We compared four preconcentration-detection methods for tracing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in wastewater: ultrafiltration and covalent affinity resin separation, paired with either reverse transcription-quantitative polymerase chain reaction (PCR) or reverse transcription-digital PCR. Tests were conducted on raw sewage from a campus dormitory septic tank in May 2023. Results show that the concentrations of coronavirus RNA in wastewater enriched by ultrafiltration were higher than those enriched by covalent affinity resin separation, regardless of the detection methods used. Digital PCR exhibited detection rates of 45.4% using covalent affinity resin separation, and 77.3% using ultrafiltration. These detection rates were 36.4% and 72.7% higher than those using quantitative PCR. A correlation coefficient of 0.70 between concentrations measured by quantitative and digital PCR was only observed for samples enriched by covalent affinity resin separation.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"13 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143979363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Cell painting-based phenomics was used to map phenotypic alterations across subcellular structures, and untargeted metabolomics using ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry was employed to assess metabolic changes. Results show that perfluorooctanesulfonic acid predominantly affected the actin cytoskeleton, Golgi apparatus, and plasma membrane, while nanoplastics primarily targeted mitochondria. Combined exposure disrupted the endoplasmic reticulum, RNA, and mitochondria. Perfluorooctanesulfonic acid reduced levels of carnitines, free fatty acids, nucleotides, and sugars, whereas nanoplastics inhibited ceramides, triglycerides, sphingomyelins, and additional free fatty acids. Combined exposure produced a metabolic profile resembling that of nanoplastics, with specific differences attributed to perfluorooctanesulfonic acid. Overall, nanoplastics appear as the main drivers of the co-exposure effects.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"18 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143889358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Traditional methods for detecting aflatoxin B1 such as thin-layer chromatography, high-performance liquid chromatography, enzyme-linked immunoassay, and liquid chromatography–tandem mass spectrometry, have limitations including high costs, complex preparation procedures, and occasionally low sensitivity. Here, we review DNA-based biosensors for aflatoxin B1 detection with emphasis on electrochemical and optical sensors. Electrochemical biosensors are based on electrochemical impedance spectroscopy, amperometry, voltammetry, and potentiometry. Optical sensors involve colorimetry, surface plasmon resonance, fluorescence, and electrochemiluminescence. Sensors combine nano and composite materials, such as gold nanoparticles, black phosphorus nanosheets, graphene oxide, niobium carbide, photonic crystals, and liquid crystals.

Nonetheless, phosphogypsum contains impurities such as heavy metals, fluoride, and phosphate, which can decrease the performance and contaminate the environment, calling for pretreatment or solidification methods. Here, we review phosphogypsum with emphasis on impurities and their hazards, solidification methods, and treatment methods for use in road construction. Solidification involves blending phosphogypsum with inorganic cementitious materials, adding additives, geopolymers, biological treatments, and biochar adsorption. Phosphogypsum can be blended with electrolytic manganese residues, granulated blast furnace slag, and inorganic cementitious materials. Additives comprise polymers, surface modifiers, and curing agents. We observe that solidification methods display more advantages than pretreatment methods. The combination of phosphogypsum with inorganic cementitious materials, polymer surface modifiers, curing agents, geopolymer materials, and biomass materials can effectively solidify various impurities, though the effectiveness varies across different solidification methods. There are four solidification mechanisms: physical encapsulation, chemical precipitation, ion exchange, and adsorption. When solidified in road engineering applications, phosphogypsum show reduced leaching levels of arsenic, lead, while maintaining a good road performance.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"23 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143827622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

High levels of indoor ozone are known to inactivate the virus, yet the impact of low-level tropospheric ozone remains unclear. We thus hypothesized that tropospheric ozone, influenced by seasonal conditions, may mitigate viral spread. We studied the influence of ozone concentration, temperature, and humidity on the COVID-19 reproduction number in three large Israeli cities during 2020–2021. The effect of these parameters was also analyzed in laboratory experiments on viral inactivation. Field results show that in winter, under low temperature and low humidity, the COVID-19 reproduction number decreases with an increase in ozone concentration. In contrast, in the summer, under high temperature and high humidity, the COVID-19 reproduction number increases weakly with an increase in ozone concentration. This seasonal variation is attributed to ozone’s dual effects. Indeed, in winter, ozone inactivates the virus, whereas in summer, ozone primarily impacts human respiratory health, which indirectly favors COVID-19 transmission. Nonetheless, experimental results did not fully align with the field survey, showing increased virus inactivation with an increase in temperature.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"17 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143814081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Here, scandium is used to estimate the natural abundance of lead in surface and groundwater. In pristine groundwater sampled at the Elmvale Groundwater Observatory in southern Ontario, the lead/scandium mass ratio (Pb/Sc) ranges from 1.1 to 1.2, similar to the ratio (1.2) most recently proposed for the Upper Continental Crust. In the Athabasca River of northern Alberta, where dissolved lead is well below the global average for uncontaminated river water, the average Pb/Sc ratio was 2.2 in 2014 and in 2015, consistent with the Pb/Sc ratio recently compiled for soil (2.3). In contrast, the average Pb/Sc ratio in the rivers and lakes of central Ontario was 6.0, reflecting the far larger cumulative inputs of anthropogenic, atmospheric lead in eastern Canada compared to western Canada. Support for this interpretation comes from contemporary snow from southern Ontario with an average Pb/Sc ratio of 400. Despite the profound differences in the geology of the study regions, and ignoring the geochemical processes affecting both elements in the watersheds, scandium appears to be a helpful, simple tool for estimating the natural abundance of lead in surface and groundwater. However, the use of the Pb/Sc ratio in this way depends critically on accurate, precise and sensitive measurements of both elements. While the problems of low level lead determinations are well known, those of scandium may have been underestimated.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"38 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

However, temperature effects on these reactions are unknown, thus we investigate oxocarboxylic acid photoproduction from irradiated oil–water systems. Oil samples include British Petroleum crude, Deepwater Horizon crude, Maya crude from Mexico, SRM 2717a oil from the National Institute of Standards and Technology, and an Alaskan crude. Oils were spread over water and exposed to simulated sunlight for 6 h at 12, 25, and 35 °C, followed by quantifying oxocarboxylic acid abundance and dissolved organic carbon in the water. Treatment with 2,4-dinitrophenyl hydrazine produced hydrazones, enriched using solid phase extraction and analyzed by using electrospray ionization-tandem mass spectrometry. Results show that temperature and oxocarboxylic acid photoproduction exhibit a complex relationship; however, oil behavior was similar with temperature. Dissolved organic carbon increased with irradiation temperature for photosolubilized oil. Deepwater Horizon oil showed high-temperature sensitivity with dissolved organic carbon production of 12.6 ppm at 35 °C versus 6.0 ppm at 12 °C. Low molecular weight species are easily volatilized, while larger molecules require greater photooxygenation to become substantially water soluble.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"38 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
