The 143Nd/144Nd of the suspended sediment is slightly more radiogenic on average than that of the bed load, resulting in slightly older Nd depleted-mantle model ages for the bed load compared to suspended load (1.9 Ga vs 1.7 Ga). There is no variation in Sm-Nd isotopic characteristics as...

To bring these results into a broader prospective and understand the overall Pb inputs to the PAD, based on dissolved Pb reported previously (Shotyk et al.45), and Pb in the suspended solids presented here, we find that almost the entire Pb load to the PAD is in the particulate fraction...
organic matter partitioning, suspended solids, dissolved oxygen, silica, and alkalinity. Although many restoration programs try to reduce discharge of phosphorus into receiving freshwaters, strongly bound phosphorus in benthic sediments can remain in the lake for long periods of time. Thus, many programs...
The ADVs were suspended from a buoy at 2, 6 and 8 m depth. The ADV-rig had a total of three positions during the study, Pos. 1 was in the centre of the cage, while Pos. 2 was to the N-E end of the cage, and Pos. 3 was to the S-W of the cage. Both Pos. 2 and 3...
A method allowing to obtain estimates of dissolved organic and suspended matter content in Black Sea waters using beam attenuation coefficient (BAC) measurements in two spectral channels is proposed. It makes possible to assess the composition, bio-productivity and ecological state of waters in real ...
This study provides a comprehensive review of the efforts utilized in the measurement of water quality parameters (WQPs) with a focus on total dissolved solids (TDS) and total suspended solids (TSS). The current method used in the measurement of TDS and TSS includes conventional field and gravi...

In contrast to the dissolved inorganic load (Ca, Mg, Si, Cl, SO4, HCO3) which is adequately assessed by the RHS, for nutrients (N, P, C, Fe, Mn), a rigorous procedure of sampling, filtration, storage, and analysis is largely absent. This limits the availability of information on ...
Peak overloading should not impact the CW’s performance, but ongoing overloading might reduce the treatment capacity due to excess fats, sludge, or SS. For SSFCWs, routine inspections of the pretreatment procedure, pump usage, influent loads, and their distribution over the filter bed are ...
