Radioactive emissions into the atmosphere from damaged reactors of Fukushima Dai-ichi nuclear power plant (NPP) started on March 12th, 2011. Among various radionuclides released, iodine-131 ((131)I) and cesium isotopes ((137)Cs (134)Cs) were transported across Pacific toward North American continent reached Europe despite dispersion washout along route contaminated air masses. In Europe, first signs releases detected 7 days later while peak activity level was observed between 28th 30th. Time...
In this paper we present a study on stratospheric intrusion (SI) events recorded at high mountain station in the Italian northern Apennines. Six years (1998–2003) of surface ozone and beryllium‐7 concentration measurements as well relative humidity values GAW Mt. Cimone research (44°11′N, 10°42′E; 2165 m asl) were analyzed. Moreover, three‐dimensional backward trajectories calculated by FLEXTRA model potential vorticity along these used. order to identify SI evaluate their contribution...
Vulsini Volcanic district in Northern Latium (Central Italy) is characterized by high natural radiation background resulting from the concentrations of uranium, thorium and potassium volcanic products. In order to estimate radon risk, a series soil gas measurements were carried out Bolsena, principal urban settlement this area NE Rome. Soil concentration ranges between 7 176 kBq/m(3) indicating large degree variability NORM content behavior parent material related particular occurrence two...
This study investigates the major chemical components, particle-bound water content, acidity (pH), and potential sources of PM2.5 in cities (Belluno, Conegliano, Vicenza, Mestre, Padua, Rovigo) eastern end Po Valley. The measured mass was reconstructed using a multiple-site hybrid closure approach that also accounts for aerosol inorganic content (AWC) estimated by ISORROPIA-II model. Annually, organic matter accounted 31-45% at all sites, followed nitrate (10-19%), crustal material (10-14%),...
We discuss remote terrestrial influences on boundary layer air over the Southern Ocean and Antarctica, mechanisms by which they arise, using atmospheric radon observations as a proxy. Our primary motivation was to enhance scientific community's ability understand quantify potential effects of pollution, nutrient or pollen transport from distant land masses these remote, sparsely-instrumented regions. Seasonal characteristics are discussed at 6 stations (Macquarie Island, King Sejong,...
Low-cost sensors based on the optical particle counter (OPC) are increasingly being used to collect particulate matter (PM) data at high space and time resolution. In spite of their huge explorative potential, practical guidelines recommendations for use still limited. this work, we outline a few best practices optimal PM low-cost results an intensive field campaign performed in Bologna (44°30' N, 11°21' E; Italy) under different weather conditions. Briefly, performances series were...
Abstract This work highlights the importance of Geogenic Radon Potential (GRP) component originated by degassing processes in fault zones. Tectonically Enhanced (TER) can increase radon concentration soil gas and inflow buildings (Indoor Concentrations, IRC). Although tectonically related enhancement is known areas characterised active faults, few studies have investigated migration non-active The Pusteria Valley (Bolzano, north-eastern Italy) represents an ideal geological setting to study...
During the EU‐project Influence of Stratosphere‐Troposphere exchange in a Changing Climate on Atmospheric Transport and Oxidation Capacity (STACCATO), combined approach measurement network numerical simulations was used to estimate strength frequency stratosphere‐to‐troposphere transport (STT) events their influence tropospheric chemistry. Measurements surface ozone, beryllium‐7, beryllium‐10 concentrations meteorological parameters at four European high mountain stations, as well...
Simultaneous measurements of 7 Be and 210 Pb the analyses activity ratio, i.e., Be/ Pb, offer another useful analytical tool for improving our understanding ozone variability occurring at high altitude because they can provide diagnostic indicators horizontal vertical transport processes. Generally, increase (decrease) with decrease (increase) in association (low) values indicates mechanisms associated (for being favorable to horizontal) For purpose demonstrating these transport, we have...
The Mediterranean basin represents a hot spot area for short-term O3 distribution and anthropogenic contributions to it. This is why we analysed in this work the surface variability observed at Mt. Cimone WMO/GAW global station (CMN, 44°12′ N, 10°42′ E, 2165 m a.s.l., Italy) from 1991 2011. measurements performed mountain observatory represent longest record baseline site basin. Monthly averages CMN show typical seasonal cycle characterised by winter minimum spring – summer maxima. shape of...
Abstract The Ross Sea is an area of dense water formation within the Southern Ocean, hence it potentially plays important role for anthropogenic CO 2 sequestration . In order to estimate penetration carbon in from total inorganic (TCO ) measurements carried out 2002–03 Antarctic Italian Expedition, we applied two independent models. Anthropogenic was present throughout column. highest concentrations were associated with recently ventilated shelf waters, namely High Salinity Shelf Water...
Abstract. We apply the Global Modeling Initiative (GMI) chemistry and transport model driven by NASA's MERRA assimilated meteorological data to simulate seasonal variations in two radionuclide aerosol tracers (terrigenous 210Pb cosmogenic 7Be) at WMO-GAW station of Mt. Cimone (44°12′ N, 10°42′ E; 2165 m a.s.l.; Italy), which is representative free-tropospheric conditions most year, during 2005 with an aim understand roles precipitation scavenging processes controlling their seasonality. The...
Abstract. This paper concerns an in-depth analysis of exceptional incursion mineral dust over southern Europe in late March 2020 (27–30 2020). event was associated with anomalous circulation pattern leading to several days PM10 (particulate matter aerodynamic diameter less than 10 µm) exceedances connection a source located central Asia; this is rare for Europe, which more frequently affected by outbreaks from the Sahara Desert. The synoptic meteorological configuration analyzed detail, and...
The evaluation of the sources particulate matter (PM) is one most important topics in environmental science. Both natural and anthropogenic are involved overall PM pollution both urban rural areas. Mathematical methods, as Positive Matrix Factorization (PMF), applied to chemical data powerful tools for discrimination sources.In present work, results obtained from a three-year sampling campaign (between 2017 2019) presented. 700 PM10 filters were collected framework FRESA Project (Impact...
