The South Korean government has implemented an acceptance system to promote the high-quality recycling of waste. Industrial waste generators must provide “hazardous characteristics data” to recycling operators. Nonetheless, ~80% of industrial safety accidents in South Korea occur during recycling, most involving fire or explosions. Moreover, a gap in safety management exists during ‘Circular Resource’ acceptance if the target substance is not regarded as waste. In this study collected data on hazardous waste characteristics. From 62 waste generators, 72 waste samples were collected, accounting for most of the resources accepted for recycling, including waste synthetic polymers, slag, dust, waste sand, and waste foundry sand. Then, the hazardous characteristics, as stated in the Ministry of Environment notifications, were assessed. Leaching toxicity was detected in one slag sample and six dust samples. The Cd, Cu, As, Pb, Zn, Ni, Hg, F, and CN levels dissatisfied the Soil Contamination Warning Standard in 31 samples. Explosivity was not detected in any sample, whereas flammability was detected in one waste synthetic polymer sample. The results revealed 15 cases of potential flammability. Flammability is legally defined as below the criteria if the combustion speed criterion is not met. However, in the case of flame ignition, which could cause large fires and safety accidents, the relevant notification should be revised. In this study, we aimed to improve the gap between the hazardous waste management systems and industrial fields through actual measurements of hazardous characteristics. By doing so, we seek to contribute to the prevention of environmental and safety accidents. By continuously accumulating data and utilizing actual measurements, we aim to revise and enhance relevant regulations, ultimately improving the hazardous characteristics of waste management systems.
韩国政府实施了一项验收制度,以促进废物的高质量回收利用。工业废物产生者必须向回收经营者提供 "危险特性数据"。然而,韩国约 80% 的工业安全事故发生在回收过程中,其中大部分涉及火灾或爆炸。此外,如果目标物质不被视为废物,那么在 "循环资源 "接收过程中就会出现安全管理漏洞。本研究收集了有关危险废物特征的数据。从 62 个废物产生者中收集了 72 个废物样本,其中包括废合成聚合物、炉渣、粉尘、废砂和废铸造砂等大部分可接受循环利用的资源。然后,对环境部通知中规定的危险特性进行了评估。在一个炉渣样本和六个粉尘样本中检测到了浸出毒性。在 31 个样本中,镉、铜、砷、铅、锌、镍、汞、萤石和氯化萘的含量不符合土壤污染警告标准。没有在任何样本中检测到爆炸性,但在一个废弃合成聚合物样本中检测到可燃性。结果显示有 15 个样品存在潜在的易燃性。如果不符合燃烧速度标准,可燃性在法律上被定义为低于标准。但是,在火焰点燃的情况下,可能会引发大火和安全事故,因此应修订相关通知。在这项研究中,我们旨在通过对危险特性的实际测量,改善危险废物管理系统与工业领域之间的差距。通过这样做,我们力求为预防环境和安全事故做出贡献。通过不断积累数据和利用实际测量结果,我们旨在修订和完善相关法规,最终改善废物管理系统的危险特性。

A historically large percentage of the world’s population has moved to urban areas in the past few decades, causing various negative effects for the environment, such as air, noise, water, and light pollution; land degradation; and biodiversity loss. Under the current climate crisis, cities are anticipated to play an essential part in adaptation strategies to extreme atmospheric events. This study aims at developing indicators at an urban scale that can highlight adaptation progress by investigating relevant data (especially in situ) and statistics at a pan-European level in support of the EU’s strategy for adapting to the impacts of climate change. The proposed indicator, Urban Biodiversity Indicator for Trees (UBI4T), which can be derived from city tree inventories, assesses one essential component of urban biodiversity by computing the proportion of native, alien, invasive, and toxic tree species spatially across a city. According to our findings (applying the UBI4T for Amsterdam and exploring its policy potential for Barcelona), the UBI4T can offer crucial information for decision and policy makers, as well as stakeholders of a city, with the aim of conducting dedicated and effective strategic initiatives to restore, improve, and protect nature in the urban environment, thus contributing to adaptation and resilience to extreme atmospheric events in cities.
在过去几十年里,世界上很大一部分人口迁移到了城市地区,对环境造成了各种负面影响,如空气、噪音、水和光污染;土地退化;生物多样性丧失。在当前的气候危机下,预计城市将在极端大气事件的适应战略中发挥重要作用。本研究旨在通过调查泛欧层面的相关数据(尤其是实地数据)和统计资料,制定城市尺度的指标,以突出适应进展,支持欧盟适应气候变化影响的战略。拟议的指标--城市树木生物多样性指标(UBI4T)可从城市树木清单中提取,通过计算城市中本地、外来、入侵和有毒树木物种的空间比例来评估城市生物多样性的一个重要组成部分。根据我们的研究结果(将 UBI4T 应用于阿姆斯特丹,并探索其在巴塞罗那的政策潜力),UBI4T 可为决策者和政策制定者以及城市的利益相关者提供重要信息,以便采取专门、有效的战略措施来恢复、改善和保护城市环境中的自然,从而促进城市对极端大气事件的适应和抵御能力。

Rural and semi-urban areas in arid/semi-arid regions are facing severe water scarcity and a series of environmental challenges nowadays, specifically due to rapid urbanization and economic development, climate change, population growth, increasing water demand, influxes of refugees caused by war and regional political conflict, etc. To solve the emerging problems, the safe reuse of treated wastewater in agriculture can provide an additional water resource for countries with high water scarcity. The aim of this study was to investigate the treatment performance and effectiveness of small decentralized wastewater treatment (DWWT) technologies treating high-strength wastewater with concentrations far beyond the European Union testing ranges of parameters such as five-day biochemical oxygen demand (BOD5 > 500 mg/L), chemical oxygen demand (COD > 1000 mg/L), or total suspended solids (TSS > 700 mg/L). Four (4) commercially available DWWT technologies with a design capacity of 4–8 PE (population equivalent) were selected and operated with various wastewater compositions in Leipzig, Germany. The technologies were (i) the moving bed biofilm reactor (MBBR), (ii) the sequencing batch reactor (SBR), (iii) the membrane bioreactor (MBR) and (iv) the aerated vertical-flow constructed wetland (AVFCW). This study results clearly demonstrated that the EU-certified small DWWT technologies are quite capable of treating high-strength wastewater and can provide high-quality treated water for safe reuse in rural communities of arid and semi-arid regions. During operation with high-strength wastewater with a mean inflow BOD5, COD and TSS concentrations of 1532 ± 478, 2547 ± 830 and 546 ± 176 mg/L, a low mean BOD5 (<10 mg/L), COD (<70 mg/L) and TSS (<15 mg/L) in the outflow of the four systems showed removal efficiency of BOD5 (>99%), COD (>97%) and TSS (>97%), and met the maximum allowable limit value of water quality class A for reuse in agriculture according to Jordanian and Omani standard. The MBR showed almost a complete removal of Escherichia coli (E. coli) in a range of 6.1–6.9-log removal in the outflow during all three experimental phases and performed best for BOD5, COD, TSS and pathogen removal when treating high-strength wastewater if properly maintained to prevent potential fouling and clogging of the membrane. Before the final permitting process, long-term monitoring under local temperature and climatic conditions as well as guidelines based on local needs (e.g., in Jordan, Oman, etc.) should be developed to guarantee a minimum level of performance standards of such small DWWT technologies and requirements for operation and maintenance (O&M).
当前,干旱/半干旱地区的农村和半城市地区正面临着严重的水资源短缺和一系列环境挑战,特别是由于快速的城市化和经济发展、气候变化、人口增长、水资源需求增加、战争和地区政治冲突造成的难民潮等。为了解决新出现的问题,将处理过的废水安全地再用于农业,可以为缺水严重的国家提供额外的水资源。本研究的目的是调查小型分散式废水处理(DWWT)技术在处理高浓度废水时的处理性能和效果,这些废水的浓度远远超出了欧盟的测试范围,如五日生化需氧量(BOD5 > 500 mg/L)、化学需氧量(COD > 1000 mg/L)或总悬浮固体(TSS > 700 mg/L)。在德国莱比锡,选择了四 (4) 种设计处理能力为 4-8 PE(人口当量)的商用 DWWT 技术,并在不同的废水成分下进行了运行。这些技术是:(i) 移动床生物膜反应器 (MBBR)、(ii) 顺序批式反应器 (SBR)、(iii) 膜生物反应器 (MBR) 和 (iv) 曝气垂直流人工湿地 (AVFCW)。研究结果清楚地表明,经欧盟认证的小型 DWWT 技术完全有能力处理高强度废水,并能为干旱和半干旱地区的农村社区提供高质量的安全回用水。在处理高浓度废水的运行过程中,平均进水 BOD5、COD 和 TSS 浓度分别为 1532 ± 478、2547 ± 830 和 546 ± 176 mg/L,平均 BOD5(99%)、COD(>97%)和 TSS(>97%)较低,达到了约旦和阿曼标准规定的农业回用 A 类水质的最大允许限值。在所有三个实验阶段,膜生物反应器几乎完全清除了流出物中的大肠杆菌(E.coli),清除率在 6.1-6.9 个菌落之间,在处理高浓度废水时,如果维护得当,防止膜可能出现的堵塞,膜生物反应器在去除 BOD5、COD、TSS 和病原体方面表现最佳。在最终许可程序之前,应根据当地需要(如约旦、阿曼等国),制定在当地温度和气候条件下的长期监测以及指导方针,以保证此类小型 DWWT 技术的最低性能标准以及运行和维护(O&M)要求。

The Mississippi River System is of great ecological and economic importance, making it crucial to monitor contaminants within it. While nutrient pollution is well studied, there are little data on microplastics (MPs) in the Mississippi River System (MSRS), especially during drought conditions. Herein, we characterize MP pollution from seven sites across the MSRS during both flash drought and non-drought periods using FTIR microspectroscopy (µ-FTIR). Additionally, we evaluate the impact of multiple water level conditions on MP polymer composition across five time points at a single sampling site. Of all MPs identified, polyethylene terephthalate (PET, 22%), resin (17%), and polyethylene (PE, 10%) were the most abundant polymers. Average concentrations ranged from 16 to 381 MPs/L across seven sites, with no significant difference in concentration between conditions. Irregular particles were the most common morphology, with most MPs falling in the lowest size range measured (30–100 μm). Drought condition had a significant (p < 0.001) impact on polymer composition, and polymers most strongly correlated with flash drought were mostly fluoropolymers. For the single sampling site, concentrations differed, but not significantly, across the five timepoints. These results demonstrate the complex relationship between MP concentration and drought condition, and also highlight the importance of fully characterizing MPs in environmental studies.
密西西比河系统具有重要的生态和经济意义,因此对其中的污染物进行监测至关重要。虽然对营养物污染的研究很深入,但有关密西西比河水系(MSRS)中微塑料(MPs)的数据却很少,尤其是在干旱条件下。在本文中,我们使用傅立叶变换红外微光谱(µ-FTIR)分析了密西西比河水系七个地点在干旱和非干旱期间的微塑料污染特征。此外,我们还评估了单个采样点五个时间点的多种水位条件对 MP 聚合物组成的影响。在确定的所有 MP 中,聚对苯二甲酸乙二醇酯(PET,22%)、树脂(17%)和聚乙烯(PE,10%)是含量最高的聚合物。七个地点的平均浓度介于 16 至 381 MPs/L 之间,不同条件下的浓度差异不大。不规则颗粒是最常见的形态,大多数 MP 属于所测得的最小粒径范围(30-100 μm)。干旱条件对聚合物成分有显著影响(p < 0.001),与闪旱关系最密切的聚合物主要是含氟聚合物。就单个采样点而言,五个时间点的浓度存在差异,但不明显。这些结果表明了 MP 浓度与干旱状况之间的复杂关系,同时也强调了在环境研究中全面描述 MP 特性的重要性。

The European Union’s Green Deal concept prioritizes the installation of photovoltaic and wind turbine systems, with the aim of significantly reducing greenhouse gas emissions and expanding the use of renewable energy. The inclusion of metals/metaloids such as Cd, Pb, Ni, and As to PV panels may be a matter of concern because they may provoke numerous negative environmental effects, especially after decommissioning. Although the release of Pb and Cd from solar panels is generally low, these releases may increase, posing long-term harm. Cd and Pb, if only released from solar panels, can enter the environment, including soil and water, posing a significant risk to human health and ecosystems. Cd, in particular, can have profound and lasting negative impacts on animals and humans, affecting cellular responses, enzyme operations, and immune system functionality. Pb exposure, in turn, can induce oxidative stress and neurotoxicity, disrupt ion regulatory pathways, and impair immune function. Despite efforts to reduce the release of toxic metals from PV panels, controlling their disposal and avoiding environmental contamination remains challenging. Discovering substitute materials for PV panel manufacture, implementing enhanced recycling procedures, performing bioremediation, and enforcing stronger restrictions are among the strategies to mitigate environmental concerns.
欧盟的 "绿色交易 "概念优先考虑安装光伏和风力涡轮机系统,目的是大幅减少温室气体排放和扩大可再生能源的使用。在光伏电池板中加入镉、铅、镍和砷等金属/卤化物可能会引起人们的关注,因为它们可能会对环境造成许多负面影响,尤其是在退役之后。虽然太阳能电池板释放的铅和镉一般较少,但这些释放量可能会增加,造成长期危害。镉和铅如果只是从太阳能电池板中释放出来,就会进入包括土壤和水在内的环境中,对人类健康和生态系统构成重大风险。尤其是镉,会对动物和人类产生深远而持久的负面影响,影响细胞反应、酶的运行和免疫系统的功能。而接触铅则会诱发氧化应激和神经中毒,破坏离子调节途径,损害免疫功能。尽管人们努力减少光伏电池板中有毒金属的释放,但控制其处置和避免环境污染仍是一项挑战。发现光伏电池板制造的替代材料、实施强化的回收程序、进行生物修复以及实施更严格的限制措施,都是减轻环境问题的策略之一。

This study assesses the adoption and operational effectiveness of Environmental Management Systems (EMSs) in Italian wineries, focusing on ISO 14001:2015. It evaluates commitment, planning, communication strategies, emergency preparedness, and employee training practices. Using a comprehensive survey-based methodology, the research elucidates the dynamics of EMS implementation across various scales of winery operations. The research reveals a strong commitment among wineries to environmental objectives such as waste reduction and efficient electricity and water use. However, significant deficiencies were identified in EMS policy implementation, emergency preparedness, and the uptake of ISO 14001:2015 certification, with larger wineries showing more robust engagement in environmental training than smaller ones. The study incorporates five key performance indicators (KPIs) and a predictive model using logistic regression and Random Forest to analyze the likelihood of ISO 14001 certification based on the analyzed variables. The model highlights established processes, environmental policies, and frequent reviews as significant predictors of certification. These findings contribute original value by identifying critical leverage points and barriers affecting EMS effectiveness within the wine sector. The research uncovers nuanced interactions between the scale of operations and management engagement influencing EMSs’ success. It proposes novel, survey-based KPIs essential for assessing EMS performance in wineries, demonstrating their practical utility in pinpointing areas for improvement. The research limitations include potential biases from varying participation rates among surveyed wineries, affecting extrapolation to the broader Italian wine industry.

It evaluates commitment, planning, communication strategies, emergency preparedness, and employee training practices. Using a comprehensive survey-based methodology, the research elucidates the dynamics of EMS implementation across various scales of winery operations. The research reveals a strong commitment among wineries to environmental objectives such as waste reduction and efficient electricity and water use. However, significant deficiencies were identified in EMS policy implementation, emergency preparedness, and the uptake of ISO 14001:2015 certification, with larger wineries showing more robust engagement in environmental training than smaller ones. The study incorporates five key performance indicators (KPIs) and a predictive model using logistic regression and Random Forest to analyze the likelihood of ISO 14001 certification based on the analyzed variables. The model highlights established processes, environmental policies, and frequent reviews as significant predictors of certification. These findings contribute original value by identifying critical leverage points and barriers affecting EMS effectiveness within the wine sector. The research uncovers nuanced interactions between the scale of operations and management engagement influencing EMSs’ success. It proposes novel, survey-based KPIs essential for assessing EMS performance in wineries, demonstrating their practical utility in pinpointing areas for improvement. The research limitations include potential biases from varying participation rates among surveyed wineries, affecting extrapolation to the broader Italian wine industry.

This paper presents the development of a 3D digital model of end-of-service-life buildings to facilitate a step change in preparation of pre-demolition protocols that can eliminate problems of inadequate documentation and extensive time spent in preparing pre-demolition audits. The 3D digital model consists of the following four main components: (i) digitization of paper-based drawings and their conversion to CAD; (ii) automated generation of a 3D digital model from CAD; (iii) corrections to the 3D digital model to account for changes in the lifetime of a building; (iv) a sub-model for performing pre-demolition audit. This paper proposes the innovative approaches of incorporating a minimal amount of human intervention to overcome numerous difficulties in automated drawing analysis, application of augmented reality (AR) in corrections to the 3D digital model, and data compatibility for pre-demolition audit. These processes are demonstrated using one building as case study. Using the digital model, a pre-demolition audit can be prepared in minutes rather than the many days required in current practice without a digital model. The accurate quantification of the quantities and locations of different demolition waste materials and products in buildings to be demolished will enable a systematic and quantitative evaluation of potentials of material and product reuse and eliminate contamination of different demolition waste streams (which may contain hazardous waste), which is the main cause of environmental degradation and downcycling of demolition waste materials.
本文介绍了开发报废建筑三维数字模型的情况,以促进拆除前规程准备工作的逐步改变,从而消除文件记录不足和拆除前审计准备工作耗费大量时间的问题。三维数字模型由以下四个主要部分组成:(i) 将纸质图纸数字化并转换为 CAD;(ii) 根据 CAD 自动生成三维数字模型;(iii) 根据建筑物使用年限的变化对三维数字模型进行修正;(iv) 用于执行拆除前审计的子模型。本文提出了一种创新方法,即采用最少的人工干预来克服自动图纸分析、应用增强现实技术(AR)修正三维数字模型以及拆除前审计数据兼容性方面的诸多困难。我们以一栋建筑为案例对这些过程进行了演示。利用数字模型,拆除前审计工作可在数分钟内完成,而目前在没有数字模型的情况下,需要花费数天时间。准确量化待拆除建筑中不同拆除废料和产品的数量和位置,将有助于对材料和产品的再利用潜力进行系统和定量评估,并消除不同拆除废料流(可能含有危险废物)的污染,这是环境退化和拆除废料循环利用的主要原因。

Pesticides affect biota inside and outside agricultural fields due to their intrinsic mode of action. This study investigated whether pesticide active substances (AS) approved for conventional agriculture in Europe differ in their ecotoxicity from AS approved for organic agriculture. The evaluation was based on official ecotoxicological data for surrogate honeybee, bird, and earthworm species, which also serve as a reference for official environmental risk assessments in the pesticide authorization process. In October 2022, 268 chemical-synthetic AS approved for conventional and 179 nature-based AS approved for organic agriculture were listed in the EU Pesticide Database. Ecotoxicological data were only available for 254 AS approved for use in conventional agriculture and 110 AS approved for use in organic agriculture. The results showed a higher ecotoxicity of conventional AS: 79% (201 AS), 64% (163 AS) and 91% (230 AS) were moderately to acutely toxic to honeybees, birds, and earthworms, respectively, compared to 44% (48 AS), 14% (15 AS) and 36% (39 AS) of AS approved for organic agriculture. We have only considered the potential ecotoxicities of individual substances in this assessment; actual exposure in the field, where multiple AS formulations with other chemicals (including impurities) are applied, will be different. Nevertheless, these results emphasize that an increase in organic agriculture in Europe would reduce the ecotoxicological burden on biodiversity and associated ecosystem services.
农药因其固有的作用模式而影响农田内外的生物群。本研究调查了欧洲批准用于常规农业的农药活性物质(AS)与批准用于有机农业的农药活性物质(AS)在生态毒性方面是否存在差异。评估依据的是蜜蜂、鸟类和蚯蚓等替代物种的官方生态毒理学数据,这些数据也可作为农药授权过程中官方环境风险评估的参考。2022 年 10 月,欧盟农药数据库中列出了 268 种获准用于常规农业的化学合成 AS 和 179 种获准用于有机农业的基于自然的 AS。仅有 254 种获准用于常规农业的 AS 和 110 种获准用于有机农业的 AS 的生态毒理学数据。结果显示,常规 AS 的生态毒性较高:79%(201 种 AS)、64%(163 种 AS)和 91%(230 种 AS)的 AS 对蜜蜂、鸟类和蚯蚓有中度至急性毒性,而获准用于有机农业的 AS 的生态毒性分别为 44%(48 种 AS)、14%(15 种 AS)和 36%(39 种 AS)。在本次评估中,我们只考虑了单个物质的潜在生态毒性;在田间应用含有其他化学品(包括杂质)的多种 AS 配方时,实际接触情况会有所不同。尽管如此,这些结果强调,欧洲有机农业的增加将减少对生物多样性和相关生态系统服务的生态毒理学负担。

Fe/Mn (hydr)oxides are metallic compounds that exhibit significant redox activity in environmental media and play a pivotal role in geochemical processes, thereby influencing the fate of metals in porous media. The morphology of Fe/Mn (hydr)oxides in natural environments and their interactions with trace metals are significantly influenced by the presence of natural organic matter (NOM). However, there is limited understanding regarding the formation, transport, and stability of Fe/Mn (hydr)oxides in the environment. The present study employed humic acid (HA) as a representative NOM material to investigate the positive influence of HA on the formation of Fe/Mn colloids. However, there remains limited comprehension regarding the formation, transport, and stability of Fe/Mn (hydr)oxides in the natural environment. In this study, we investigated the positive effect of natural organic matter (NOM) on the formation of Fe/Mn colloids using humic acid (HA) as a representative NOM material. We comprehensively characterized the chemical and physical properties of HA–Fe/Mn colloids formed under various environmentally relevant conditions and quantitatively analyzed their subsequent aggregation and stability behaviors. The findings suggest that the molar ratios of C to Fe/Mn (hydr)oxide play a pivotal role in influencing the properties of HA–Fe/Mn colloids. The formation and stability of HA–Fe/Mn colloids exhibit an upward trend with increasing initial molar ratios of C to Fe/Mn. Redox and metal–carboxylic acid complexation reactions between HA and hydrated iron/manganese oxides play a pivotal role in forming colloidal HA–Fe/Mn complexes. Subsequent investigations simulating porous media environments have demonstrated that the colloidal structure resulting from the interaction between HA and Fe/Mn facilitates their migration within surrounding porous media while also enhancing their retention in the surface layers of these media. This study offers novel insights into the formation and stabilization mechanisms of HA–Fe/Mn colloids, which are pivotal for comprehending the behavior of Fe/Mn colloids and the involvement of Fe/Mn (hydr)oxides in geochemical cycling processes within porous media.

Increased daily exposure to fine particulate matter air pollution (PM2.5) is associated with increased morbidity, yet high exposures over shorter timeframes (e.g., hourly) may also play a role. Transportation is a milieu for increased transient pollution exposures. Both the road traveled and nearby roadways (i.e., surrounding road density) may play a role in increased PM2.5 exposure during commutes. For 2311 min of commutes, corresponding to 25 participants, we obtained in-vehicle PM2.5 exposures using personal monitors and, through GPS data, road features, including road density and road type (e.g., highway vs. local roads). We considered the density of both the surrounding highways and the local roads at 500 m and 1000 m resolutions. We estimated associations of road features with minute-averaged in-vehicle PM2.5 by applying linear mixed-effects models with random intercepts and autoregressive errors. The difference in log PM2.5, comparing the highest vs. lowest quartile of highway road density at 1 km resolution, was 0.09 log μg/m3 (95% confidence interval: 0, 0.19), which was similar to the difference between driving on highways vs. local roads (0.07 log μg/m3 (95% confidence interval: 0.00, 0.14)). Estimated differences were attenuated for local road density and 500 m resolution. The results were robust to adjustment for meteorology and ambient PM2.5. Unlike road features such as speed and road type, the surrounding road density is less modifiable during transportation. Therefore, road choice may not have a large impact on personal PM2.5 exposures.
每天接触更多的细颗粒物空气污染(PM2.5)与发病率的增加有关,但在较短时间内(如每小时)接触更多的细颗粒物空气污染可能也是一个原因。交通是增加瞬时污染暴露的环境。在通勤过程中,行驶的道路和附近的道路(即周围的道路密度)都可能对 PM2.5 暴露的增加起作用。我们使用个人监测仪获得了 25 名参与者 2311 分钟通勤时间内的车内 PM2.5 暴露情况,并通过 GPS 数据获得了道路特征,包括道路密度和道路类型(如高速公路与地方道路)。我们以 500 米和 1000 米的分辨率考虑了周围高速公路和地方道路的密度。我们采用具有随机截距和自回归误差的线性混合效应模型来估计道路特征与车内 PM2.5 分钟均值之间的关系。在 1 公里分辨率下,比较公路道路密度的最高四分位数与最低四分位数,PM2.5 的对数差异为 0.09 log μg/m3(95% 置信区间:0,0.19),这与在公路上行驶与在地方道路上行驶的差异(0.07 log μg/m3(95% 置信区间:0.00,0.14))相似。当地道路密度和 500 米分辨率削弱了估计差异。结果对气象和环境 PM2.5 的调整是稳健的。与车速和道路类型等道路特征不同,周围道路密度在运输过程中较难改变。因此,道路选择可能不会对个人 PM2.5 暴露产生很大影响。
