“…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).…”

Compositional (non-magnetic) data can correlate strongly with particle size, which deems it appropriate as a particle size proxy and, therefore, a reliable means of normalising analytical data for particle size effects. Previous studies suggest magnetic concentration parameters represent an alternative means of normalising for these effects and, given the speed, low-cost and sensitivity of the measurements may, therefore, offer some advantages over other compositional signals. In this work, contemporary sediments from a range of depositional environments have been analysed with regard to their mineral magnetic concentration and textural characteristics, to observe if the strength and nature of the relationship identified in previous studies is universal. Our data shows magnetic parameters (v LF , v ARM and SIRM) possess contrasting relationships with standard textural parameters for sediment samples collected from marine (Carmarthen Bay), estuarine (Gwendraeth Estuary) and fluvial (Rivers Gwendraeth Fach and Gwendraeth Fawr) settings. Magnetic concentrations of sediments from both the marine and estuarine environments are highly influenced by the magnetic contribution of finer particle sizes; Gwendraeth Fawr River sediments are influenced by the magnetic contribution of coarser particle sizes, while sediments from the Gwendraeth Fach River are not influenced significantly by any variations in textural properties. These results indicate mineral magnetic measurements have considerable potential as a particle size proxy for particular sedimentary environments, which in certain instances could be useful for geochemical, sediment transport, and sediment provenance studies. However, the data also highlight the importance of fully determining the nature of the relationship between sediment particle size and magnetic properties before applying mineral magnetic data as a particle size proxy.

“…In the solute form, these metals show similar chemical properties and have a tendency to co-precipitate with hydrous oxides of Fe and Mn (Chan et al, 1998;Wang and Qin, 2005). On the other hand, no correlations were observed between MS and Cr (R=0.17, p<0.05) and Pb (R=-0.20, p<0.05).…”

“…Up to now, magnetic susceptibility measurements have been widely used to evaluate the spatial distribution of pollutants (Lu et al, 2008) in the upper layers of soil in industrial areas (Blundell et al, 2009;Duan et al, 2010), close to roads (Baghdadi et al, 2011;Wawer et al, 2015), and in marine and river sediments (Chan et al, 1998;Chaparro et al, 2011;Prajith et al, 2015;Zan et al, 2015). Several studies showed a strong correlation between magnetic parameters and the content of heavy metals (Karimi et al, 2011;Ma et al, 2015;Rosowiecka and Nawrocki, 2010;Strzyszcz and Magiera, 1998).…”

A b s t r a c t. In this work, we attempted to analyse the changes in magnetic susceptibility in Terric Histosol soil irrigated with municipal wastewater in a period of four years. Effects of different plants (poplar and willow), wastewater doses, depths, as well as the concentration of the elements and the total carbon content were tested. The study showed that systematic wastewater irrigation diminished magnetic susceptibility values in the top layer of soil. However, statistical analysis revealed that both doses of wastewater and growing plants did not have a significant impact on the magnetic susceptibility of obtained results. Magnetic susceptibility decreased significantly with the depth, in accordance with higher total carbon and lower content of magnetic particles. High correlation coefficients were found between magnetic susceptibility

“…It appears that atmospheric deposition is one of the major sources of contamination in coastal and marine sediments (Chan et al 1998(Chan et al , 2001Alagarsamy 2009;Horng et al 2009;Canbay et al 2010). The high magnetic susceptibility observed in marine sediments could result from different mechanisms, such as diagenetic changes in magnetic mineralogy (Karlin et al 1987), fine grained iron oxides derived from anthropogenic sources (Chan et al 2001), an increased input of detrital magnetite from soil erosion (Maher and Taylor 1988;Higgitt et al 1991), high concentration of magnetotactic bacteria in marine sediment (Lovley et al 1987).…”

Environmental magnetic and geochemical characteristics of Chennai coastal sediments, Bay of Bengal, India

In this study, environmental magnetic, heavy metal and statistical analyses were conducted on 21 surface sediments collected from Chennai coast, India, to examine the feasibility of heavy metal pollution using magnetic susceptibility. The Chennai coastal sediment samples are dominated by ferrimagnetic minerals corresponding to magnetite-like minerals. The percentage of frequency dependent magnetic susceptibility reflects the presence of super-paramagnetic/single domain magnetic minerals in Chennai harbour, Cooum and Adayar rivers sediments. High pollution load index in sample E1, E2, CH7, C11, C12 and A16 is mainly due to anthropogenic activities such as, harbour activities, Cooum and Adayar rivers input and industrial effluent. Factor analysis shows that the magnetic concentration dependent parameters (χ, χ ARM and SIRM) covary with the heavy metal concentrations, suggesting that the input of magnetic minerals and heavy metals in Chennai coastal sediments are derived from the same anthropogenic sources. Strong correlation obtained between pollution load index (PLI) and concentration dependent parameters (χ, χ ARM and SIRM) for the polluted samples with magnetic susceptibility excess of 50×10 −8 m 3 kg −1 . Significant correlations between heavy metals and magnetic susceptibility point out the potential of magnetic screening/monitoring for simple and rapid proxy indicator of heavy metal pollution in marine sediments.
