However, the mutagenic potential of PM remains unclear. This study aimed to provide a comprehensive description of genetic mutations and mutagenic signatures resulting from chronic exposure to PM₁₀ or PM_2.5. Using whole exome sequencing, we identified driver mutations and mutational signatures in A549 cells, a lung epithelial cell model subjected to weekly exposure to either PM₁₀ or PM_2.5, for a period of 28 weeks. The number of single nucleotide variations, insertions, and deletions increased depending on the duration of exposure. PM₁₀ generated the highest number of genomic alterations. Amplifications in SYK (oncogene) and mutations in NCOR1 (tumor suppressor gene) were prevalent in cells exposed to either PM₁₀ or PM_2.5; however, other mutations were exclusive, such as TP53 and ANK3 for PM₁₀, and ERCC1 and ERCC2 for PM_2.5. Different p53-related signaling pathways were most enriched by driver mutations upon exposure to both PM₁₀ and PM_2.5, particularly the glucose deprivation pathway. Exposure to either PM₁₀ or PM_2.5 resulted in high frequencies of C>A substitutions and one-base insertions/deletions in microhomology sites. The single-base substitution (SBS) signature SBS05, related to the nucleotide excision DNA repair pathway, contributed the most to both PM₁₀- and PM_2.5-exposed cells. The contribution of signature SBS18, related to oxidative stress, was observed in cells exposed to either PM₁₀ or PM_2.5, but a greater contribution was observed in PM_2.5-exposed cells. In addition, SBS03 and SBS36, which are related to different DNA damage repair mechanisms, were observed more frequently in PM₁₀-exposed cells. We assessed the mutagenic potential of PM₁₀ and PM_2.5, as a complete mixture, identifying mutated driver genes and mutational signatures generated by chronic PM exposure, which could contribute to the development of cancer, cardiovascular, and digestive diseases.</p>","PeriodicalId":93933,"journal":{"name":"Chemosphere","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142649846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the impact of biochar addition on the physicochemical properties of arid and semi-arid soils containing microplastics, while also assessing its effect on Barley (Hordeum vulgare) yield under drought stress. The experiment was conducted in a glass greenhouse. Plastic pots containing 3 kg of soil were each planted with 6 barley grains. Biochar was applied at three doses (B0 = 0 g biochar/kg soil, B1 = 6 g biochar/kg soil, B2 = 10 g biochar/kg soil), while microplastics were added at three levels (M0 = Control without microplastics, M1 = 0.5 g/kg soil, and M2 = 1 g/kg soil) on the same sowing date. Water stress was induced when the plants reached the four-leaf stage. ANOVAs and Tukey post-hoc tests were employed for multiple mean comparisons of soil and plant parameters. Drought stress and microplastics negatively influenced soil parameters namely soil moisture, organic carbon, and nitrates, while also affecting electrical conductivity and pH. Biochar exhibited minimal effect on soil properties but significantly altered pH, nitrates, and total CaCO₃. Plant chlorophyll levels decreased under stress, particularly with microplastic dose M1. However, biochar and microplastics enhanced chlorophyll a content, except for dose B1 of biochar, which leads to a decrease in chlorophyll b (0.91 ± 0.138 μg/g FM). Microplastics, at dose M2, improved chlorophyll b content (1.11 ± 0.090 μg/g FM). Aboveground biomass, leaf area, and yield were generally unaffected by tested stresses. Nonetheless, barley grain yield decreased in biochar and microplastic dose M1 (0.47 ± 0.108 g/plant), while it improved with microplastic dose M2 (0.65 ± 0.168 g/plant). Leaf relative water content increased under water stress and microplastics but not with biochar alone. Interaction between microplastics and biochar enhanced plant water content. Drought stress and microplastics diminished soil parameters, whereas biochar lowered nitrates and pH without significantly affecting soil organic carbon. Plant productivity parameters generally exhibited no significant change under water stress, microplastics, or biochar, except for yield and chlorophyll pigments.</p>","PeriodicalId":93933,"journal":{"name":"Chemosphere","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142649812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the fluorescence intensity of macromolecular proteins and small molecular acids decreased. Simultaneously, the average growth rate of transmembrane pressure (TMP) reduced by approximately 0.4 kPa/d. The species abundance and diversity of activated sludge increased, promoting the growth of dominant bacteria, all while maintaining low energy consumption. The aeration intensity had relatively little impact on system operation, and the force of the annular electric field was greater than the force of aeration.

Iron-containing coagulant was widely used in the flocculation process. Therefore, this study investigated the impact of residual iron-containing coagulants on pollutant degradation by the ionizing radiation process. Results showed that the absorbed dose required for complete removal of 50 mg/L bisphenol A decreased from 5 kGy to 2.5 kGy in the presence of 100 μM typical iron coagulant (FeCl₃). BPA degradation efficiency increased with the increase of FeCl₃ dosage over a wide pH range (3.0 to 10.0), and the TOC removal efficiency increased from 20% to 45% with the addition of 300 uM Fe(III). The mechanistic investigation demonstrated that ^•OH was the primary reactive species responsible for BPA degradation. The residual iron coagulants (FeCl₃) significantly enhanced the degradation and mineralization efficiency. Under suitable pH conditions (3.0 to 6.0), the reducing reactive species (e_aq^‒ and ^•H) could effectively reduce Fe(III) to Fe(II), which then reacted with H₂O₂, thus inducing in-situ Fenton reaction to generate more ^•OH, thus promoting the radiolysis degradation of micropollutants.

In this context, a continuous atmospheric microplastics monitoring study was conducted at Carlini Argentine Antarctic Station located in the southwest of 25 de Mayo (King George) Island (South Shetlands). Passive samplers were installed at three locations throughout the station, chosen based on the intensity of human activity and proved to be effective in collecting atmospheric particles over a one-year study period. Micro-FTIR and micro-Raman spectroscopies were used to characterize the suspected microplastic particles. These techniques revealed a wide variety of plastic polymers compositions and industrial dyes associated with textile and plastic materials. Microfibers were found to be the predominant particle form, constituting approximately 80% of the particles detected at each sampling point. Semi-synthetic cotton, polyester, and polyamide were widely detected, along with other plastic compositions. Micro-Raman spectroscopy confirmed the presence of indigo blue, reactive blue 238, and copper phthalocyanine on both synthetic and semi-synthetic fibers, representing the first report of these types of anthropogenic pigments in the Antarctic atmosphere. The results suggest a significant role of short-range transport from local human activities; however, the potential influence of large-scale atmospheric patterns should also be evaluated.
