“…Beforehand, the collected crop samples were freeze-dried at −60 °C for 24 h. The sub-PAHs in crop roots were extracted and purified according to the previous studies. , Briefly, 30 mg (dw) of the root samples was extracted with acetonitrile. After the extracts were purified with MgSO 4 , PSA, and C18, the supernatant was centrifuged at 12,000 rpm for 20 min and then analyzed by HPLC (Ultimate 3000, Thermo Scientific).…”

Substituted polycyclic aromatic hydrocarbons (sub-PAHs) are receiving increased attention due to their high toxicity and ubiquitous presence. However, the accumulation behaviors of sub-PAHs in crop roots remain unclear. In this study, the accumulation mechanism of sub-PAHs in crop roots was systematically disclosed by hydroponic experiments from the perspectives of utilization, uptake, and elimination. The obtained results showed an interesting phenomenon that despite not having the strongest hydrophobicity among the five sub-PAHs, nitro-PAHs (including 9-nitroanthracene and 1-nitropyrene) displayed the strongest accumulation potential in the roots of legume plants, including mung bean and soybean. The nitrogen-deficient experiments, inhibitor experiments, and transcriptomics analysis reveal that nitro-PAHs could be utilized by legumes as a nitrogen source, thus being significantly absorbed by active transport, which relies on amino acid transporters driven by H+-ATPase. Molecular docking simulation further demonstrates that the nitro group is a significant determinant of interaction with an amino acid transporter. Moreover, the depuration experiments indicate that the nitro-PAHs may enter the root cells, further slowing their elimination rates and enhancing the accumulation potential in legume roots. Our results shed light on a previously unappreciated mechanism for root accumulation of sub-PAHs, which may affect their biogeochemical processes in soils.

“…The typical methods for POP studies are gas chromatography with electron capture detector (GC-ECD) (most sensitive to halogenated compounds) [ 15 , 16 ], mass selective detector (including high-resolution mass detectors) (GC-MS, GC-MS/MS, GC-HRMS) [ 17 , 18 , 19 ], and time-of-flight detector (GC-TOF, GC Q-TOF) [ 20 , 21 ]. Also, due to their lyophilicity, all POPs dissolve in various solvents, which makes it possible to detect them using liquid chromatography with a mass selective detector (HPLC-MS/MS) (albeit on a much smaller scale compared to gas chromatography) [ 22 , 23 ].…”

Persistent organic pollutants (POPs) are well-known contaminants that raise serious concerns, even more than 20 years after they were banned. Their worldwide distribution and persistence necessitate continuous monitoring in all components of the environment. The most challenging issues of POP regulation are associated with international water resources because their solutions require international cooperation in environment protection. This review provides data on various POPs (DDT, HCH, endrin, dieldrin, and PCBs) and their concentrations in aquatic organisms inhabiting the Amur River basin, one of the most poorly explored regions of Northeast Asia. Most studies have been conducted in the Songhua River (China), a tributary of the Amur River, which indicates that large inland bodies of water, especially those of international importance, require more extensive research.

“…Gas chromatography-mass spectrometry (GC–MS) and Liquid chromatography-mass spectrometry (LC-MS) have been used to detect carboxyl compounds in Chinese Baijiu ( He et al, 2021 , Liao & Li, 2013 , Liao & Zhou, 2019 ). However, GC–MS is suitable to detect non-polar and semi-polar compounds ( Baroudi, Al-Alam, Chimjarn, Delhomme, Fajloun, & Millet, 2020 ), GC–MS with derivatization and LC-MS are specifically targeted at polar and semi-polar compounds ( Proestos et al, 2006 , Sharma et al, 2018 ), meanwhile, carboxyl compounds in Chinese Baijiu are polarity diversity and exist in a low concentration, leading to a poor-coverage detection of carboxyl compounds in Chinese Baijiu ( Jia et al, 2020 , Son et al, 2018 ). Chemical derivatization is capable of improving the overall analytical performance of LC-MS ( Zhao & Li, 2020 ).…”
