Building ventilation systems must get much better
Pregnancy, infancy, and childhood are sensitive windows for environmental exposures. Yet the health effects of exposure to nano- microplastics (NMPs) remain largely uninvestigated or unknown. Although plastic chemicals a well-established research topic, impacts particles unexplored, especially with regard early life exposures.This commentary aims summarize knowns unknowns around child- pregnancy-relevant exposures NMPs via inhalation, placental transfer, ingestion breastmilk, dermal...
If some countries lead by example, standards may increasingly become normalized.
In urban environments, airborne particles are continuously emitted, followed by atmospheric aging. Also, emitted elsewhere, transported winds, contribute to the aerosol. We studied effective density (mass-mobility relationship) and mixing state with respect of in central Copenhagen, wintertime. The results related particle origin, morphology, Using a differential mobility analyzer-aerosol mass analyzer (DMA-APM), we determined that diameter range 50–400 nm were two groups: porous soot...
The majority of airborne particles in residences, when expressed as number concentrations, are generated by the residents themselves, through combustion/thermal related activities. These have a considerably smaller diameter than 2.5 μm and, due to combination their small size, chemical composition (e.g. soot) and intermittently very high should be regarded having potential cause adverse health effects. In this study, time resolved particle measurements were conducted for seven consecutive...
Abstract This is an account that should be heard of important struggle: the struggle a large group experts who came together at beginning COVID-19 pandemic to warn world about risk airborne transmission and consequences ignoring it. We alerted World Health Organization potential significance SARS-CoV-2 urgent need control it, but our concerns were dismissed. Here we describe how this happened consequences. hope by reporting story can raise awareness importance interdisciplinary collaboration...
Exposure to diesel exhaust causes inflammatory responses. Previous controlled exposure studies at a concentration of 300 μg/m3 particles mainly lasted for 1 h. We prolonged the period and investigated how quickly can induce respiratory systemic effects. Eighteen healthy volunteers were exposed twice diluted (PM1 ~300 μg/m3) filtered air ~2 3 h, seated, in chamber with double-blind set-up. Immediately before after exposure, we performed medical examination, spirometry, rhinometry, nasal...
Particle number (PN) concentrations (10-300 nm in size) were continuously measured over a period of ~45 h 56 residences nonsmokers Copenhagen, Denmark. The highest when occupants present and awake (geometric mean, GM: 22.3 × 10(3) cm(-3)), the lowest homes vacant (GM: 6.1 cm(-3)) or asleep 5.1 cm(-3)). Diary entries regarding occupancy particle related activities used to identify source events apportion daily integrated exposure among sources. Source clearly resulted increased PN decreased...
Several diesel exhaust (DE) characteristics, comprising both particle and gas phase, recognized as important when linking with health effects, are not reported in human chamber exposure studies. In order to understand effects of DE on humans there is a need for better characterization performing The aim this study was determine quantify detailed characteristics during exposure. Additionally compare properties conducted exposures. A wide battery phase measurement techniques have been used...
Poor air quality is a leading contributor to the global disease burden and total number of deaths worldwide. Humans spend most their time in built environments where majority inhalation exposure occurs. Indoor Air Quality (IAQ) challenged by outdoor pollution entering indoors through ventilation infiltration indoor emission sources. The aim this study was understand current knowledge level gaps regarding effective approaches improve IAQ. Emission regulations currently focus on emissions,...
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....
Background:Exposure to fine particles is associated with respiratory disease, cardiovascular disease and mortality. Recent studies advocate that ultrafine (UFP) may be of concern regarding adverse health effects. The contribution indoor sources the overall UFP exposure can substantial. Aims:This work aims characterize UFP, identify activities responsible for exposure, estimate source events total occupants. Methods:Particle number concentrations (PN; 10 - 300 nm in size) were continuously...
Exposure to ambient air particulate matter (PM) has been linked decline in pulmonary function and cardiovascular events possibly through inflammation. Little is known about individual exposure ultrafine particles (UFP) inside outside modern homes associated health-related effects. Associations between vascular lung function, inflammation markers terms of particle number concentration (PNC; d = 10-300 nm) were studied a cross-sectional design with personal home indoor monitoring the Western...
Phthalates are ubiquitous in indoor environments, which raises concern about their endocrine-disrupting properties. However, studies of human uptake from airborne exposure limited. We studied the inhalation and dermal by air-to-skin transfer with clean clothing as a barrier two deuterium-labeled phthalates: particle-phase D4-DEHP (di(2-ethylhexyl)phthalate) gas-phase D4-DEP (diethyl phthalate). Sixteen participants, wearing trousers long-sleeved shirts, were under controlled conditions...
Particulate air pollution increases risk of cancer and cardiopulmonary disease, partly through oxidative stress. Traffic-related noise cardiovascular disease may cause In this controlled random sequence study, 18 healthy subjects were exposed for 3h to diesel exhaust (DE) at 276 μg/m(3) from a passenger car or filtered air, with co-exposure traffic 48 75 dB(A). Gene expression markers inflammation, (interleukin-8 tumor necrosis factor), stress (heme oxygenase (decycling-1)) DNA repair...
Indoor environments have a large impact on health and well-being, so it is important to understand what makes them healthy sustainable. There substantial knowledge individual factors their effects, though understanding how interact role occupants play in these interactions (both causative receptive) lacking. We aimed to: (i) explore between potential risks if are not considered from holistic perspective; (ii) identify components needed advance research indoor environments. The paper based...
