Air pollutants such as NO2 and PM2.5 have consistently been linked to mortality, but only few previous studies addressed associations with long-term exposure black carbon (BC) ozone (O3). We investigated the association between PM2.5, PM10, BC, NO2, O3 mortality in a Danish cohort of 49,564 individuals who were followed up from enrollment 1993–1997 through 2015. Residential address history 1979 onwards was combined air pollution obtained by state-of-the-art, validated, THOR/AirGIS modelling...
Studies on health effects of long-term exposure to specific PM2.5 constituents are few. Previous studies have reported an association between black carbon (BC) and cardiovascular diseases (CVD) a few found sulfate mortality. These studies, however, relied mainly data from centrally located air-monitoring stations, which is crude approximation personal exposure. We focused chemical PM2.5, i.e. elemental primary organic carbonaceous particles (BC/OC), sea salt, secondary inorganic aerosols...
Abstract Objective To investigate the association between long term residential exposure to road traffic and railway noise risk of incident dementia. Design Nationwide prospective register based cohort study. Setting Denmark. Participants 1 938 994 adults aged ≥60 years living in Denmark January 2004 31 December 2017. Main outcome measures Incident cases all cause dementia subtypes (Alzheimer’s disease, vascular dementia, Parkinson’s disease related dementia), identified from national...
Air pollution, road traffic noise and lack of greenness coexist in urban environments have all been associated with type 2 diabetes. We aimed to investigate how these co-exposures were diabetes a multi-exposure perspective.We estimated 5-year residential mean exposure fine particles (PM2.5), ultrafine (UFP), elemental carbon (EC), nitrogen dioxide (NO2) at the most (LdenMax) least (LdenMin) exposed facade for persons aged > 50 years living Denmark 2005 2017. For each air pollutant, we total...
ABSTRACT Background Epidemiologic studies have demonstrated that ambient concentrations of particulate matter < 2.5 μm (PM ) are associated with reduced fecundability, the per cycle probability conception. The specific constituents driving this association unknown. Objectives We examined between PM and fecundability in a Danish preconception cohort study. Methods During 2007–2018, we enrolled female pregnancy planners an Internet‐based included 5905 participants who had been trying to...
Background: Adverse health effects of air pollution have been reported in previous studies with varying methodological approaches to the exposure assessment. Measuring individual for large-scale epidemiological is infeasible, calling refined modeling tools. We evaluated performance Geographical Information System–based and human system (AirGIS). Methods: Modeled concentrations were against measured particulate matter (PM) less than 10 2.5 μm aerodynamic diameter (PM /PM ) from two fixed-site...
Exposure to ambient air pollution has been linked asthma, allergic rhinitis, and other inflammatory disorders, but little is known about the underlying mechanisms.We studied potential mechanisms leading from prenatal exposure asthma allergy in childhood.Long-term nitrogen dioxide (NO2) as well particulate matter with a diameter of ≤2.5 ≤10 μm (PM2.5 PM10) were modeled at residence level conception 6 years age 700 Danish children followed clinically for development allergy. Nasal mucosal...
Background: Ambient air pollution exposure has been associated with childhood asthma, but previous studies have primarily focused on prevalence of asthma and asthma-related outcomes urban traffic-related exposures. Objective: We examined nationwide associations between pre- postnatal to ambient components incidence in children age 0–19 y. Methods: Asthma was identified from hospital admission, emergency room, outpatient contacts among all live-born singletons born Denmark 1998 2016. linked...
Abstract Aims The three correlated environmental exposures (air pollution, road traffic noise, and green space) have all been associated with the risk of myocardial infarction (MI). present study aimed to analyse their independent cumulative association MI. Methods results In a cohort Danes aged 50 or older in period 2005–17, 5-year time-weighted average exposure fine particles (PM2.5), ultrafine particles, elemental carbon, nitrogen dioxide (NO2), noise at most least exposed façades...
Telomere length (TL) is a biomarker of biological aging that may be affected by prenatal exposure to air pollution. The aim this study was assess the association between pollution and TL in maternal blood cells (leukocytes), placenta umbilical cord cells, sampled immediately after birth 296 Danish mother-child pairs from cohort. Exposure data obtained using high-resolution spatial–temporal modeling system DEHM-UBM-AirGIS for PM2.5, PM10, SO2, NH4+, black carbon (BC), organic (OC), CO, O3,...
Modelling of ambient particle number concentrations (PNC) has been implemented in the Danish air quality modelling system DEHM/UBM/AirGIS and evaluated with long-term measurements. We dynamical processes regional scale model DEHM using M7 aerosol dynamics module (presented accompanying article by Frohn et al., 2021), we developed models for PNC at local (UBM) street (OSPM), a first approximation without including as presented this article. Outdoor concentration estimates are provided front...
High-resolution air quality (AQ) maps based on street-by-street measurements have become possible through large-scale mobile measurement campaigns. Such campaigns produced data-only and been used to produce empirical models [i.e., land use regression (LUR) models]. Assuming that all road segments are measured, we developed a mixed model framework predicts concentrations by an LUR model, while allowing deviate from the prediction between-segment variation as random effect. We Google Street...
Hyperlocal air quality maps are becoming increasingly common, as they provide useful insights into the spatial variation and sources of pollutants. In this study, we produced several high-resolution concentration to assess differences three traffic-related pollutants, Nitrogen dioxide (NO2), Black Carbon (BC) Ultrafine Particles (UFP), in Amsterdam, Netherlands, Copenhagen, Denmark. All were based on a mixed-effect model approach by using state-of-the-art mobile measurements conducted Google...
Air pollution levels can vary significantly over short distances, particularly in urban areas and near emission sources. This study examined the performance of low-cost sensor devices for monitoring NO2, O3, PM2.5 along two closely spaced (average 8 m) routes Copenhagen, Denmark. One route was located a lake (Route 1) other busy road 2). The were walked tandem 84 h. mode deployment determined using an accelerometer, gyroscope, light sensor, achieving 97.4 % accuracy rate. Field calibration...
To assess the role of occupational noise exposure on pregnancy complications in urban Nordic populations. A study population covering five metropolitan areas Denmark, Finland, Norway and Sweden was generated using national birth registries linked with residential environmental exposures sociodemographic variables. The data covered all pregnancies during 5-11 year periods 2004‒2016, resulting 373 184 pregnancies. Occupational based a Swedish-developed job-exposure-matrix, containing measured...
Air pollution has become one of the most critical global challenges, exacerbated by climate change and growing human population. It poses a significant threat to public health, particularly in urban areas where high population density increased vehicle numbers contribute poor air quality. The primary motivation this study is estimate street-scale Be&#351;ikta&#351;, &#304;stanbul, T&#252;rkiye, with Operational Street Pollution Model (OSPM&#174;)....
