Since Europe's 2018 neonicotinoid ban on outdoor use of clothianidin, imidacloprid, and thiamethoxam, there has been growing political, scientific, and public interest in further understanding the impact of neonicotinoids on bees and the environment. Here, we assessed the trends in pesticide use in New Zealand, with a particular focus on neonicotinoids, to aid discussion on their use and associated risks. Obtaining data on annual trends in pesticide quantities is challenging, as there is no central collection of pesticide data across the agrichemical or regulatory sectors in New Zealand. Consequently, the true scale and frequency of pesticide usage, including neonicotinoids, remain largely unknown. The difference in neonicotinoid use patterns between New Zealand, where 45 % of forage brassicas (annual planting) and pastures (infrequent planting) are grown from neonicotinoid-treated seeds, and northern hemisphere countries, where 56 % to over 90 % of annual food crops rely on neonicotinoid-treated seeds, indicates a lower overall neonicotinoid use in New Zealand. This difference underscores the need for region-specific approaches to pesticide management and regulation. Although residues can persist and migrate in the soil, current regulations only consider the risk of foliar spray to protect honey bees, overlooking the potential risks to native bees, which primarily live underground, as well as wider lethal and sublethal impacts of residues on non-target organisms. The lack of publicly accessible pesticide data limits scientific research on non-target and environmental effects, and the absence of readily available substitutes for neonicotinoids is the key challenge to be overcome in order to better manage the impact of these pesticides on New Zealand ecosystems.

Wastewater-based surveillance (WBS) of SARS-CoV-2 is increasingly recognized as a valuable complement to clinical reporting for estimating COVID-19 infection rates. This acceptance stems from the strong correlation found between wastewater and clinical case data during the early stages of the pandemic. However, the cessation of COVID-19 restrictions, changes in clinical testing requirements by late 2021, and the widespread use of take-home antigen tests have diminished the reliability and volume of clinically reported case counts. This study explores the dynamics between clinical cases and wastewater-based results in a period of transition, focusing on student residential areas within a university campus. We analyzed wastewater from 13 sub-sewersheds, serving populations of 300 to 4000 individuals, three times weekly from December 2021 to June 2022. The analysis revealed two COVID-19 spikes in wastewater data during this time, whereas clinical reports indicated at most a single surge in infections across most communities. Further, in the first infection surge, clinical data plateaued sooner than wastewater trends and, in the second surge, either lagged or were completely absent. Correlations between wastewater SARS-CoV-2 concentrations and the 3-day rolling average of clinical cases were weak in smaller communities (≤1000 people) but improved with larger community sizes (>1000 people). Normalization with PMMoV did not enhance these correlations. Given the challenges in executing widespread and accurate mass clinical testing, our findings advocate for the efficacy of WBS data in reliably forecasting infection surges, even in less populous settings, thereby facilitating swift, informed public health interventions.

Pesticides provide vital protection against insect pests and the diseases they vector but are simultaneously implicated in the drastic worldwide decline of beneficial insect populations. Convincing evidence suggests that even sublethal pesticide exposure has detrimental effects on both individual- and colony-level traits, but the mechanisms mediating these effects remained poorly understood. Here, we use bumble bees to examine how sublethal exposure to pesticides affects mating, a key life history event shared by nearly all insects, and whether these impacts are mediated via impaired sexual communication. In insects, mate location and copulation are primarily regulated through chemical signals and rely on both the production and perception of semiochemicals. We show through behavioral bioassays that mating success is reduced in bumble bee gynes after exposure to field-relevant sublethal doses of imidacloprid, and that this effect is likely mediated through a disruption of both the production and perception of semiochemicals. Semiochemical production was altered in gyne and male cuticular hydrocarbons (CHCs), but not in exocrine glands where sex pheromones are presumably produced (i.e., gyne mandibular glands and male labial glands). Male responsiveness to gyne mandibular gland secretion was reduced, but not the queen responsiveness to the male labial secretion. In addition, pesticide exposure reduced queen fat body lipid stores and male sperm quality. Overall, the exposure to imidacloprid affected the fitness and CHCs of both sexes and the antennal responses of males to gynes. Together, our findings identify disruption of chemical signaling as the mechanism through which sublethal pesticide exposure reduces mating success.

杀虫剂为抵御害虫及其传播的疾病提供了重要保护，但同时也与全世界益虫数量的急剧减少有关。令人信服的证据表明，即使是亚致死剂量的杀虫剂暴露也会对个体和群体的性状产生有害影响，但人们对这些影响的中介机制仍然知之甚少。在这里，我们利用熊蜂来研究亚致死农药暴露如何影响交配（几乎所有昆虫都有的一个关键生活史事件），以及这些影响是否通过受损的性交流来介导。在昆虫中，配偶位置和交配主要通过化学信号来调节，并依赖于半化学物质的产生和感知。我们通过行为生物测定表明，大黄蜂雌蜂在暴露于田间相关亚致死剂量的吡虫啉后，交配成功率会降低，而这种影响很可能是通过干扰半化学物质的产生和感知而介导的。阴性和雄性角质碳氢化合物（CHC）中的半化学物质的产生发生了变化，但可能产生性信息素的外分泌腺（即阴性下颌腺和雄性唇腺）中的半化学物质的产生没有发生变化。雄性对下颌阴腺分泌物的反应降低了，但雌性对雄性唇腺分泌物的反应却没有降低。此外，接触杀虫剂还降低了蜂王体内脂质的储存量和雄性精子的质量。总之，暴露于吡虫啉会影响雌雄两性的体能和CHC，以及雄性对雌性的触角反应。总之，我们的研究结果表明，化学信号的干扰是亚致死农药暴露降低交配成功率的机制。

This paper analyses the concentration of particulate matter PM_2.5 from monitors deployed, by the Schools' Air Quality Monitoring for Health and Education Initiative (SAMHE), to 490 schools across the United Kingdom throughout the academic year 2023–2024. The data shows that the PM_2.5 concentration in schools is closely correlated to the ambient outdoor PM_2.5 concentrations. Whilst the evidence gathered indicates that sources of PM_2.5 within schools contribute to the concentrations, it is shown that outdoor sources are the dominant signature within the PM_2.5 concentration measurements made indoors. Moreover, over the academic year, outdoor PM_2.5 events — periods of elevated outdoor PM_2.5 concentration — are shown to account for approximately 41% of the total potential exposure, whilst occurring on only around 13% of schooldays. These, and other findings presented herein, have important implications for school air quality and how air quality within schools, and beyond, is managed.

This study assesses the quality of groundwater in the Odra River Basin in Poland, focussing on environmental health risks, temporal variability, and their association with salinity indices. A new indicator, the Groundwater Safety and Availability Index (GSAI), was developed to evaluate groundwater resources by integrating health risk and resource quantity factors, providing a novel tool for ranking water resources and informing environmental and administrative decision-making. Groundwater samples were collected between 2005 and 2021 and analysed in accordance with national standards. The results demonstrate an improvement in groundwater quality over time, indicated by a reduction in Health Index (HI) values, particularly in Lower Silesia, Lubusz, and Silesia. Significant correlations were found between HI and NO₃⁻ (τ-Kendall = 0.40) and arsenic (τ-Kendall = 0.55). GSAI values varied across regions, with West Pomerania showing the highest groundwater safety and availability, while Silesia had the lowest. Elevated concentrations of contaminants such as arsenic and nitrates were found to significantly impact water safety, particularly during hydrogeological droughts. These findings support the need for region-specific management strategies to ensure sustainable groundwater use and mitigate health risks, with the GSAI serving as a valuable tool for policymakers and environmental planners.

Groundwater is considered a significant source of drinking water around the world. However, the naturally occurring trace elements, mostly As, B, Fe, Mn, Cu, and Zn are proven to deteriorate the groundwater quality. This study aimed to evaluate the seasonal distribution of trace metals and

N O_{3}^{-}

in groundwater and the associated risk to human health in the coastal region of Bangladesh. The result indicated that As exceeded the WHO and BDWS limits during wet and dry seasons in several coastal districts. Despite the abundant presence of Fe throughout the entire study area, it does not present any significant health risk. But alarming conditions of Mn have been observed all over the coastal area in both seasons. Aquifers with shallow depths showed to be more contaminated than deeper ones. The spatial distribution maps showed that

N O_{3}^{-}

and Cr were found in high concentration in some similar areas during the dry season. The studied elements showed a pattern in exceeding of WHO permissible limits such as Fe > Mn > As > Cr >

N O_{3}^{-}

in wet season and Mn > Fe > As > Cr >

N O_{3}^{-}

in dry season. Therefore, high non-carcinogenic and carcinogenic risk was found among adult and children population via oral exposure. Most of the samples showed cancer risk at medium to very high. The principal component analysis observed the pollution sources, revealing that groundwater contamination in this region was mostly due to geogenic sources. This study clearly showed that the groundwater in coastal districts is heavily contaminated, which is a concerning issue. The aforementioned findings have given some clarity on the coastal region's groundwater quality state, which can be beneficial in formulating a plan safe water supply.

The Iberian Peninsula is a water-scarce region that is increasingly reliant on groundwater. Climate change is expected to exacerbate this situation due to projected irregular precipitation patterns and frequent droughts. Here, we utilised convolutional neural networks (CNNs) to assess the direct effect of climate change on groundwater levels, using monthly meteorological data and historical groundwater levels from 3829 wells. We considered temperature and antecedent cumulative precipitation over 3, 6, 12, 18, 24, and 36 months to account for the recharge time lag between precipitation and groundwater level changes. Based on CNNs performance, 92 location-specific models were retained for further analysis, representing wells spatially distributed throughout the peninsula. The CNNs were used to assess the influence of climate change on future groundwater levels, considering an ensemble of eight combinations of general and regional climate models under the RCP4.5 and RCP8.5 scenarios. Under RCP4.5, an average annual temperature increase of 1.7 °C and a 5.2 % decrease in annual precipitation will result in approximately 15 % of wells experiencing >1-m decline between the reference period [1986–2005] and the long-term period [2080–2100]. Under RCP8.5, with a 3.8 °C increase in temperature and a 20.2 % decrease in annual precipitation between the same time periods, 40 % of wells are expected to experience a water level drop of >1 m. Notably, for 72 % of the wells, temperature is the main driver, implying that evaporation has a greater impact on groundwater levels. Effective management strategies should be implemented to limit overexploitation of groundwater reserves and improve resilience to future climate changes.

Effective management strategies should be implemented to limit overexploitation of groundwater reserves and improve resilience to future climate changes.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"970 ","pages":"Article 179009"},"PeriodicalIF":8.2,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143552714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Engineered timber can represent a great opportunity to mitigate the large impacts due to the global building sector. However, the most applied environmental assessment methodologies such a life cycle assessment (LCA) might show limited advantages when comparing the impact on climate change of buildings made of traditional materials, such as concrete and steel, and building based on engineered timber. This work proposes emergy evaluation (EME) as a complementary environmental assessment methodology. By expanding the boundaries of the assessment, EME captures input flows and related features, especially in terms of renewability, that are overlooked in LCA. LCA and EME were applied to two identically modeled buildings composed of either only traditional materials or engineered timber as their replacement. EME reveals the higher sustainability level of engineered timber compared to traditional materials in the building sector, capturing larger environmental benefits compared to LCA. Ultimately, the robustness of the results is tested through a comparative sensitivity analysis performed for three geographic scenarios, different energy use scenarios, and different transport distances.

Litter pollution, particularly from plastic waste, has escalated into a global crisis that poses substantial risks to aquatic ecosystems and human health. This comprehensive review systematically explores litter transport dynamics from terrestrial sources to marine environments, focusing on key objectives that include examining the intricate hydrodynamic processes involved in the movement of litter from land to sea. It identifies significant inland contributors to marine litter, such as rivers, urban runoff, and stormwater drainage outflows, as critical sources often overlooked in current studies. Natural factors, such as rainfall and riverine flow, and anthropogenic ones, such as urbanization and waste management practices, make litter mobilization and transport processes very complex. A key finding is that current techniques and data cannot grasp this complexity, pointing to the need for an improved holistic modeling framework. By synthesizing insights from diverse studies, the need for cross-disciplinary collaboration and robust data-sharing frameworks is highlighted to enhance model reliability and predictive capacity. Ultimately, these findings provide critical insights and guidance for environmental policymakers, researchers, and community organizers, empowering them to implement effective measures to combat litter pollution and safeguard marine habitats for future generations.

Conservation genomics is a rapidly growing subdiscipline of conservation biology that uses genome-wide information to inform management of biodiversity at all levels. Such efforts typically focus on species or systems of conservation interest, but rarely consider associated microbes. At least three major approaches have been used to study how microorganisms broadly contribute to conservation areas: (1) diversity surveys map out microbial species distribution patterns in a variety of hosts, natural environments or regions; (2) functional surveys associate microbial communities with factors of interest, such as host health, symbiotic interactions, environmental characteristics, ecosystem processes, and biological invasions; and (3) manipulative experiments examine the response of changes to microbial communities or determine the functional roles of specific microbes within hosts or communities by adding, removing, or genetically modifying microbes. In practice, multiple approaches are often applied simultaneously. The results from all three conservation genomics approaches can be used to help design practical interventions and improve management actions, some of which we highlight below. However, experimental manipulations allow for more robust causal inferences and should be the ultimate goal of future work. Here we discuss how further integration of microbial research of a host's microbiome and of free living microbes into conservation biology will be an essential advancement for conservation of charismatic organisms and ecosystem functions in light of ongoing global environmental change.
