Long-term exposure to pollution can lead an increase in the rate of decline lung function, especially older individuals and those with chronic obstructive pulmonary disease (COPD), whereas shorter-term at higher levels has been implicated causing excess deaths from ischaemic heart exacerbations COPD. We aimed assess effects on respiratory cardiovascular responses walking down a busy street high compared traffic-free area lower adults.In this randomised, crossover study, we recruited men...
Air pollution is a worldwide environmental health issue. Increasingly, reports suggest that poor air quality may be associated with mental problems, but these studies often use global measures and rarely focus on early development when psychopathology commonly emerges. To address this, we combined high-resolution exposure estimates prospectively-collected phenotypic data to explore concurrent longitudinal associations between pollutants of major concern in urban areas problems childhood...
Citizen sensing, or the use of low-cost and accessible digital technologies to monitor environments, has contributed new types environmental data practices. Through a discussion participatory research into air pollution sensing with residents northeastern Pennsylvania concerned about effects hydraulic fracturing, we examine how for generating also give rise problems analysing making sense citizen-gathered data. After first outlining citizen practices collaboratively developed monitoring...
BackgroundAir pollution in Beijing has been improving through implementation of the Air Pollution Prevention and Control Action Plan (2013–17), but its implications for respiratory morbidity have not directly investigated. We aimed to assess potential effects air-quality improvements on health by investigating number cases acute exacerbations chronic obstructive pulmonary disease (COPD) advanced air each year.MethodsDaily city-wide concentrations PM10, PM2·5, PMcoarse (particulate matter...
Abstract. The Atmospheric Pollution and Human Health in a Chinese Megacity (APHH-Beijing) programme is an international collaborative project focusing on understanding the sources, processes health effects of air pollution Beijing megacity. APHH-Beijing brings together leading China UK research groups, state-of-the-art infrastructure quality models to work four themes: (1) sources emissions pollutants; (2) atmospheric affecting urban pollution; (3) exposure impacts; (4) interventions...
Low emission zones (LEZ) are an increasingly common, but unevaluated, intervention aimed at improving urban air quality and public health. We investigated the impact of London's LEZ on children's respiratory health.We did a sequential annual cross-sectional study 2164 children aged 8-9 years attending primary schools between 2009-10 2013-14 in central London, UK, following introduction February, 2008. examined association modelled pollutant exposures nitrogen oxides (including dioxide [NO2])...
Abstract. The inaccurate quantification of personal exposure to air pollution introduces error and bias in health estimations, severely limiting causal inference epidemiological research worldwide. Rapid advancements affordable, miniaturised sensor technologies offer the potential address this limitation by capturing high variability during daily life large-scale studies with unprecedented spatial temporal resolution. However, concerns remain regarding suitability novel sensing for...
Estimating air pollution exposure has long been a challenge for environmental health researchers. Technological advances and novel machine learning methods have allowed us to increase the geographic range accuracy of models, making them valuable tool in conducting studies identifying hotspots pollution. Here, we created prediction model daily PM2.5 levels Greater London area from 1st January 2005 31st December 2013 using an ensemble approach incorporating satellite aerosol optical depth...
Despite the London Underground (LU) handling on average 2.8 million passenger journeys per day, characteristics and potential health effects of elevated concentrations metal-rich PM2.5 found in this subway system are not well understood. Spatial monitoring campaigns were carried out to characterise health-relevant chemical physical properties across LU network, including diurnal day-to-day variability spatial distribution (above ground, depth below ground line). Population-weighted station...
Background Acute associations between mortality and ozone are largely accepted, though recent evidence is less conclusive. Evidence on ozone–heat interaction sparse. We assess effects of ozone, heat, their interaction, in Britain. Methods summer were estimated using data from 15 conurbations England Wales (May–September, 1993–2003). 2-day means daily maximum 8-h entered into case series analyses, controlling for particulate matter with aerodynamic diameter <10 μm, natural cubic splines...
Here we describe the development of London Hybrid Exposure Model (LHEM), which calculates exposure Greater population to outdoor air pollution sources, in-buildings, in-vehicles, and outdoors, using survey data when where people spend their time. For comparison estimate misclassification compared Londoners LHEM with at residential address, a commonly used metric in epidemiological research. In 2011, mean annual sources was estimated be 37% lower for PM2.5 63% NO2 than address. These...
Background:Investigators have examined whether heat mortality risk is increased in neighborhoods subject to the urban island (UHI) effect but not identified degrees of difference susceptibility and cold between cool hot areas, which we call acclimatization UHI.Objectives:We developed methods examine quantify degree heat- cold-related relation UHI anomalies applied these London, UK.Methods:Case–crossover analyses were undertaken on 1993–2006 data from London decile groups defined by average...
Severe episodic air pollution blankets entire cities and regions have a profound impact on humans their activities. We compiled daily fine particle (PM2.5) data from 100 in five continents, investigated the trends of number, frequency, duration episodes, compared these with baseline trend pollution. showed that factors contributing to events are complex; however, long-term measures abate emissions all anthropogenic sources at times is also most efficient way reduce occurrence severe events....
Prenatal exposure to air pollution is associated with adverse neurologic consequences in childhood. However, the relationship between utero and neonatal brain development unclear. We modelled maternal nitrogen dioxide (NO2) particulate matter (PM2.5 PM10) at postcode level date of conception birth studied effect prenatal on morphology 469 (207 male) healthy neonates, gestational age ≥36 weeks. Infants underwent MR neuroimaging 3 Tesla 41.29 (36.71–45.14) weeks post-menstrual (PMA) as part...
Environmental temperature is negatively associated with blood pressure (BP), and hypertension may exacerbate this association. The aim of study to investigate whether hypertensive individuals are more susceptible acute BP increases following decrease than non-hypertensive individuals. panel consisted 126 125 (n = 251) elderly participants who completed 940 clinical visits during the winter 2016 summer 2017 in Beijing, China.
