Abstract. The widespread use of Aerodyne aerosol mass spectrometers (AMS) has greatly improved real-time organic (OA) monitoring, providing spectra that contain sufficient information for source apportionment. However, AMS field deployments remain expensive and demanding, limiting the acquisition long-term datasets at many sampling sites. offline application spectrometry entailing analysis nebulized water extracted filter samples (offline-AMS) increases spatial coverage accessible to...
This study addresses the pressing issue of black carbon (BC) pollution in urban areas, focusing on two locations Philippines: Quezon City’s East Avenue (QCG, roadside environment) and Manila’s North Port. We found that organic aerosol particles (OA) made a greater contribution (80%) to total submicron particulate matter compared inorganic (IA) (20%). The mean hourly average equivalent (eBC) mass concentration at QCG site (35.97 ± 16.20 𝜇g/m3) was noticeably higher Port (10.27 5.99 𝜇g/m3),...
Abstract. In early spring the Baltic region is frequently affected by high-pollution events due to biomass burning in that area. Here we present a comprehensive study investigate impact of biomass/grass (BB) on evolution and composition aerosol Preila, Lithuania, during springtime open fires. Non-refractory submicron particulate matter (NR-PM1) was measured an Aerodyne chemical speciation monitor (ACSM) source apportionment with multilinear engine (ME-2) running positive matrix factorization...
The process of nanoparticle generation during nanosecond and picosecond laser ablation various metals (Ni, Al, W, stainless steel) in ambient air argon gas was investigated.The number concentration nanoparticles generated by up to 100 times higher compared that air.Three stable separate size peaks nucleation, Aitken, accumulation modes were observed case gas, while particles a wide spectrum (8-200 nm) generated.The natural precursors can have an effect on the composed chemical compounds with...
The natural processes of interactions between aerosol particles in the ambient air through which they agglomerate is a vast area chamber research and are inherent to many industries often inter-connected with transport engineering. Further improvement symmetric methods for particle number mass concentration reduction made it possible create various synergic techniques. study used 1.9 TDI diesel internal combustion engine, was supplied (D100) second-generation biofuels (NExBTL100) EGR exhaust...
Abstract Atmospheric new particle formation (NPF) is a naturally occurring phenomenon, during which high concentrations of sub-10 nm particles are created through gas to conversion. The NPF observed in multiple environments around the world. Although it has observable influence onto annual total and ultrafine number (PNC UFP, respectively), only limited epidemiological studies have investigated whether these associated with adverse health effects. One plausible reason for this limitation may...
While the impacts of climate change on wildfires and resulting air pollution levels have been observed, little is known about how indoor filtering systems are performing under intensive smoke conditions. For this aim, particle number size distribution concentration in a range 0.5–18 µm equivalent black carbon (eBC) mass were measured modern office with mechanical ventilation system. Measurements took place from 30 September to 6 October 2020 Center for Physical Sciences Technology (FTMC)...
The present study investigated the characteristics of carbonaceous species in an urban background site. Real-time measurements inorganic (sulfate, nitrate, ammonium, chloride, and black carbon [BC]) organic submicron aerosols (OA) were carried out at site Vilnius, Lithuania, during January–February 2014. An aerosol chemical speciation monitor (ACSM, Aerodyne Research Inc., Billerica, MA, USA) co-located 7-λ aethalometer (AE-31, Magee Scientific, Berkeley, CA, used to analyze compositions,...
In situ investigation results of aerosol optical properties (absorption and scattering) chemical composition at an urban background site in Lithuania (Vilnius) are presented. Investigation was performed May-June 2017 using speciation monitor (ACSM), a 7-wavelength Aethalometer 3-wavelength integrating Nephelometer. A positive matrix factorisation (PMF) used for the organic mass spectra analysis to characterise sources ambient (OA). Five OA factors were identified: hydrocarbon-like (HOA),...
