The objective of this work is to investigate for the first time the contamination of raw wool with endocrine disruptor compounds - bisphenol A (BPA) and parabens (PBs), as well as to conduct the first biomonitoring study on long-term sheep exposure to these substances. The levels of BPA, methylparaben (MeP), ethylparaben (EtP), propylparaben (PrP) and butylparaben (BuP) were evaluated in wool samples (n = 100) from Kyrgyzstan and Poland using liquid chromatography-tandem mass spectrometry method. The highest levels were noted for BPA (range: 46.9–502 ng/g, mean 132 ± 70.5 ng/g) and MeP (range: 3.4 ng/g–71.1 ng/g, mean 19.9 ± 13.8 ng/g). Lower levels were found for EtP (range: <method quantification level (MQL) – 3.9 ng/g, mean 1.3 ± 0.7 ng/g), and levels of PrP and BuP did not exceed the MQL level in any sample. Differences in BPA, MeP and EtP levels between animals from Kyrgyzstan and Poland were noted. Some differences were also found between animals from places located close to each other in the same country. The results indicate that sheep are subject to long-term exposure to BPA and PBs, which depends on the local factors and likely negatively affect the animal's health status. This study highlights for the first time that raw natural sheep wool may be contaminated with BPA and PBs during the animal's life and, therefore, may be a potential source of human exposure to these substances.

Low-cost air pollution sensors have emerged as promising tools for monitoring air quality with high temporal and spatial resolution, especially in suburban areas of developed countries that are transitioning towards urbanization where air quality can vary significantly. The motivation for this research is to develop affordable, portable air quality sensors for suburban areas with limited access to expensive traditional monitoring equipment. This study utilized the Compact and Useful PM Instrument with gas sensors (CUPI-G), a low-cost device designed to monitor PM, CO, NO, NO, and O (from which O was calculated). The high temporal resolution data in Kyoto, Japan, averaged over 31 s, revealed seasonal variations in pollutant levels. O and CO concentrations were highest in summer, at 29.28 ppb and 95.33 ppb, respectively, and lowest in autumn, with values of 20.03 ppb for O and 81.18 ppb for CO. Conversely, PM levels were lowest in summer (4.95 μg/m) and highest in autumn (5.08 μg/m). Nearly a month of spatial analysis in three different areas (defined as residential, road, and educational) showed PM concentrations were highest in residential areas, averaging hourly 21.53 μg/m, while CO and O levels were elevated near roadways, with concentrations of 188.02 ppb, and 46.62 ppb, respectively. This research innovatively employed low-cost sensor technology to deliver high-resolution air quality data and demonstrated that wind speed and direction along with temperature were significant factors contributing to suburban air pollution, providing insights into potential pollution sources, and meteorological risk factors for elevated pollution levels.

This study implements a probabilistic framework that a) involves the generation of realizations of the criteria weights by sampling methods that model the structural dependence of multicriteria correlated data, b) evaluates the similarity of the simulated data with respect to the original dataset, and c) uses these realizations to estimate the spatial distribution of the statistical metrics of flood susceptibility, and quantifies the uncertainties that are propagated from the simulated weights to the susceptibility levels. Seven criteria have been selected according to the literature, namely, terrain elevation, slope, flow accumulation, rainfall intensity, distance from the drainage network, land use/land cover and soil. The results reveal that copula-based samples exhibit a superior ability to capture the dependence among strongly correlated criteria, whereas the simulated data based on principal component analysis (PCA) achieve better agreement in terms of the standard deviation. Consequently, copula-based samples of weighting coefficients are used to assess flood susceptibility in Cyprus via multicriteria decision analysis (MCDA). The results revealed that 50 % of the study area is classified as either highly susceptible or very highly susceptible to flooding, with the majority of these regions being present in the southern and southeastern parts of the study area. With respect to the validation dataset, the known flood-prone areas are classified as having either “Very High” (12–14 %) or “High” (> 7880 %) probabilities of flood occurrence. The proposed probabilistic framework can be directly applied in other biogeographical regions and geological contexts, depending on the characteristics of the study area.

Heavy metal concentration in pregnant women affects neurocognitive and behavioral development of their infants and children. The majority of existing research focusing on pregnant women's heavy metal concentration has considered individual environmental factor. In this study, we aim to comprehensively consider lifestyle, food, and environmental factors to determine the most influential factor affecting heavy metal concentration in pregnant women. The Ko-CHENS (Korean CHildren health and ENvironmental Study) is a nationwide prospective birth cohort study in South Korea enrolling pregnant women from 2015 to 2020. A total of 5458 eligible pregnant women were included in this study, and 897 variables were included in questionnaire comprising: maternal general information, indoor and living environment, dietary habits, health behavior, exposure to chemicals. Lead, cadmium and mercury concentration on blood were measured in early, late pregnancy and in cord blood at birth. Variables that might be related to heavy metal concentrations were included in machine learning models. Random forest and XGBoost machine learning models were conducted for predictions. Both models had similar but better performance than multiple linear regression. Kimchi (β = 1.55), seaweed (β = 0.40), fatty fish (β = 1.55), intakes respectively affected lead, cadmium, and mercury exposure through early, late pregnancy and cord blood.

Ozone (O₃) precursors controls have reduced peak episodes in the UK, yet some regions still exceed the 50 ppbv (8-h) limit under certain meteorological conditions. This study uses O₃-tagging within WRF-Chem to quantify NOₓ contributions to near-surface O₃ across the East of England during a short heatwave (30 June–5 July 2015), where O₃ peaked at 116 ppbv. Despite underestimating peak O₃, the model effectively captures the episode's evolution and spatial extent (MB: −2 ppbv, r: 0.78), depicting O₃ increases on the hottest days and their decline. During the peak O₃ event, Western Europe contributed ∼60 % of daily mean O₃, while domestic NOₓ emissions accounted for only ∼4.6 %. South-easterly winds transported O₃ and precursors from BENELUX, France, Germany, the North Sea, and the English Channel. Near-surface wind convergence (−0.00002 s−1) with weaker westerlies redirected domestic O₃ to the central UK, intensifying continental influence. Conversely, south-south-westerly flows amplified domestic O₃ contributions.
Analysis of the processes contributing to O₃ build-up highlights that transboundary transport played a significant role during the peak event. Boundary layer growth contributed by entraining O₃-rich air (up to 10.3 ppb h−1 across the boundary layer top), along with precursors from the residual layer, facilitating their downward mixing to surface levels. This process set the stage for in-situ photochemical O₃ production, which peaked at midday, contributing to a total daily O₃ production of 42 ppbv on average across the region. Our findings underscore the necessity of coordinated international efforts to manage transboundary pollution, alongside targeted local measures to reduce O₃ precursor emissions.

Assessing the species ecological responses to ongoing climate change is a critical challenge in environmental science. Rising temperatures, particularly in winter, are altering the distribution patterns of many species, including the pine processionary moth (PPM), Thaumetopoea pityocampa (Denis & Schiffermüller, 1775). This Mediterranean species, a significant defoliator of conifers, is expanding its range northward as winter temperatures increase. The larvae of PPM also pose serious public health risks due to their ability to induce allergic reactions in humans, pets, and livestock. To better understand these ecological shifts, we calibrated three distribution models (Bayesian Additive Regression Trees, Boosted Regression Trees, and Random Forest) based on historical and modern occurrence data compiling of 1769 points, and assessed climate suitability under historical, current and future conditions. Our results show that winter minimum temperatures, summer maximum temperatures, and solar radiation significantly influence the life cycle, and shape the geographical distribution of PPM. Under current conditions, PPM could extend its range further north, but its limited flight capabilities hinder its ability to keep up with the pace of climate change. Future projections suggest continued northward expansion, although solar radiation is expected to limit the northernmost range of PPM. Certain host tree species of PPM are frequently used as ornamental plants, particularly in urban areas, which makes the careful selection of these species a potentially valuable tool for management. Our findings identify regions that are likely to become suitable for PPM colonization, where proactive measures could be implemented.

It has been assumed and widely reported that arsenic (As) and antimony (Sb) share some similarities but also exhibit significant differences in their geochemical behaviors. Their environmental fates are generally controlled by iron (Fe) oxides and aluminum (Al) oxides. The mechanistic differences in their interactions, especially under dynamic environmental conditions, remain poorly understood, which hinders the development and implementation of effective pollution prevention and control measures. Therefore, this review focuses on the processes and mechanisms of interactions between As/Sb and Fe oxides/Al oxides. Antimony exhibits a higher susceptibility to oxidation than As due to its larger atomic radius and lower electronegativity. The property is an important basis for explaining the differences in their interactions in the environment. To obtain a clearer understanding of interactions, a detailed adsorption theory (charge distribution multi-site ion complexation) for the Fe oxides and Al oxides and three primary adsorption mechanisms (electrostatic adsorption, chemical adsorption, and coprecipitation) were explored. Furthermore, the effects of various factors (pH, redox, surface coverage, competing ions, and types of Fe oxides and Al oxides) on the adsorption efficiency were evaluated. We discussed the mechanisms and efficiency of Sb and As adsorption on Fe oxides and Al oxides, and the differences in Sb and As adsorption for various valence states. To efficiently control Sb and As pollution, some differences between Sb and As need to be taken into account.

To efficiently control Sb and As pollution, some differences between Sb and As need to be taken into account.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"979 ","pages":"Article 179423"},"PeriodicalIF":8.2,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143859588","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 study presents a land retirement framework that retires the least profitable portion of a field for conservation landcover. Our approach incorporates heterogeneity in optimal input use and profit within a field as well as impacts on crop insurance expenditures. Our approach also incorporates the potential for edge effects and changes in machinery overhead costs. Using on-farm precision experiment data from a midwestern corn field as a case study, we test our framework and compare the profit-maximizing land retirement strategy under alternative crop insurance approaches for partial-field land retirement. In our case study, optimal land retirement increases per-acre profit by $14.27, $27.95, or $32.21/acre in the no insurance, constant insurance, and adjusted insurance cases, respectively. Our general model shows that including crop insurance expenditures should increase the optimal amount of land in retirement (conservation), but the magnitude of the effect depends on the yield and profit heterogeneity within a field. In the most profitable land retirement strategy for our case study data, including crop insurance expenditures increases optimal land retirement by 3.4 %. Incorporating adjustments to average yield in crop insurance premiums generates 2.89 % ($4.26/acre) more profit compared to an estimation that ignores the impact of partial-field land retirement on yield.

Located within the Great Barrier Reef Catchment Area (GBRCA), the Herbert River Floodplain is designated as an area of nationally important wetlands. Furthermore, these wetlands provide a range of critical ecosystem services which protect the Great Barrier Reef World Heritage area ecosystem from land-based effects including agricultural runoff. The surrounding intensive agricultural land use puts these wetlands at risk of excessive loading of pesticides, which may result in species decline, loss of value and reduced function of ecosystem services. The aim of this study is to investigate the combined risk from the co-occurrence of pesticides in wetlands of the Herbert River Floodplain. Waters of five freshwater wetlands were monitored for 55 pesticides using a combination of grab and passive sampling techniques between February 2021 and March 2023. The combined mixture toxicity for up to 19 commonly detected pesticide active ingredients (PAIs) was estimated using the pesticide risk metric (PRM) model, calculated as the combined percentage of species affected (PAF). Thirty-six pesticides were detected in waters across five wetlands, eight of which exceeded regulatory guidelines at least once. Site-specific species protection goals were exceeded at least once at four of the five studied wetlands. Average monthly PAF (from passive sampling) was found to be increased during the wet season, though no increase in instantaneous PAF (from grab sampling) was detected in the wet season. Our findings indicate wetlands of the broader GBRCA are likely to be at risk due to pesticide exposure, and that this risk occurs during both wet and dry seasons. Risk periods in wetlands are not consistent with those previously observed in nearby rivers and creeks and should be monitored accordingly.
