The complexity of the subsurface contaminated by chlorinated solvents such as trichloroethylene (TCE) makes it challenging to gain a complete understanding of contamination distribution and establish a conceptual site model (CSM). High-resolution vertical contaminant concentration profiling across both the unsaturated zone and the saturated aquifer is desirable for mapping the distribution of contamination

Effect of PM2.5 exposure on adhesion molecules and systemic nitric oxide in healthy adults: The role of metals, PAHs, and oxidative potential Chemosphere (IF 8.8) Pub Date : 2024-03-08 Danian Kahe, Zahra Sabeti, Parvin Sarbakhsh, Mohammad Shakerkhatibi, Akbar Gholampour, Gholamreza Goudarzi, Jabraeil Sharbafi, Saeed Dastgiri, Ahmad Separham, Ensiyeh Seyedrezazadeh
Since there is limited evidence on the impact of PM content on cardiovascular biomarkers, we conducted a cross-sectional study on 89 healthy adults from October 12 to November 21, 2021. We measured daily PM in two distinct regions during different time windows: a high-traffic urban area and an industrial suburb. The concentrations of metals, PAHs, and oxidative potential (OP) were determined using

Generation of 3-aminopropanamide and its cluster formation with nucleation precursors- a theoretical exploration Chemosphere (IF 8.8) Pub Date : 2024-03-08 J. Aswathi, Deepa Janardanan
Aminoamides are formed in the atmospheric environments by the auto-oxidation of the parent diamines. In this work, the oxidation chemistry of diamine (1,3-Diaminopropane, Dap) to the amino amide (3- aminopropanamide, 3-APA) and its new particle formation potential with small atmospheric molecules such as NH (A), HO (W) and HSO (SA) are theoretically investigated using the M062X/6–311++G** theory. The

Evaluating the impact of polycyclic aromatic hydrocarbon bioaccumulation in adipose tissue of obese women Chemosphere (IF 8.8) Pub Date : 2024-03-08 Sara Sousa, Paula Paíga, Diogo Pestana, Gil Faria, Cristina Delerue-Matos, Maria João Ramalhosa, Conceição Calhau, Valentina Fernandes Domingues
Polycyclic aromatic hydrocarbons (PAHs) are widespread across the environment and humans are unavoidably and constantly exposed to them. As lipophilic contaminants, these substances tend to accumulate in fatty tissues as adipose tissue and exposure to these endocrine disruptors has been associated with severe health hazards including prevalence and incidence of obesity. Previous studies have shown

Microplastics affect membrane biofouling and microbial communities during gravity-driven membrane filtration of primary wastewater Chemosphere (IF 8.8) Pub Date : 2024-03-08 Selina Hube, Stefanie Veronelli, Tian Li, Michael Burkhardt, Sigurður Brynjólfsson, Bing Wu
Recently, gravity-driven membrane (GDM) filtration has been adopted as an alternative solution for decentralized wastewater treatment due to easy installation and maintenance, reduced energy and operation cost, and low global warming impact. This study investigated the influence of microplastic size (0.5–0.8 μm and 40–48 μm) and amount (0.1 and 0.2 g/L) on the membrane performance and microbial community

Transcriptomic and biochemical analysis of metabolic remodeling in Bacillus subtilis MSC4 under Benzo[a]pyrene stress Chemosphere (IF 8.8) Pub Date : 2024-03-08 Rui Chen, Na Liu, Yuan Ren, Tangbing Cui
Polyaromatic benzo[]pyrene (B[]P) is a toxic carcinogenic environmental pollutant, and the use of microorganisms to remediate B[]P contamination is considered to be one of the most effective strategies. However, there is still a gap in studying the metabolic remodeling of microorganisms under B[]P stress. In this study, our systematically investigated the effects of B[]P on the metabolism of MSC4 based

Oxidative stress and neurotoxicity induced by exposure to settleable atmospheric particulate matter in bullfrog tadpoles, Aquarana catesbeiana, (Shaw, 1802) Chemosphere (IF 8.8) Pub Date : 2024-03-08 Isabela Ferreira Fernandes, Gabriel Hiroshi Fujiwara, Heidi Samantha Moraes Utsunomiya, Iara Costa Souza, Diana Amaral Monteiro, Magdalena Victoria Monferrán, Daniel Alberto Wunderlin, Marisa Narciso Fernandes, Cleoni dos Santos Carvalho
Bullfrog tadpoles, were exposed to settleable particulate matter (SePM), (1 g L, 96 h) and their organs were collected for analysis of metal/metalloid, oxidative stress and neurotoxicity in liver, muscle, kidney and brain. The SePM water of the exposed groups contained 18 of the 28 metals/metalloids detected in ambient particulate matter (APM). Fe and Al were those that presented the highest concentrations

Kenaf-based activated carbon: A sustainable solution for high-performance aqueous symmetric supercapacitors Chemosphere (IF 8.8) Pub Date : 2024-03-07 Thilageshwaran Subramaniam, M.N.M. Ansari, Syam G. Krishnan, Mohammad Khalid
This study presents an innovative method for synthesizing activated carbon with an exceptionally high surface area (3359 m g) using kenaf fiber-based biochar through chemical activation. The achieved specific surface area surpasses activated carbon derived from other reported fiber-based precursors. The resulting activated carbon was investigated as electrodes for supercapacitors, revealing a remarkable

The application of machine learning methods for prediction of heavy metal by activated carbons, biochars, and carbon nanotubes Chemosphere (IF 8.8) Pub Date : 2024-03-07 Xinlong Long, Xiaoliu Huangfu, Ruixing Huang, Youheng Liang, Sisi Wu, Jingrui Wang
Carbonaceous materials are commonly used as adsorbents for heavy metals. The determination of the adsorption capacity needs time and energy, and the key factors affecting the adsorption capacity have not been determined. Therefore, a new and efficient method is needed to predict the adsorption capacity and explore the decisive factors in the adsorption process. In this study, three tree-based machine
