Abstract. Ultrafine particles (UFPs) have aerodynamic diameters of 100 nm or less. As UFPs potentially impact human and environmental health, their chemical composition is interest. However, small mass presents challenges for sampling characterization methods. Therefore, we conducted a comprehensive comparison four cascade impactors suitable separating collecting – namely, the 120R Micro-Orifice Uniform Deposit Impactor (120R MOUDI-II), ultraMOUDI, electrical low-pressure impactor (ELPI),...
Ultrafine particles (UFP) are the smallest atmospheric particulate matter linked to air pollution-related diseases. The extent which UFP's physical and chemical properties contribute its toxicity remains unclear. It is hypothesized that UFP act as carriers for chemicals drive biological responses. This study explores robust methods generating reference understand these mechanisms perform toxicological tests. Two types of combustion-related with similar elemental carbon cores but different...
Pollen related allergic diseases have been increasing for decades. The reasons this increase are unknown, but environmental pollution like diesel exhaust seem to play a role. While previous studies explored the effects of pollen extracts, we studied here first time priming on native exposure using novel experimental setup. Human bronchial epithelial BEAS-2B cells were exposed birch (real life intact pollen, not extracts) at air-liquid interface (pollen-ALI). also pre-exposed in diesel-ALI...
Ship emissions are a major cause of global air pollution, and in particular, from the combustion bunker fuels, such as heavy fuel oil (HFO), show strong impacts on environment human health. Therefore, sophisticated measurement techniques needed for monitoring. We present here an approach to remotely investigating ship exhaust plumes through onboard measurements research vessel Baltic Sea. The were detected distance ~5 km by rapid changes particle number concentration variation ambient size...
Agricultural fires are a major source of biomass-burning organic aerosols (BBOAs) with impacts on health, the environment, and climate. In this study, globally relevant BBOA emissions from combustion sugar cane in both field laboratory experiments were analyzed using comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry. The derived chemical fingerprints fresh evaluated targeted nontargeted evaluation approaches. open-field burning revealed high complexity...
Emissions from road traffic and residential heating contribute to urban air pollution. Advances in emission reduction technologies may alter the composition of emissions affect their fate during atmospheric processing. Here, a gasoline car wood stove, both equipped with modern mitigation technology, were photochemically aged an oxidation flow reactor equivalent one five days photochemical aging. Fresh exhausts analyzed by ultrahigh resolution mass spectrometry. The three-way catalyst...
Abstract The combustion of petroleum-based fossil fuels is associated with a high environmental burden. Several alternative fuels, including synthetic (e.g., gas-to-liquid, GTL) and biofuels rapeseed methyl ester, RME) have been studied in the last few years. While advantages for environment (sustainability biofuels) are well known, research on resulting health effects from aerosols these still scarce. Consequently, we investigated chemical profile three distinct fuel types, (B0) two (GTL,...
Abstract. Ultrafine particles (UFP) have aerodynamic diameters of 100 nm or less. As UFP potentially impact human and environmental health, their chemical composition is interest. However, small mass presents challenges to techniques originally developed for larger particles. Therefore, we conducted a comprehensive characterization comparison four cascade impactors suitable separate collect UFP, namely 120R MOUDI (Micro-Orifice Uniform Deposit Impactor), ultraMOUDI, ELPI (Electrical...
Abstract The prevalence of allergic diseases is constantly increasing since few decades. Anthropogenic ultrafine particles (UFPs) and allergenic aerosols highly involved in this increase; however, the underlying cellular mechanisms are not yet understood. Studies observing these effects focused mainly on singular vivo or vitro exposures single particle sources, while there only limited evidence their subsequent combined effects. Our study aimed at evaluating effect to allergy‐related...
Abstract Allergic diseases are an increasing global burden. Epidemiological and in vivo studies showed that farming environments could protect from allergic asthma. Studies explaining this protective effect mainly focused on the influence of chemical compounds molecular size range proteins endotoxins. Our study aimed at deciphering possible role small-sized semi-volatile organic (SVOCs) aerosols immunomodulation processes. Bronchial epithelial BEAS-2B cells were exposed to aerosol extracts...
