS via daily diet intakes showed relatively low to local residents.

“…Organic acids could be removed by silica microspheres bonded with amidogen, which was upgraded and replaced by primary secondary amine (PSA), while graphitized carbon black (GCB) has better adsorbing capacity on chlorophyll [16]. Some solidphase extraction (SPE) methods based on these materials have been widely used in the analysis of pesticide residues and pollutants in vegetables and herbal plants [17][18][19], especially the quick, easy, cheap, efficient, rugged, and safe (QuEChERS) method which was the most popular in this field in recent years [20][21][22].…”

A new determination method of 1-deoxynojirimycin (1-DNJ) in mulberry leaves based on ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) has been developed. Dried and crushed mulberry leaves’ sample was extracted by MeCN-water solvent, purified by graphitized carbon black (GCB) and primary secondary amine (PSA) to remove organic acids and pigments, and then analyzed after attenuation and filtration. The calibration curve showed linearity in the concentration range of 10–500 ng/mL, with the correlation coefficient of 0.998. Recoveries of spiked 1-DNJ at three fortification levels ranged from 94.6% to 96.4%, with relative standard derivation below 1.2%. Additionally, the matrix effect was assessed as negligible. Compared with methods by gas chromatography (GC) and liquid chromatography (LC) via real sample detection, the proposed method acquired better stability and detection efficiency. These results proved that this method has advantages of simple operation, complete purification, small pretreatment loss, good precision and accuracy, and high determination specificity, which is suitable for massive monitoring and precise quantitation of 1-DNJ in mulberry leaves.
