While trace metals and legacy pollutants have been well documented, the extent of wildlife exposure to emerging contaminants has received little attention, in terrestrial mammals. Concentrations of trace elements (Ag, Al, As, Cd, Co, Cr, Cu, Fe, Mn, Pb and Zn) and 48 organic pollutants (Polychlorinated Biphenyls: PCBs, Organochlorine Pesticides: OCPs, Polycyclic Aromatic Hydrocarbons: PAHs, phthalates and pyrethroid pesticides) were measured in tissues of European hedgehogs (<em>Erinaceus europaeus</em>) in southern Sweden. Road kills and carcasses collected in 2021 and 2022 by citizen science participants were used to characterize the level, tissue distribution and composition of mixtures in liver, spines and teeth samples. Phthalate diesters and PCBs were the most prevalent compounds in liver samples, with mean concentrations (± SD) of 1,090 ± 681 and 284 ± 231 ng g^-1 of dry weight, respectively. Bioaccumulation patterns were observed for some organochlorine compounds but were hampered by the small sample size. Trace element concentrations and tissue distribution were strikingly equivalent between tissue type and age-classes (juveniles and adults) of hedgehogs, except for a handful of elements (<em>e.g.,</em> Pb, Al, As), but contamination profiles differed between habitat types. While no adverse health effects are expected to occur from the body burdens measured for most of the target analytes, concerns might be expressed for the exposure to PCBs, phthalates and some non-essential trace metals (<em>e.g.,</em> lead &gt; 15 μg g^-1 dw), which were found at levels above or approximating toxic thresholds in mammal tissues. The present study demonstrates the suitability of road kills as an alternative approach for environmental monitoring and the relevance of nondestructive biomonitoring to evaluate endogenous exposure in hedgehogs and possibly other terrestrial mammals and humans.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"23 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142925154","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}

The serial truncation mutations of the C-terminal tail increase the catalytic efficiency of truncated proteins against the 2,3-dihydroxybiphenyl (2,3-DHB). RW1-4CC lose its 50% of activity at 60°C, with its optimum temperature at 15°C, whereas the truncated proteins were found to be more stable at extended temperature range, i.e., both RW1-4CC-A and RW1-4CC-B retained 50% of their activity at 75°C, with their temperature optima at 55°C and 65°C, respectively. The molecular docking studies further confirmed the high binding affinity of truncated proteins for the 2,3-DHB than catechol. The molecular modeling analysis revealed the difference in iron-binding and substrate interacting environment of RW1-4CC and its truncated proteins. The efficiency of purified RW1-4CC to detect catechol was evaluated using a gold screen-printed electrode by cyclic voltammetry.

Radon exposure is the leading cause of lung cancer among non-smokers in the US. Radon infiltrates homes through soil and building foundations. This study advances methodologies for assessing residential radon exposure by leveraging a comprehensive dataset of 126,382 short-term (2-7 days) radon test results collected across North Carolina from 2010 to 2020. Employing a combination of linear regression and advanced machine learning techniques, including random forest models.Analysis through linear regression, linear mixed-effects models (LME), and generalized additive models (GAM) using the first-time tested radon levels reveals that elevation, proximity to geological faults, and soil moisture are pivotal in determining radon concentration. Specifically, elevation consistently shows a positive relationship with radon levels across models (linear regression: β=0.12, p&lt;0.001; LME: β=0.17, p&lt;0.001; GAM: β=0.11, p&lt;0.001). Conversely, the distance to geological faults negatively correlates with radon concentration (linear regression: β=-0.11, p&lt;0.001; LME: β=-0.06, p&lt;0.001; GAM: β=-0.07, p&lt;0.001), indicating lower radon levels further from faults.Using the random forest model, our study identifies the most influential environmental predictors of first-time tested radon levels. Elevation is the most influential variable, followed by median instantaneous surface pressure and soil moisture in the upper 10 cm layer, illustrating the significant role of geological and immediate surface conditions. Additional important factors include precipitation, mean temperature, and deeper soil moisture levels (40-200 cm), which underscores the influence of climate on radon variability. Root zone soil moisture and the Normalized Difference Vegetation Index (NDVI) also contribute to predicting radon levels, reflecting the importance of soil and vegetation dynamics in radon emanation. By integrating multiple statistical models, this research provides a nuanced understanding of the predictors of radon concentration, enhancing predictive accuracy and reliability.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"116 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142924768","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}

This study investigates the joint effect of prenatal exposure to cadmium (Cd), nickel (Ni), mercury (Hg), and lead (Pb) on infant neurodevelopment using various statistical approaches. The study included 400 mother-infant pairs. Heavy metal levels were measured in maternal urine samples at the 12th week of gestation, and infant neurodevelopment at 40 days was evaluated by the Bayley Scales of Infant and Toddler Development. Generalized Additive Models (GAM), Multivariable Linear Regression (MLR) with restricted cubic spline (RCS), Bayesian Kernel Machine Regression (BKMR), and Weighted Quantile Sum (WQS) regression were applied to explore the associations between heavy metal exposure and neurodevelopmental outcomes. GAM revealed a significant linear relationship for Cd with cognitive scale (p = 0.045) and expressive language (p = 0.043). MLR confirmed that Cd was negatively associated with both cognitive scale (β = -1.47, p = 0.044) and expressive language (β = -0.32, p = 0.019) and RCS presented a non-linear association between Pb and language scale (p = 0.001). BKMR suggested a negative but non-significant association with most outcomes. WQS indicated a significant adverse effect of metal mixture on expressive language (β = -0.26, 95% CI = -0.44, -0.07), identifying Cd and Ni as the primary contributors.

This study investigated the physicochemical stability, trophic transfer, and toxic effects of citrate-coated AgNPs in a freshwater food chain including the diatom <em>Cyclotella meneghiniana</em> and the gastropod <em>Lymnaea stagnalis</em>. AgNPs remained stable in the exposure medium, with a minimal dissolution (&lt;0.06%) after 24 h, indicating that particulate forms dominated during exposure. AgNPs inhibited the growth of <em>C. meneghiniana</em> without significantly affecting chlorophyll-a content or reactive oxygen species (ROS) production. Scanning electron microscopy revealed extracellular polymeric substance (EPS) secretion, which likely formed eco-coronas, reducing AgNPs bioavailability and oxidative damage. However, trace element analysis showed significant depletion of iron, manganese, and nickel, indicating early metabolic stress and redistribution of essential metals to support antioxidant defenses. In <em>L. stagnalis</em>, toxicokinetic analysis showed distinct patterns of Ag uptake and depuration across exposure routes. Waterborne and foodborne exposure resulted in similar and higher Ag accumulation compared to the combined group. Waterborne exposure showed the highest non-eliminable fraction and a bioconcentration factor (BCF) &gt; 1, indicating efficient uptake and retention. Foodborne exposure exhibited a biomagnification factor (BMF) &gt; 1, despite efficient elimination. Combined exposure had the highest depuration rate, with BCF &gt; 1 and BMF &lt; 1, reflecting reduced trophic transfer potential. Oxidative stress in <em>L. stagnalis</em> was highest during combined exposure, with increased ROS in hemolymph during uptake. Foodborne exposure caused prolonged immune stress, evidenced by elevated total antioxidant capacity (TAC) and protein levels. In the hepatopancreas, foodborne exposure during depuration led to increased lipid peroxidation and TAC, indicating oxidative and metabolic challenges specific to dietary exposure. These results highlighted the complex interactions of AgNPs with primary producers and consumers in freshwater ecosystems, emphasizing the need for multi-route assessments in nanoparticle risk evaluations.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"72 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142924730","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}

Fungi, as eco-friendly alternatives to chemical treatments, have the potential to reduce HM bioavailability in contaminated soils while promoting plant growth. However, current fungal remediation methods face limitations in efficiency, long-term effectiveness, and the ability to address combined contamination, particularly with naturally occurring strains. Herein, we developed a <em>Trichoderma reesei</em>-Laccase (LAC)-Biochar coupling system (TLBS), based on the structural and electrostatic analyses of LAC’s metal-chelated active site (T1 Cu), for the sustainable remediation of combined pollutants, including HMs. In the TLBS, genetically engineered <em>T. reesei</em> produces a mutated LAC with enhanced binding capability for HMs (Ni and Cd). The TLBS enables high-efficiency remediation through three steps. First, lignin-derived biochar serves as both a supportive carrier and an inducer, initiating LAC expression. Second, natural mediators are released due to the interaction between biochar and <em>T. reesei</em>, and LAC is activated by environmental HMs and natural mediators. Finally, TLBS achieved significant reductions in the available concentrations of Ni (93.63%) and Cd (89.68%) and efficiently remediated multiple organic pollutants (71.41–96.79%), including antibiotics and pesticides. Furthermore, the synergistic interaction among TLBS components ensures long-term remediation effects in environments rich in agricultural biomass, making it ideal for eco-friendly farming practices. This in situ amendment strategy, utilizing only green, biodegradable lignocellulosic wastes and environmentally friendly fungi, offers new pathways for the sustainable management of combined contamination and the improvement of human health.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"4 3 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142924770","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}

In order to contribute to the understanding of aerosol dynamics during dental operation and efficiently mitigate their dispersion and deposition through appropriate ventilation, 3D numerical simulations and full-scale experimental measurements were performed in this study. The indoor airflow distribution and dynamic aerosol behaviors observed under three optimized ventilation schemes (Scenario I-III) were compared with those observed under the current ventilation system. Qualitative analysis was performed together with quantitative examination using the air age, air change efficiency, contaminant removal effectiveness, and deposition ratio. It is demonstrated that the ventilation currently in use is unable to effectively discharge aerosols, resulting in most of them depositing on surfaces routinely accessed by dental workers. The pronounced air mixing effect induced by the design of Scenario I facilitates the rapid dispersion of aerosols throughout the clinic, impeding the efficient removal via the outlet. Moreover, the effective elimination of indoor aerosols is only attainable by implementing high ventilation rates in Scenario II.

Therefore, it is of practical significance to study air pollution exposure characteristics of different age groups in the context of accelerating aging in China. In this study, we used the number of people and air pollutant concentration data at the township-level scale (the smallest administrative unit in China) to calculate population-weighted PM_2.5 concentration exposure (PM_2.5 PWE) values of different age groups in the Beijing-Tianjin-Hebei (BTH) region, quantified the pollution exposure differences among different groups, and analyzed the spatiotemporal changes in such differences and their driving factors. Although air quality has improved, these improvements have not been equally distributed across all age groups, leading to intensified disparities in air pollution exposure. Specifically, the elderly were exposed to lower PM_2.5 concentrations in 2010 and 2020, and the working age group had the highest annual PM_2.5 PWE in 2010 and the largest reduction in PM_2.5 PWE between 2010 and 2020. The PM_2.5 PWE of the children group was higher in 2020. The exposure disparities among groups increased in 2020 compared to 2010, and the exposure disparities and their variations were related to the administrative area, rural employment, per capita disposable income, NVDI, wind speed, and temperature.
