Major explosive volcanic eruptions may significantly alter the global atmosphere for about 2–3 years. During that period, products (mainly H2SO4) with high residence time, stored in stratosphere or, shorter times, troposphere are gradually deposited onto polar ice caps. Antarctic snow thus record acidic signals providing a history of past events. The resolution sulphate concentration profile along 197 m long core drilled at GV7 (Northern Victoria land) was obtained by Ion Chromatography on...
To fight counterfeits and to protect the consumer, interest in certifying origin of agricultural goods has been steadily growing last years. While numerous works focus on finished product, an aspect often overlooked is raw materials direct correlation between chemicals soil plants. With inductively coupled plasma mass spectrometry (ICP-MS) analysis, trace ultratrace elements Sangiovese grapes (the main component Chianti wine) were measured their levels used investigate geographical samples....
While more and studies are being conducted on carbonaceous fractions—organic carbon (OC) elemental (EC)—in urban areas, there still too few about these species their effects in polar areas due to very low concentrations; further, the literature report only data from intensive campaigns, limited time. We present here for first time EC–OC concentration long-time records sea-level sampling site of Ny-Ålesund, High Arctic (5 years), Dome C, East Antarctic Plateau (1 year). Regarding Arctic,...
Starting from 1952 C.E. more than 540 atmospheric nuclear weapons tests (NWT) were conducted in different locations of the Earth. This lead to injection about 2.8 t 239Pu environment, roughly corresponding a total radioactivity 6.5 PBq. A semiquantitative ICP-MS method was used measure this isotope an ice core drilled Dome C (East Antarctica). The age scale for studied work built by searching well-known volcanic signatures and synchronising these sulfate spikes with established chronologies....
To fight counterfeits, and to protect the consumer, interest in certifying origin of agricultural goods has been growing recent years. In this context increase accuracy zoning models, multiple analytical techniques must be combined via a multivariate approach. During sampling campaign, leaves fruits (olives or drupes) were collected from orchards farms. By means HPLC-DAD, metabolite levels evaluated with trace ultra-trace metal/metalloid by ICP-MS (QqQ). The dataset was then used develop...
Abstract. As part of the “East Antarctic International Ice Sheet Traverse” (EAIIST) project, surface snow and pit samples were collected along a traverse from Dome C toward geographic South Pole during 2019–2020 campaign. Results on spatial distribution major ions are here reported to understand deposition post processes in sites with very low accumulation rate East Plateau where megadune wind crust areas present. The volcanic signature Pinatubo eruption (occurred 1991) was clearly visible...
Abstract. Ice core dating is the first step for a correct interpretation of climatic and environmental changes. In this work, we release uppermost 197 m 250 deep GV7(B) ice (drill site, 70∘41′ S, 158∘52′ E; 1950 a.s.l. in Oates Land, East Antarctica) with sub-annual resolution. Chemical records NO3-, MSA (methanesulfonic acid), non-sea-salt SO42- (nssSO42-), sea-salt ions water stable isotopes (δ18O) were studied as candidates due to their seasonal pattern. Different procedures tested but...
Abstract. Ice core dating is the first step for a correct interpretation of climatic and environmental changes. In this work, we release stratigraphic uppermost 197 m 250 deep GV7(B) ice (drilling site, 70°41’S, 158°52’E, 1950 a.s.l.) with sub-annual resolution. Chemical stratigraphies NO3−, MSA (methanesulfonic acid), non-sea salt SO42−, sea-salt ions oxygen isotopic composition (δ18O) were used in annual layer counting upon identification seasonal profile their records. Different...
The study of aerosol chemical composition in the Antarctic plateau can provide basic information on main natural (and also anthropogenic) inputs, atmospheric reactivity, and long-range transport processes components. Moreover, physical occurring at atmosphere-snow interface are yet not fully understood work is needed to assess impact chemistry snow better interpret ice core records retrieved those sites.At this purpose, simultaneous surface samplings were set up run Dome C station...
<p>Explosive volcanic eruptions are able to affect significantly the atmosphere for 2‐3 years. During this time, products (mainly H2SO4) with high residence 
time stored in stratosphere/troposphere, and eventually deposited onto polar ice caps; snow layers may thus record signals providing a history of past 
volcanic events. A resolution sulphate concentration profile along 197 m long core drilled at GV7 (Northern Victoria Land) was...
