Objective To investigate whether the incidence of dementia is related to residential levels air and noise pollution in London. Design Retrospective cohort study using primary care data. Setting 75 Greater London practices. Participants 130 978 adults aged 50–79 years registered with their general practices on 1 January 2005, no recorded history or home residence. Primary secondary outcome measures A first diagnosis and, where specified, subgroups Alzheimer’s disease vascular during...
<h3>Abstract</h3> <h3>Objective</h3> To investigate the relation between exposure to both air and noise pollution from road traffic birth weight outcomes. <h3>Design</h3> Retrospective population based cohort study. <h3>Setting</h3> Greater London surrounding counties up M25 motorway (2317 km<sup>2</sup>), UK, 2006 2010. <h3>Participants</h3> 540 365 singleton term live births. <h3>Main outcome measures</h3> Term low (LBW), small for gestational age (SGA) at term, weight. <h3>Results</h3>...
This paper describes the development of a model for assessing TRAffic Noise EXposure (TRANEX) in an open-source geographic information system. Instead using proprietary software we developed our own two main reasons: 1) so that treatment source geometry, traffic (flows/speeds/spatially varying diurnal profiles) and receptors matched as closely possible to air pollution modelling being undertaken TRAFFIC project, 2) optimize performance practical reasons needing implement noise with detailed...
Road traffic gives rise to noise and air pollution exposures, both of which are associated with adverse health effects especially for cardiovascular disease, but mechanisms may differ. Understanding the variability in correlations between these pollutants is essential understand better their separate joint on human health. We explored associations modelled using different spatial units area characteristics London 2003-2010. annual average exposures road (LAeq,24h, Lden, LAeq,16h, Lnight)...
Abstract Purpose The World Health Organisation (WHO) recently ranked air pollution as the major environmental cause of premature death. However, significant potential health and societal costs poor mental in relation to quality are not represented WHO report due limited evidence. We aimed test hypothesis that long-term exposure is associated with health. Methods A prospective longitudinal population-based survey was conducted 1698 adults living 1075 households South East London, from 2008...
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])...
There is relatively little evidence of health effects long-term exposure to traffic-related pollution in susceptible populations. We investigated whether traffic air and noise was associated with all-cause mortality or hospital readmission for myocardial infarction (MI) among survivors admission MI. Patients from the Myocardial Ischaemia National Audit Project database resident Greater London (n = 18,138) were followed death High spatially-resolved annual average (11 metrics primary traffic,...
Evidence for associations between ambient air pollution and preterm birth stillbirth is inconsistent. Road traffic produces both pollutants noise, but few studies have examined these co-exposures together none to date with all-cause or cause-specific stillbirths. To analyse the relationship long-term exposure noise at address level during pregnancy risk of stillbirth. The study population comprised 581,774 live still births in Greater London area, 2006-2010. Outcomes were (<37 completed...
Background Growing evidence suggests that air pollution exposure may adversely affect the brain and increase risk for psychiatric disorders such as schizophrenia depression. However, little is known about potential role of in severity relapse following illness onset. Aims To examine longitudinal association between residential mental health service use (an indicator relapse) among individuals with first presentations psychotic mood disorders. Method We identified aged ≥15 years who had...
This study explores the cobenefits of reduced nitrogen dioxide (NO2), ozone (O3), and particulate matter (PM), through net zero (NZ) climate policy in UK. Two alternative NZ scenarios, balanced (BNZP) widespread innovation (WI) pathways, from UK Climate Change Committee's Sixth Carbon Budget, were examined using a chemical transport model (CTM). Under existing policy, Business as Usual (BAU), reductions NO2 PM predicted by 2030 due to new vehicle technologies but plateau 2040. The BNZP WI...
<h3>Objectives</h3> The epidemiological evidence for adverse health effects of long-term exposure to air and noise pollution from traffic is not coherent. Further, the relative roles background versus near concentrations in this process are unclear. We investigated relationships between modelled incident cardiorespiratory disease London. <h3>Methods</h3> Among 211 016 adults aged 40–79 years registered 75 Greater London practices 2005 2011, first diagnosis a range cardiovascular respiratory...
Climate change poses a dangerous and immediate threat to the health of populations in UK worldwide. We aimed model different scenarios assess co-benefits that result from mitigation actions.In this modelling study, we combined detailed techno-economic energy systems (UK TIMES), air pollutant emission inventories, sophisticated pollution (Community Multi-scale Air Quality), previously published associations between concentrations outcomes. used four focused on implications fine particulate...
Abstract. During March–June 2017 emissions of nitrogen oxides were measured via eddy covariance at the British Telecom Tower in central London, UK. Through use a footprint model expected simulated from spatially resolved National Atmospheric Emissions Inventory for and compared with emissions. These shown to underestimate during daytime by factor 1.48, but they agreed well overnight. Furthermore, underestimations mapped, areas around measurement site responsible differences inferred. It was...
Longitudinal evidence on the association between air pollution and blood pressure (BP) in adolescence is scarce. We explored this an ethnically diverse cohort of schoolchildren. Sex-stratified, linear random-effects modelling was used to examine how modelled residential exposure annual average nitrogen dioxide (NO 2 ), particulate matter (PM 2.5, PM 10 ) ozone (O 3 measures μg/m , associated with pressure. Estimates were based 3,284 adolescents; 80% from ethnic minority groups, recruited 51...
Evidence on the effects of long-term exposure to traffic pollution health is inconsistent. In Greater London we examined associations between and emergency hospital admissions for cardio-respiratory diseases by applying linear piecewise Poisson regression models in a small-area analysis. For both results children adults were close unity. elderly, found negative whereas non-linear characterized positive risks lowest highest category. An increased risk was observed among those living areas...
The burden of diseases attributable to air pollution is comparable those global health risks such as unhealthy diets and tobacco smoking, with many sources also emitting climate heating gases. In this UK study we estimated the co-benefits Net Zero (NZ) policy on benefits reduction, increased active travel, outdoor exposure inequalities indoor changes. focused two largest sources, road transport building heating, comparisons made between NZ existing policy, referred Business Usual (BAU)....
Long-term exposure to primary traffic pollutants may be harmful for health but few studies have investigated effects on mortality. We examined associations six with all-cause and cause-specific mortality in 2003-2010 at small-area level using linear piecewise Poisson regression models. In models most showed negative or null association all-cause, cardiovascular respiratory the we observed positive lowest range (e.g. relative risk (RR) 1.07 (95% credible interval (CI) = 1.00-1.15) per 0.15...
Abstract: Air pollution strategies in London over the last 12 years have centered upon congestion charging scheme, and at same time, fitting of particle traps to buses, low emissions zone (LEZ), Mayor's Quality Strategy (MAQS). The 2003 scheme achieved much scheme's aims, but demand travel need for road space eroded initial benefits. While on buses was predicted reduce particulate matter (PM) exhaust emissions, introduction phases 1 2 LEZ MAQS were both modest emission impacts. Reliance new...
