Microplastics and nanoplastics have been reported in nearly all environmental compartments, the dataset about their contributions role as a sink carrier for other hydrophobic compounds atmosphere however is limited. This study presents, first time, atmospheric concentrations of ultrafine microplastics (UFMNP) on single polymer level correlations with 23 polycyclic aromatic hydrocarbons (PAHs). Measurements UFMNP ambient particulate matter (PM2.5) were performed an urban sampling site Graz,...
Residential wood combustion is, besides particulate emissions, also linked to emissions of organic compounds, comprising various toxic substances such as polycyclic aromatic hydrocarbons (PAHs). Although, literature data has shown that highest occur during maloperations caused by the user itself, most studies focus on lab-testing not reflecting situation in field. This study evaluates real-life Austria, investigating total suspended particles (TSP) and particle-bound four manually operated...
During spring 2020, unprecedented changes in local and regional emissions have occurred around the globe due to governmental restrictions associated with COVID-19. Many European countries including Austria issued partial curfews or stay-at-home order policies, which impacted ambient air quality through reductions non-essential transportation energy consumption of industrial sites work places. Here, we analyse effect these measures on concentrations nitrogen oxides (NOx), ozone (O3)...
In early 2017 high particulate matter (PM) levels were observed across mid-Europe, including Austria. Here we characterize PM pollution in the city of Graz during January to March 2017, a period with substantial exceedances (34 days) European Union (EU) PM10 short time limit value. This study evaluates whether can be attributed accumulation pollutants emitted by local sources or larger scale episode transport. The analyses are based on ratios concentrations determined at an urban and...
Organic matter in ice cores holds important climatic information, such as the prevalence of wildfires, marine algae blooms, terrestrial biosphere productivity, and antarctic sea extent. While organic compounds are specific tracers paleoclimatic records, very little is known about their transport deposition onto glaciers sheets. Factors atmospheric transport, scavenging atmosphere efficiency can have a substantial effect on amount measured snow ice. To better understand sheets, we determined...
Emissions from wood-burning stoves contribute to local air pollution. However, it is difficult determine the real emissions such stoves, especially due unknown user behaviour, which can have a large impact on emissions. In this study, low-cost emission reduction measure "user training" was evaluated its potential firewood stoves. Two sets of tests were carried out. First, field measurement campaign conducted in Styria (Austria) with four wood where gaseous and particulate measured before...
Biomass combustion is a major contributor to ambient air pollution.Thus, knowing the real-life emissions of biomass heating systems crucial.Within project Clean Air by field measurement campaign was conducted.15 appliances were tested in households at end user according their usual operation.Emission factors for gaseous and particulate emissions, as well genotoxic carcinogenic substance benzo(a)pyrene, evaluated compared current proposed European Austrian emission used inventories.Moreover,...
Abstract. The determination of mineral dust and elemental carbon in snow samples is great interest, since both compounds are known to be light-absorbing impurities. Different analytical methods have used quantify compounds. occurrence dust, which contains hematite, leads a bias the quantification organic via thermal–optical analysis. Here we present an approach utilizes this interference determine concentration iron analysis using Lab OC / EC Aerosol Analyzer (Sunset Laboratory Inc.) EUSAAR2...
Polycyclic Aromatic Hydrocarbons (PAHs) in the ambient particulate matter pose one of most important issues focus environmental management. The concentration their representative, Benzo(a)pyrene (BaP), undergoes limitations according to European Union directive. However, a successful control over pollution levels and sources is limited by high uncertainty analytical statistical approaches used for characterization. Here we compare differences PAH concentrations related use different solvents...
Measurements of ultrafine microplastics and nanoplastics (UFMNP) on the single polymer level in ambient particulate matter (PM 2.5 ) were performed for an urban sampling site Graz, Austria. During period 02.01. – 31.03.2017 average UFMNP concentration was 238 ng/m 3 , reaching up to 557 . This accounts contribution 0.67% PM mass 1.7% organic matter. The individual types polyethylene terephthalate (PET), polypropylene (PP) (PE), which sum most demanded Europe. PET found be prominent samples...
