Fast and cost-effective detection of industrial pollution can significantly promote its ecological, economic, social assessment. A magnetometric method, used for qualitative determination anthropogenic contamination, meets these requirements but needs further development in more quantitative terms. It could be successfully numerous cases when the heavy metals coexist with strongly magnetic iron oxide particles source dust. We present an integrated geochemical study that examines utility...
Abstract. The global character of the millennial-scale climate variability associated with Dansgaard–Oeschger (DO) events in Greenland has been well-established for last glacial cycle. Mainly due to sparsity reliable data, however, spatial coherence corresponding during penultimate cycle is less clear. New investigations European loess records from Marine Isotope Stage (MIS) 6 reveal occurrence alternating intervals and paleosols (incipient soil horizons), similar those climatic These are...
The Campi Flegrei (CF) caldera, in southern Italy, is the source of some most powerful Late Pleistocene eruptions European sub-continent (e.g., Campanian Ignimbrite, Neapolitan Yellow Tuff eruptions). Although CF caldera has been continuously and intensively investigated for decades, relatively little known regarding its earliest volcanic activity. In this work, integrating existing new tephrostratigraphic data, we provide a comprehensive updated framework activity which occurred at ∼160 ka...
Settled indoor and outdoor dusts in urban environment represent an important source of secondary pollution. Magnetic characteristics the settled dust from six cities Bulgaria are explored, allowing comparison on a national (country) scale. Monthly variations mass‐specific magnetic susceptibilities ( χ ) calculated loading rates for period 17 months do not show seasonal variability, probably due to dominant role traffic‐related emissions soil‐derived particles dust. The main mineral is...
Thermomagnetic analysis of magnetic susceptibility k(T) was carried out for a number natural powder materials from soils, baked clay and anthropogenic dust samples using fast (11oC/min) slow (6.5oC/min) heating rates available in the furnace Kappabridge KLY2 (Agico). Based on additional data mineralogy, grain size properties studied samples, behaviour cycles observed differences curves rate are interpreted terms mineralogical transformations Curie temperatures (Tc). The effect different...
Loess-palaeosol deposits in the lower Danube area represent southeastern edge of loess cover Europe. Detailed rock magnetic investigations loess/palaeosol sequence Viatovo NE Bulgaria reveal that magnetite and maghemite very fine superparamagnetic grain size are responsible for enhancement palaeosol units. A detailed palaeoclimatic record is obtained through high-resolution measurements susceptibility, frequency dependent susceptibility CaCO3 content. Magnetic proxies indicate a more warm...
