Therefore, spot-on sampling and identification are pivotal for assessing exposure risks. Corona discharge-based sampling has been utilized for the bioaerosol sampling. However, one of the issues regarding corona discharge-based samplers is the production of reactive oxygen species (ROS) and reactive nitrogen species (RNS), which can alter the viability of bioaerosols and damage nucleic acids. Herein, the use of ionic wind as a possible alternative to reduce ROS/RNS damage to microorganisms was studied. An aerosol-to-hydrosol (ATH) ionic wind (IW) sampler was developed and compared with an ATH electrostatic precipitation (ESP) sampler having the exact physical dimensions in terms of collection efficiency, ROS/RNS production, ozone generation, viability of collected biological particles, and damage to the nucleic acids of the particles. Overall, the ESP sampler showed a higher collection efficiency and less damage to the reproducibility of the sampled bioaerosols than the IW sampler. However, polymerase chain reaction analysis of the sampled bioaerosol nucleic acids showed similar results for both devices. The IW sampler has the potential for both bioaerosol sampling and deactivation, as well as for scenarios requiring neutralized sampled particles or particle deposition on any nonmetallic surface.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"5 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

The diffusion of dust is primarily influenced by wind flow. The surface wind speed exhibits an exponential distribution as height increases. To investigate dust diffusion under the influence of wind shear, a numerical model was developed using real-scale data through computational fluid dynamics. The results indicate that wind shear significantly affects near-ground wind speeds. The ground-level wind speed near the rear of the truck exceeds the dust lift-off speed, reaching over 6 m/s. The acceleration of the ambient wind speed leads to extensive areas of turbulence with increased intensity. The location of the vortex zone represents the primary area of negative pressure. A higher ambient wind speed accelerates the dust discharge and generates a greater negative pressure, reaching -68 Pa at a wind speed of 9 m/s. The dust concentration behind the truck initially increases before subsequently decreasing. Notably, the local dust concentration at a wind speed of 9 m/s is lower than that at a wind speed of 5 m/s. The obstruction of airflow by the truck cab can result in elevated dust levels on the driver's side. Furthermore, high dust concentrations along driving paths necessitate appropriate truck spacing to protect operator health.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"6 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Herein, the accumulation behaviors of As(Ⅲ) and As(V) on pipe scales and polystyrene microplastics (PSMPs) under different water conditions were studied. Additionally, As(Ⅲ) and As(V) accumulation behaviors on pipe scales coexisting with PSMPs were investigated. Results showed that pipe scales played a key role in the accumulation of As (pipe scales = 1.08–4.80 mg/g > PSMPs = 0.02–3.38 mg/g). The adsorption amount of As(Ⅲ) on PSMPs was higher than that of As(V). The addition of PSMPs promoted the accumulation of As(Ⅲ) on pipe scales at pH = 3–8 while inhibiting the accumulation of As(V) on pipe scales at pH = 3–10 due to the competitive adsorption. The oxidation of As(III) and the reduction of As(V) occurred during the accumulation of As(Ⅲ) and As(V) on pipe scales. Notably, PSMPs accumulated on pipe scales were beneficial to the oxidation of As(Ⅲ), potentially reducing the As-related risks.

Aiming at the time-consuming and inefficient characteristics of traditional batch experiments and statistical prediction models in comprehensively capturing PAEs dynamics in soil, an intelligent analysis framework based on machine learning was proposed and developed. In this study, thirty features were incorporated, including soil PAEs-concentrations, pollutant emissions, agricultural inputs, soil physicochemical properties, and climatic parameters. Six data-driven machine learning models were established: Random Forest Regression (RFR), Gradient Boosting Regression Tree (GBRT), Extreme Gradient Boosting (XGBoost), Multilayer Perceptron (MLP), Support Vector Regression (SVR), and k-Nearest Neighbors (KNN). Results showed that the MLP model exhibited optimal performance in predicting soil PAEs concentrations (R²=0.8637), followed by SVR (R²=0.8132) and XGBoost (R²=0.8096). Through feature importance analysis, it was determined that hydrometeorological factors, soil moisture conditions, and nutritional characteristics were the key factors controlling PAEs spatial distribution. Furthermore, non-linear effect analysis elucidated significant synergistic interactions among these environmental covariates. The spatiotemporal prediction model revealed continuous declining trends in PAEs pollution levels in eastern coastal regions over the next 5-10 years, while accumulation tendencies were observed in inland provinces particularly in Guizhou. This study demonstrates the effectiveness and advantages of machine learning in predicting soil PAEs-pollution, providing a new perspective for pollutant risk assessment and management in the era of environmental big data.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"71 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

While manure aids in pollution control and soil fertilization, its impact on Tl bioavailability in soil remains incompletely understood. This study explored the physiological changes and Tl accumulation in Capsicum annuum under combined pollution stress and application of livestock and poultry manure near the Lanmuchang mining area. The results showed that chicken manure promoted Tl accumulation in Capsicum annuum, whereas pig and cattle manure inhibited it, with pig manure exhibiting the strongest inhibitory effect. Both pig and cattle manure reduced the transpiration rate of Capsicum annuum, which decreased the driving force for Tl transport to the plant's upper parts. Additionally, manure increased organic acid secretion in Capsicum annuum roots and decreased soil Eh. This led to a reduction in Tl3+ to the more stable Tl+, which decreased the content of exchangeable Tl form and its activity. Pig manure significantly reduced Tl content in stems, leaves, and fruits by increasing the area of the Casparian bands in Capsicum annuum roots, which hindered Tl accumulation. In contrast, chicken manure had the opposite effect. The findings of this study provide important theoretical support for scientifically guiding agricultural production safety in areas contaminated with the heavy metal Tl.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"57 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Particles from two pads were analyzed utilizing the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) brake cycle. Geometric mean diameters for both pads were found with a bimodal distribution in the ultrafine range. PM10 emission factors of 15.1 ± 0.1 mg/km and 16.3 ± 0.4 mg/km were measured, which is 2.15 and 2.32 times higher than upcoming maximum permitted emission factor of 7 mg/km. On average 54.9% and 58.1% of PM10 was emitted as iron, with a wide variety of Fe concentrations between 43 – 75% by mass found in individual particles. Other heavy metals, such as Cu, Cr, Mn and Zn, were also found and a high contribution of wear from the brake disc was noticeable, based on the elemental composition. Fe emission factors calculated from the WLTP brake cycle were 8-9 times higher than previously reported values in literature, while Cu levels were significantly lower based on recent trends in brake pad formulations.
