“…There was no correlation between lead concentrations in sediments and in mussels at these stations. This is consistent with previous studies (HORNUNG, 1989;HORNUNG et al, 1989) that have shown no relationship between the lead concentrations in mollusc bivalvia, gastropods and in sediments. However, at St. 1, high concentrations in mussels and sediments coincided and it is assumed that the high lead content of mussels at this station is related not only to the high concentrations in sediments but also to other sources such as phytoplankton.…”

Lead pollution and its sources have been investigated in the south-eastern and south-western Black Sea. Surficial sediments and mussels were collected in different seasons of the year from the south-eastern and south-western Black Sea and analysed for their lead contents.In the south-eastern Black Sea sediments from the easternmost and from the central stations contained the highest lead concentrations. Sediments contained 8 to 10 times the lead concentrations of sediments from the south-west. Samples taken from rivers, streams and effluents had especially high lead concentrations. The highest lead concentrations were found in sediments collected in October and December.Lead concentrations in mussels from the south-eastern coast were comparatively lower compared to those from the south-western coast. The highest average values occurred in December and in October.In the south-western Black Sea, the highest lead concentrations in sediments were obtained in those from Inebolu, followed by those from around Zonguldak. The concentrations increased from the middle to the west of the southern Black Sea coast, possibly due to the effect of the Danube River. Sediments taken in September had the highest lead concentrations, followed by samples taken in December.Very high lead concentrations (> 10 Ìg g -1 ) were observed in mussels from those stations where the sediments also contained high concentrations. Mussels had their highest lead concentrations in January and April.

“…Popular approaches tend to normalise data either relative to the abundance of a specific particle size interval class or to carry out their analyses on a specifically separated particle size fraction (e.g. b16 Am (Klamer et al, 1990), b20 Am (Ackermann, 1980;Ackermann et al, 1983;Christiansen et al, 2002), b63 Am Araujo et al, 1988;Klamer et al, 1990), b100 Am (Langston, 1986), b150 Am (Jones and Turki, 1997), b250 Am (Hornung et al, 1989)). Although these methods can be considered reliable and advantageous, they require additional and, in the latter case, time-consuming laboratory work.…”

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.

“…It is necessary, therefore, to first remove this influence by either normalizing data relative to the abundance of a specific particle size interval or fractionating samples into specific sizes (e.g. <16 µm (Klamer et al 1990), <20 µm (Ackermann et al 1983), <50 µm (Aston and Stanner 1982), <60 µm (Ackermann 1980), <63 µm (Araujo et al 1988;), <75 µm (Clifton and Hamilton 1982), <100 µm (Langston 1986), <150 µm (Jones and Turki 1997), <250 µm (Hornung et al 1989). Although these methods can be considered reliable and advantageous, they require additional and, in the case of fractionating samples into specific size ranges, time-consuming laboratory work.…”

Abstract. The use of mineral magnetic concentration parameters (χ LF , χ ARM and SIRM) as a potential particle size proxy for soil samples collected from the Isle of Man (British Isles) is explored as an alternative means of normalizing particle size effects. Comparison of soil-related analytical data by correlation analyses between each magnetic parameter and individual particle size classes (i.e. sand, silt and clay), more discrete intervals within classes (e.g. fine sand or medium silt) and cumulative size fractions (e.g. clay + fine silt) are reported. Both χ LF and χ ARM parameters reveal significant (p <0.05; n = 46), but relatively weak (r s = 0.297 and 0.369), associations with clay content, while χ LF , χ ARM and SIRM parameters have no significant relationship with sand and silt content or any discrete or cumulative size fractions. Contrary to earlier research findings, this indicates that magnetic measurements are not always a suitable particle size proxy and it is only certain environments and/or specific settings that are appropriate for granulometric normalization by this technique. However, if future researchers working in other soil settings can identify a formal predictable relationship, the technique is known to offer a simple, reliable, rapid, sensitive, inexpensive and non-destructive approach that could be a valuable particle size proxy for normalizing particle size effects in soil contamination studies.
