Correlation between magnetic parameters and chemical composition of lake sediments from northern Bohemia—Preliminary study

Abstract

Abstract.Recently, magnetic measurements have been used m outline areas with increased loading of toxic metals due to industrial activity. It is supposed that magnetic minerals, which are easily detectable, can cant toxic metals of anthropic origin. However, physical background of this relationship is not comprehended yet. In this study, we present our first results on statistical correlation of various magnetic parameters on one side and chemical composition on the other, obtained on sediments from the bottom of lake Nechranice, located in noRhern Bohemia; the captive area being typical for intensive industrial and mining activity (brown-coal basins, uranium mines, coalburning power plants). Our results suggest, that magnetic susceptibility, which has been used in other studies as indicator of increase pollution levels due to local sources, does not actually link to any of the toxic elements in concern. This finding can be explained in terms of complex inlet due to different types of pollution sources.

Use of mineral magnetic concentration data as a particle size proxy: A case study using marine, estuarine and fluvial sediments in the Carmarthen Bay area, South Wales, U.K.

“…Arkell et al, 1983;Oldfield et al, 1985White et al, 1997;Walden et al, 1995Walden et al, , 1997Schmidt et al, 1999;Wheeler et al, 1999). Many of the studies have explored the relationship between mineral magnetic measurements and chemical/physical properties of sediments and soils (Oldfield et al, 1985;Oldfield and Yu, 1994;Clifton et al, 1997Clifton et al, , 1999Chan et al, 1998;Petrovsky et al, 1998;Xie et al, 1999Xie et al, , 2000Booth, 2002). Based on these investigations, mineral magnetic measurements have been identified as a suitable tool for determining sediment provenance (Oldfield and Yu, 1994;Booth, 2002), sediment transport pathways (Lepland and Stevens, 1996), and also to serve as a proxy for geochemical, radioactivity, organic matter content and particle size data (Bonnett et al, 1988;Oldfield et al, 1993;Hutchinson and Prandle, 1994;Clifton et al, 1997Clifton et al, , 1999Xie et al, 1999Xie et al, , 2000Zhang et al, 2001).…”

Magnetic properties and heavy metal contents of automobile emission particulates

“…In recent years magnetic measurements, which are simple, rapid, inexpensive, and nondestructive, are increasingly being used in a wide range of environmental sciences such as identification of source of industrial pollutants and atmospheric particulates (Hunt et al, 1984;Kapicka et al, 2003;Lecoanet et al, 2003;Moreno et al, 2003;Shu et al, 2001), mapping of soils and sediments pollution (Hanesch et al, 2003;Hoffmann et al, 1999;Matzka and Maher, 1999), and a proxy parameter for quantifying contents of heavy metals in certain environments (Chan et al, 2001;Petrovsky et al, 1998;2000). Many works on soils, sediments and atmospheric dusts have shown that the magnetic properties of airborne particles, industrially polluted soils and sediments were strongly associated with heavy metal concentration and mutagenic organic compounds (Hunt et al, 1984;Lecoanet et al, 2003;Morris et al, 1995).…”

The Application of Environmental Magnetism Techniques for Pollution Assessment in Urban and Suburban Areas in Greece: State of the Art and Case Studies

“…For obvious reasons magnetic methods can be used for the characterisation of pollution and have become commonplace by many international laboratories (e.g. Dearing et al, 1996;Petrovsky et al, 1998;Evans & Heller, 2003;Hanesch et al, 2003).…”
