“…The technique allows rapid and accurate measurement of particle sizes within the 0.1-2000 Am range (Syvitski, 1991). All macroscopic organic matter and shell fragments were removed from representative sub-samples before being dampened by the dropwise addition of a standard chemical solution (40 g of sodium hexametaphosphate ((NaPO 3 ) 6 ) per litre of distilled water (Zhao et al, 1999) to help disperse aggregate particles. To ensure complete disaggregation, each sediment slurry was then subjected to ultrasonic dispersion in a Malvern MSX17 sample presentation unit.…”

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 China, heavy metal contamination of riverine sediments did not attract much attention from researchers or governments prior to the year 2000, and relatively few studies were carried out before this time (He et al, 1998;Zhao et al, 1999). Industrial and mining activities that always discharge heavy metals through atmospheric emissions or effluent into the rivers have been increasing continuously and rapidly, especially in the Haihe Basin (Tang et al, 2013).…”

A B S T R A C TA comprehensive and detailed investigation of cadmium (Cd) pollution in surface riverine sediments of the Haihe Basin in north China was carried out. Total Cd concentrations in these sediments ranged from 0.153 to 22.1 mg/kg, exceeding the soil background value at all sampling sites. The mean Cd concentration of the bioavailable fraction was 0.557 mg/kg, accounting on average for 51.58% of the total Cd. A mean value of the Cd enrichment factor of 11.6 suggested that Cd has accumulated in most riverine sediments, resulting in a high degree of anthropogenic pollution. In fact, there were high levels of Cd pollution in the riverine sediments throughout the Haihe Basin, yielding geo-accumulation index values for Cd from 0.071 to 7.25. According to the potential ecological risk index, risk assessment code, and consensus-based sediment quality guidelines, Cd was a serious pollutant in this ecosystem. Because it occurred as a high proportion in the exchangeable/acid soluble fraction (21.21% on average), it may also have biological toxicity. Our findings indicated that it is important to consider Cd in control strategies for managing riverine sediment pollution in the Haihe Basin.

“…Content of transition metals in the fl ood wave have resulted from the water fl ow through farming soils containing cadmium and lead and through the area of the peatland reservation, which contains large amounts of iron and manganese (Siudy et al 2005, Szalińska et al 2010, Ibragimov et al 2010. In other reservoirs (Szczecin Lagoon, Dobczyce Reservoir) and rivers (Severn, Po), increased amounts of transition metals were also noted in the bottom sediments after passing of the fl ood wave, pointing to the infl ow of polluted water from areas surrounding the studied rivers and reservoirs , Fenske et al 2001, Fooken et al 2003, Zhaoa et al 1999 Ibragimov et al 2010). The interaction of heavy metals with humic acids and the effect of particle size on the ability of their accumulation during the passage of the fl ood wave need further study.…”

Abstract:The paper presents the results of studies on the infl uence of the 2010 Vistula fl ood on the humifi cation process in the bottom sediments of the Goczałkowice Reservoir in southern Poland. Due to its location in the vicinity of farmlands, forests and urbanized areas, the Goczałkowice Reservoir is characterized by amplifi ed and intense humifi cation processes within its sediments. The studies were focused on the determining the infl uence of the fl ood wave containing organic and inorganic suspensions on these processes. Humic acids were analyzed using two spectroscopic methods: Electron Paramagnetic Resonance (EPR) and Fourier Transform Infrared Spectroscopy (FT-IR). Application of these methods allowed to determine the values of free radicals and of the g-factor, which are indicators of oxidation, aromatization and maturation of humic acids during the humifi cation process, as well as the value of the 1650/1720 ratio, refl ecting the dissociation of the COOH group to COO -and the formation of complexes of transitional metals with humic acids during the humifi cation process.
