Mineral magnetic characterization of anthropogenic magnetic phases in the Danube river sediments (Bulgarian part)☆

Variations in the Concentration of Magnetic Minerals and Heavy Metals in Suspended Sediments from Citarum River and Its Tributaries, West Java, Indonesia

“…We propose that future studies might consider using the ratio of SIRM/χLF to distinguish the anthropogenic origin in river sediments. [8,27,28,33,34]. This situation differs significantly with the reported values in the rivers from a temperate climate and non-volcanic areas [28,29,33].…”

“…In general, these Fe and Ti contents were relatively higher than those of the report in the literature for other rivers (Fe in [8,9,28,29,[32][33][34], and Ti in [32,33]). Moreover, the Fe contents in the suspended sediment samples exceeded the environmental safety threshold, which is 20 mg/kg according to [35].…”

“…generally higher than that of Citarum River samples. An earlier study used the SIRM/χLF ratio merely to infer the type of magnetic minerals in the river sediment [33]. However, there is a possibility that in our study this ratio might also differentiate samples that are predominantly lithogenic in origin (relatively low SIRM/χLF ratio) from those that are predominantly anthropogenic in origin (high SIRM/χLF ratio).…”

Magnetic, chemical and radionuclide studies of river sediments and their variation with different physiographic regions of Bharathapuzha river, southwestern India

“…Magnetic iii parameters have been widely used in environmental magnetism and some of them have been proven to be good proxies for environmental changes and contamination. Thus, magnetic proxies allow rivers to be assessed for reduced or wide extensions using the bed sediments (e.g., Scholger, 1998;Magiera et al, 2002;Jordanova et al, 2004;Desenfant et al, 2004;Chaparro et al, 2004Chaparro et al, , 2008Chaparro et al, , 2013Knab et al, 2006;Yang et al, 2007;Franke et al, 2009;Zhang et al, 2011;Sandeep et al, 2011).…”

Magnetic susceptibility as a tool for the discrimination of anthropogenic and lithogenic history of topsoils: preliminary results from the broader area of Thessaloniki city.

“…Thompson and Oldfield (1986) reported that soils near urban and industrial areas have an increased magnetic susceptibility, representative of the deposition of magnetic particles, such as, dusts of industries and fly ashes of the coal combustion. Moreover, magnetic susceptibility mapping was successfully applied in different countries for the estimation of anthropogenic pollution (Strzyszcz, 1993;Dearing et al, 1996;Scholger, 1998;Petrovsky et al, 1998Petrovsky et al, , 2000Kapicka et al, 2001;Lecoanet et al, 2001;Boyko et al, 2004;Jordanova et al, 2004;Lu and Bai, 2006;Magiera et al, 2006). Despite this big development especially in Europe, in Greece only few studies have been performed during the last decades (Scoullos et al, 1979, Sarris et al, 2009, Zananiri et al, 2010.…”
