1. Understanding Heat Exposure Risks and Adaptation Behaviors Among Elderly Asian Communities in New York City.
1. 纽约市亚裔老年社区的热暴露风险与适应行为研究PMID:日期:2025-09-25Extreme heat exposure is a leading cause of climate-related illness and death in cities, with low-income older adults being particularly vulnerable. While outdoor air temperature is a key determinant of individual heat exposure, there is limited understanding of how personal attributes, the built environment, and adaptive behaviors influence personal heat exposure among low-income elderly individuals. From August to September 2023, we recruited 45 older Asian adults living in New York City to examine the impact of heat risk perception, climate change knowledge, home adaptation behaviors, and demographic and socioeconomic factors on individual heat exposure. Participants had an average age of 74.8 years (range: 63-89) and faced economic challenges, with 64% reporting an annual household income below USD 40,000. Limited financial resources, including low annual incomes and fixed retirement incomes, may contribute to the low use of air conditioning for cooling at home. The results also showed that personal heat exposure exceeded ambient heat exposure, particularly during nighttime. Age and outdoor air temperature were significant factors that increased personal heat exposure, while strong adaptive behaviors helped mitigate exposure. This pilot study underscores the need for targeted strategies to reduce personal heat exposure and vulnerability among this population. Efforts should focus on increasing access to affordable cooling options, expanding energy assistance programs, and promoting adaptive behaviors through community outreach and education.

2. Assessing Community Vulnerability to Extreme Events in the Presence of Contaminated Sites and Waste Management Facilities: An Indicator Approach.
2. 在存在污染场地和废物管理设施的情况下评估社区对极端事件的脆弱性:一种指标方法PMID:日期:2024-01Communities across the world are facing extreme events, such as excessive heat, droughts, floods, and wildfires. In the presence of contaminated sites and waste management facilities, communities must consider the impacts of potential releases from these sites due to such events. Impacts of extreme events on sites and consequently on surrounding, often disadvantaged communities result from complex interactions between natural, physical, and social factors. A conceptual framework was developed to identify and provide a shared understanding of key vulnerabilities and pathways that transcend disciplines. A transparent and replicable method was developed to create mappable indicators that represent contaminated sites, waste facilities, contaminant transport via air and water, and population sensitivities. This method can be applied as a screening step to assist states and local communities in prioritizing targeted strategies and resources and determining where in-depth assessments are needed. These indicators can facilitate communication with a broad audience more easily than complex modeling approaches or aggregated indices. Case study results demonstrate the importance of considering indicators in conjunction with each other. The indicator method was developed together with U.S.-based partners, but can be adapted for other countries seeking to understand the potential impacts of extreme events on contaminated sites and communities.

3. Nighttime light perspective in urban resilience assessment and spatiotemporal impact of COVID-19 from January to June 2022 in mainland China.
3. 夜间灯光视角下的城市韧性评估与2022年1月至6月中国大陆COVID-19的时空影响PMID:日期:2023-06-21The outbreak of the coronavirus disease 2019 (COVID-19) epidemic has resulted in large threats and damage to society and the economy. In this study, we evaluate and verify the comprehensive resilience and spatiotemporal impact of the COVID-19 epidemic from January to June 2022 in mainland China based on multisource data. First, we adopt a combination of the mandatory determination method and the coefficient of variation method to determine the weight of the urban resilience assessment index. Furthermore, Beijing, Shanghai, and Tianjin were selected to verify the feasibility and accuracy of the resilience assessment results based on the nighttime light data. Finally, the epidemic situation was dynamically monitored and verified with population migration data. The results show that urban comprehensive resilience of mainland China is shown in the distribution pattern of higher resilience in the middle east and south and lower resilience in the northwest and northeast. Moreover, the average light intensity index is inversely proportional to the number of newly confirmed and treated cases of COVID-19 in the local area. This study provides a scientific reference to improve the comprehensive resilience of cities to achieve the goals of sustainable development (SDGs 11): make cities and human settlements resilient and sustainable.

4. The effects of city morphology on airborne transmission of COVID-19. Case study: Port Said City, Egypt.
PMID:日期:2023-06-12Looking beyond COVID-19 outbreak, Scholars continue to develop innovative approaches to bring the city on to health and safety. Recent studies have indicated that urban spaces could produce or propagate pathogens, which is an urgent topic at the city level. However, there is a dearth of studies investigating the interrelationship between urban morphology and pandemics outbreak at the neighborhood level. Accordingly, this research will trace the effect of cities morphologies on the rate of spread of COVID-19 through a simulation study held on five areas that form the urban morphology of Port Said City, using Envi-met software. Results are explored based on the degree of concentration and rate of diffusion of coronavirus particles. It was observed on a regular basis that wind speed has a directly proportional relationship with the diffusion of the particles and an inversely proportional relationship with the concentration of the particles. However, certain urban characteristics led to inconsistent and opposing results like wind tunnels, shaded arcades, height variance, and spacious in-between spaces. Moreover, it is obvious that the city morphology is being transformed over time toward safer conditions; urban areas constructed recently have low vulnerability to respiratory pandemics outbreak compared to older areas.

5. How does COVID-19 lockdown affect air quality: Evidence from Lanzhou, a large city in Northwest China.
5. COVID-19封锁如何影响空气质量:来自中国西北大城市兰州的证据PMID:日期:2023-04-21Coronavirus disease (COVID-19) has disrupted health, economy, and society globally. Thus, many countries, including China, have adopted lockdowns to prevent the epidemic, which has limited human activities while affecting air quality. These affects have received attention from academics, but very few studies have focused on western China, with a lack of comparative studies across lockdown periods. Accordingly, this study examines the effects of lockdowns on air quality and pollution, using the hourly and daily air monitoring data collected from Lanzhou, a large city in Northwest China. The results indicate an overall improvement in air quality during the three lockdowns compared to the average air quality in the recent years, as well as reduced PM, PM, SO, NO, and CO concentrations with different rates and increased O concentration. During lockdowns, Lanzhou's "morning peak" of air pollution was alleviated, while the spatial characteristics remained unchanged. Further, ordered multi-classification logistic regression models to explore the mechanisms by which socioeconomic backgrounds and epidemic circumstances influence air quality revealed that the increment in population density significantly aggravated air pollution, while the presence of new cases in Lanzhou, and medium- and high-risk areas in the given district or county both increase the likelihood of air quality improvement in different degrees. These findings contribute to the understanding of the impact of lockdown on air quality, and propose policy suggestions to control air pollution and achieve green development in the post-epidemic era.

6. {"_":"Source apportionment of PM before and after COVID-19 lockdown in an urban-industrial area of the Lisbon metropolitan area, Portugal.","sub":["2.5"]}
6. {"_":"葡萄牙里斯本大都市区某城市工业区COVID-19封锁前后PM的来源解析。","sub":["PMID:日期:2023-02-16The lockdowns held due to the COVID-19 pandemic conducted to changes in air quality. This study aimed to understand the variability of PM levels and composition in an urban-industrial area of the Lisbon Metropolitan Area and to identify the contribution of the different sources. The composition of PM was assessed for 24 elements (by PIXE), secondary inorganic ions and black carbon. The PM mean concentration for the period (December 2019 to November 2020) was 13 ± 11 μg.m. The most abundant species in PM were BC (19.9%), SO (15.4%), NO (11.6%) and NH (5.3%). The impact of the restrictions imposed by the COVID-19 pandemic on the PM levels was found by comparison with the previous six years. The concentrations of all the PM components, except Al, Ba, Ca, Si and SO , were significantly higher in the winter/pre-confinement than in post-confinement period. A total of seven sources were identified by Positive Matrix Factorisation (PMF): soil, secondary sulphate, fuel-oil combustion, sea, vehicle non-exhaust, vehicle exhaust, and industry. Sources were greatly influenced by the restrictions imposed by the COVID-19 pandemic, with vehicle exhaust showing the sharpest decrease. Secondary sulphate predominated in summer/post-confinement. PM levels and composition also varied with the types of air mass trajectories.

7. {"_":"Impact of mobility restrictions on NO concentrations in key Latin American cities during the first wave of the COVID-19 pandemic.","sub":["2"]}
PMID:日期:2023-01-06Between March and June 2020, activity in the major cities of Latin America declined due to containment efforts implemented by local governments to avoid the rapid spread of COVID-19. Our study compared 2020 with the previous year and demonstrated a considerable drop in tropospheric NO levels obtained by the SENTINEL 5P satellite in major Latin American cities. Lima (47.5%), Santiago (36.1%), São Paulo (27%), Rio de Janeiro (23%), Quito (18.6%), Bogota (17.5%), Buenos Aires (16.6%), Guayaquil (15.3%), Medellin (14.2%), La Paz (9.5%), Belo Horizonte (7.8%), Mexico (7.6%) and Brasilia (5.9%) registered statistically significant decreases in NO concentrations during the study period. In addition, we analyzed mobility data from Google and Apple reports as well as meteorological information from atmospheric reanalysis data along with satellite fields between 2011 and 2020, and performed a refined multivariate analysis (non-negative matrix approximation) to show that this decrease was associated with a reduction in population mobility rather than meteorological factors. Our findings corroborate the argument that confinement scenarios may indicate how air pollutant concentrations can be effectively reduced and managed.

8. Urban heat in Johannesburg and Ekurhuleni, South Africa: A meter-scale assessment and vulnerability analysis.
PMID:日期:2022-12Heat stress is an important threat for human health and urban areas are affected at higher rates compared to rural environments. Additionally, climate change will increase the vulnerability towards urban heat stress in the future. Current high-resolution urban heat stress assessments are limited in time and space due to the high computational costs. In this paper, the UrbClim numerical model is used to simulate urban heat accurately at a fast rate and high spatial resolution for the cities of Johannesburg and Ekurhuleni, South Africa. Using detailed terrain information, (future) urban heat stress assessments are provided at 30 m resolution for both city agglomerations, while meter-scale simulations are executed for a selection of neighborhoods. These model simulations are evaluated using an extensive monitoring campaign in which the local community was heavily engaged. Distinct spatial differences in the urban heat island effect are observed, with greatest heat stress in areas with high building densities and low vegetation numbers. These areas are often characterized by lower socio-economic living conditions. The meter-scale analysis further shows the importance of shade provided by vegetation to lower heat stress in both present and future climate. These assessments offer assistance in the design of climate-resilient urban planning strategies.

9. The concentration of BTEX in selected urban areas of Malaysia during the COVID-19 pandemic lockdown.
PMID:日期:2022-07-13Volatile organic compounds (VOCs) such as benzene, toluene, ethylbenzene and xylene (BTEX) are air pollutants that harm human health. This study aims to identify BTEX concentrations before the lockdown known as the Movement Control Order was imposed (BMCO), during the implementation of the Movement Control Order (MCO), and then during the Conditional Movement Control Order (CMCO). These orders were introduced during the COVID-19 pandemic in Malaysia. The study utilised data measured by the continuous monitoring of BTEX using online gas chromatography instruments located at three urban area stations. The results showed that the BTEX concentrations reduced by between -38% and -46% during the MCO compared to the BMCO period. The reduction of human mobility during the MCO and CMCO influenced the lower BTEX concentrations recorded at a station within the Kuala Lumpur area. The results of the BTEX diagnostic ratios and principal component analysis showed that the major source of BTEX, especially during the BMCO and CMCO periods, was motor vehicle emissions. Further investigation, using correlation analysis and polar plots, showed that the BTEX concentrations were also influenced by meteorological variables such as wind speed, air temperature and relative humidity.

10. Revisiting air quality during lockdown persuaded by second surge of COVID-19 of megacity Delhi, India.
10. 重新审视印度德里 megacity 在 COVID-19 第二波疫情推动的封锁期间的空气质量PMID:日期:2022-01-06Is the impact of city-scale lockdown in response to 2nd surge of COVID-19, behavioural changes in people owing to yearlong cohabitation with COVID-19, and partial vaccination on air quality different from the impact of nationwide lockdown during COVID-19's 1st surge in March 2020? Targeting this objective, the present work has selected four phases pre-lockdown and lockdown of 1st and 2nd cycles of lockdown taking average air quality index (NAQI) from Central Pollution Control Board (CPCB). The results clearly show that both the nationwide lockdown and the city-scale restriction are responsible for improving air quality in India's megacity Delhi, but the rate of improvement was higher (39%) during the first cycle of lockdown (nationwide) than during the second cycle of lockdown (city-scale). During city-scale lockdown, the disparity in NAQI between the core and the periphery is obvious. Due to the effect of economic activities surrounding Delhi, around 10 km of the city's interior has experienced high NAQI. The reason for the lower NAQI improvement during the second lockdown cycle is likely due to relief from initial fear following a year of cohabitation with COVID-19, partial vaccination, and partial relaxation in industrial sectors to avoid the economic hardships experienced during the first lockdown cycle.
