In this review, we systematically introduce the sources of MPs, the interactions between MPs and organic compounds, the factors influencing the adsorption of organic compounds onto MPs, and research advances in investigating the adsorption of organic compounds by microplastics with different techniques. We also point out that the structures of MPs and environmental factors can have distinct effects on the adsorption mechanisms, and the adsorption mechanisms for numerous organic compounds onto MPs are still unclear. Besides, there is a paucity of multi-dimensional models for predicting the adsorption of organic compounds by MPs under different environmental conditions with a single click.

However, the residual risk of abamectin in agricultural products and the environment may be exacerbated by other pollutants, posing greater potential hazards. One such emerging environmental pollutant is <em>N</em>-(1,3-dimethylbutyl)-<em>N</em>′-phenyl-<em>p</em>-phenylenediamine (6PPD), a common tire antioxidant found in various environments, including agricultural products and human urine. Our study is the first to reveal the co-existence of 6PPD and abamectin in water and soil, and it demonstrated that 6PPD significantly enhances the residual persistence of abamectin in environmental media and vegetables. Specifically, 6PPD extended the half-life of abamectin by 79% in pak choi and by 70% in cabbage. Additionally, 6PPD increased the photolysis half-life of abamectin by 191% in water and by 50% on soil surfaces. Furthermore, 6PPD also prolonged the photolysis half-life of four other macrolides in water. This study reveals the mechanism through which 6PPD extends the half-life of abamectin: by scavenging free radicals and inhibiting hydroxylation and oxidation, thus slowing its degradation. And this paper highlights that 6PPD significantly exacerbates the environmental risks and food safety issue associated with abamectin. Moreover, it provides valuable insights for studying the safe use of pesticides in complex environments with multiple contaminants.</p>","PeriodicalId":74,"journal":{"name":"Environmental Science: Processes & Impacts","volume":" 4","pages":" 1013-1024"},"PeriodicalIF":4.3,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stay-at-home orders early in the COVID-19 pandemic led to significant portions of the population spending high fractions of their time at their primary dwelling. Stay-at-HomeChem leveraged a network of indoor chemistry researchers to study indoor air quality and surface chemistry in their homes (March-April 2020). Within this effort, glass microscope slides were deployed in kitchens and other rooms in dwellings across the country for time periods ranging from as short as three hours up to three weeks. Overall, results from 10 occupied homes (15 distinct rooms) showed that collected material on this time scale was primarily deposited particles, rather than thick films, based on optical microscopy and profilometry. Raman microspectroscopy and optical photothermal infrared (O-PTIR) spectroscopy showed that organic modes were dominant, including <i>ν</i>(C-H), <i>δ</i>(C-H), and <i>ν</i>(CO), with minimal contributions from inorganic ions commonly observed in outdoor particulate matter (sulfate, nitrate, or ammonium). Spectral variability within the C-H stretching and fingerprint regions demonstrate differing compositions of deposited particles, often related to cooking activities (<i>e.g.</i>, organic particles from cooking oils). Differences within a single dwelling, highlighted that particles from cooking were key contributors in some other rooms, but not all, reinforcing that sources and ventilation likely led to quite distinct surfaces in different rooms.

We applied the model to the analysis of a large body of literature data on the equilibrium and kinetic features of sorption of a wide range of contaminants by diverse types and sizes of plastic particles.

The greater degree of polymer crystallinity reported for smaller particles may underlie our findings that the intraparticulate contaminant diffusion coefficient decreases with a decreasing particle size.

Recent studies have identified ammonia and small volatile organic pollutants in poultry farms.

The fate of Sb in the environment is largely controlled by its chemical speciation, as well as the speciation of solid phases (<em>e.g.</em> Mn/Fe-oxyhydroxides) that interact with Sb in soils. Microbes have the capacity to facilitate a multitude of oxidation and reduction reactions in soils. Therefore, they exert control over the reactivity of Sb in the environment, either directly and/or indirectly, by changing Sb speciation and/or affecting the redox state of soil solid phases. Here, we outline processes that determine the behaviour of Sb in soils. We conclude that based on laboratory studies there is a good theoretical understanding of pure soil components interacting with Sb species. However, comparatively little is known concerning the contribution of these interactions in complex natural systems that are dynamic in terms of biogeochemical conditions and that can hardly be simulated using laboratory incubations. We note that important biochemical foundations of microbially driven Sb conversions (<em>i.e.</em> molecular constraints on organisms, genes and enzymes involved) have emerged recently. Again, these are based on laboratory incubations and investigations in environments high in Sb. In this regard, an important remaining question is which microorganisms actively impact Sb speciation under real-world conditions, in particular where Sb concentrations are low. Multiple dissolved Sb species have been described in the literature. We note that more analytical development is needed to identify and quantify possible key Sb species in natural systems, as well as anthropogenically impacted environments with only moderate Sb concentrations.

In a recent study, we described a novel but complementary electrochemical approach to quantify EECs of 10 pyrogenic dissolved organic matter (pyDOM) and 6 standard/reference natural organic matter (NOM) materials without mediation using square-wave voltammetry (SWV) in dimethyl sulfoxide (DMSO). Comparison of the results obtained by MCA and SWV showed that SWV in DMSO gave larger EECs than MCA, by several-fold for NOM and 1–2 orders of magnitude for pyDOM. In this study, we describe an improved protocol for calibration of the SWV/DMSO method, which largely eliminates the difference in EECs from SWV and MCA for the standard/reference NOM samples. The results show that values obtained <em>via</em> the SWV method depend on the specific redox standards used for calibration (<em>i.e.</em>, calibrant model compounds), with slopes that span 1.5 orders of magnitude due to variations in current response factors. For pyDOM, the higher values of EEC obtained by SWV were further verified and rationalized. Like the calibrant model compounds, it is proposed that the relatively large EECs for some pyDOM samples from high-temperature chars reflect a combination of hydrodynamic influences in our electrochemical cell, primarily related to electrode surface area to volume ratio and pyDOM size. A detailed explanation of the calibration method, choice of working electrode, DOM sorption effects, and cosolvent effects are discussed.
