“…In recent years, emerging quantification techniques that do not require pretreatment have become increasingly popular (Anuar et al 2022 ; Jin et al 2022 ; Xu et al 2022 ). Thermal desorption-gas chromatography-mass spectrometry (TD-GC–MS) and pyrolysis gas chromatography-mass spectrometry (Py-GC–MS) exhibit the advantages of high sensitivity, automation, and solvent interferences-free (Humbert et al 2022 ). TD-GC–MS has been found to be effective for the quantification of brominated flame retardants (especially for BDE-209) in curtains and car interiors (Shin and Baek 2012 ); meanwhile, Py-GC–MS has been increasingly used for the detection of PAEs, flame retardants, ultraviolet stabilizers, and bisphenols.…”

Plastic fibers are ubiquitous in daily life with additives incorporated to improve their performance. Only a few restrictions exist for a paucity of common additives, while most of the additives used in textile industry have not been clearly regulated with threshold limits. The production of synthetic fibers, which can shed fibrous microplastics easily (< 5 mm) through mechanical abrasion and weathering, is increasing annually. These fibrous microplastics have become the main composition of microplastics in the environment. This review focuses on additives on synthetic fibers; we summarized the detection methods of additives, compared concentrations of different additive types (plasticizers, flame retardants, antioxidants, and surfactants) on (micro)plastic fibers, and analyzed their release and exposure pathways to environment and human beings. Our prediction shows that the amounts of predominant additives (phthalates, organophosphate esters, bisphenols, per- and polyfluoroalkyl substances, and nonylphenol ethoxylates) released from clothing microplastic fibers (MFs) are estimated to reach 35, 10, 553, 0.4, and 568 ton/year to water worldwide, respectively; and 119, 35, 1911, 1.4, and 1965 ton/year to air, respectively. Human exposure to MF additives via inhalation is estimated to be up to 4.5–6440 µg/person annually for the above five additives, and via ingestion 0.1–204 µg/person. Notably, the release of additives from face masks is nonnegligible that annual human exposure to phthalates, organophosphate esters, per- and polyfluoroalkyl substances from masks via inhalation is approximately 491–1820 µg/person. This review helps understand the environmental fate and potential risks of released additives from (micro)plastic fibers, with a view to providing a basis for future research and policy designation of textile additives.

“…POPs, as volatile substances, are studied mainly by gas chromatography methods. 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.

“…However, this method suffers from several drawbacks, such as long extraction time, excessive amount of extractant, no stirring to accelerate the reaction, and tendency to lead to thermal degradation of analytes. In recent years, there have been significant advances in extraction techniques for organic contaminants in soil media, including ultrasonic extraction [23][24][25][26], solid-phase microextraction (SPME) [27,28], mechanical oscillation extraction [29,30], pressurized liquid extraction (PLE) [31], accelerated solvent extraction (ASE) [32,33], and microwave-assisted extraction (MAE) methods [34][35][36]. For example, ultrasonic extraction utilizes the force of fluctuations to efficiently extract analytes into the solvent, which reduces the consumption of organic solvents and improves efficiency [37].…”

Natural attenuation techniques, renowned for their environmental compatibility and cost-effectiveness, have garnered widespread attention for the remediation of environmental pollution. In this work, we have successfully enhanced the natural attenuation process of organic contaminants in soil by employing biostimulation and bioaugmentation methods to remove pollutants. The results showed that the degradation rate of low molecular weight polycyclic aromatic hydrocarbons (PAHs) reached about 82.5% while medium molecular weight PAHs was about 43.72%, as well as high molecular weight PAHs was about 34.5% even after a remediation process of only 14 days. In addition, the biofortified soil was exhaustively analyzed by high-throughput sequencing, which showed that the dosing of bactericide and surfactants significantly increased the abundance of 16sRNA genes and alkane degradation-related genes. In response to the challenges of detecting and analyzing complex organic pollutants in soil, we have developed an integrated method for the extraction, purification, and detection of organic pollutants in soil, ranging from low to medium concentrations. This approach not only allows for the efficient extraction of organic pollutants from the soil but also facilitates further inference of the degradation mechanisms of these pollutants. Integrating chemical analysis and microbiological techniques, and employing Gas Chromatography-Mass Spectrometry (GC-MS) and High-Resolution Mass Spectrometry (HRMS), we precisely measured and identified organic contaminants in soil and deduced the mechanisms of degradation. These findings are significant for the development of new environmental remediation technologies and strategies, contributing to addressing soil pollution issues exacerbated by industrial activities.
