“…To our knowledge there are no studies in the literature investigating the HI and OI behavior of lacustrine sediments affected by treated and untreated waste water sewage. Only in the Mediterranean Sea a similar HI and OI behavior in sludge deposit sediments has been observed as a product of sewage discharges (Kruge et al 2010). For the first time, the combination of TOC, MinC, C/N, HI and OI results obtained in the present work permitted to characterize the "algal-type" signal obtained in unit III (Fig.…”

Toxic trace metals in lacustrine sediments are of major concern since they can be hazardous to biota and human health. A high-resolution multiproxy study, including trace metals and major elements (measured by ICP-MS and XRF), total organic carbon, mineral carbon, Hydrogen Index, Oxygen Index, and C/N ratios, was performed on a sediment core from Vidy Bay in Lake Geneva. This bay has been affected by hazardous compounds released via the sewage effluent of a major wastewater treatment plant (WWTP). Anthropogenic trace metals, such as Pb, Cd, Cu, Zn, and Hg, increased following the industrial revolution in Europe. The highest amounts of these toxic metals, together with Ni, Cr, Co, Ag, Bi, and Fe, were recorded in sediments from 1964, the date of the WWTP implementation. During this period, all trace elements exceeded the sediment quality guideline “probable effect concentration” (PEC), with the following maximum concentrations (in mg /kg): Pb 4000, Cd 23, Cu 1200, Zn 8600, Hg 11, Ni 140, Cr 270, Ag 130, and Bi 310. The geochemistry of detrital elements (Al, Si, Ca, Ti, K, Zr, Rb, and Sr), as well as S, Fe, P, and the nature and quality of organic matter were clearly also affected by the effluent. The sedimentary record revealed that, after some improvements in the wastewater treatment processes and the relocation of the outlet pipe, the sediments tended to return to concentrations similar to those prevailing before the WWTP implementation. However, despite the reduction in the contamination load from the WWTP, which could be reinforced with the construction of a new plant in the near future, the sediments deposited in Vidy Bay represent a major contaminant legacy that constitutes a potential threat to the lake biota in the case of sediment remobilization

Lumbrinerids are amongst the most abundant and diverse polychaete families in worldwide continental shelves, and have received attention recently through the description of several new species and new occurrences. Herein, a total of four lumbrinerid species are firstly reported in the eastern and southern Spanish continental shelf, extending their biogeographic distribution to the western Mediterranean Sea and increasing up to 25 the number of species known in the Iberian Peninsula coasts. New insights on taxonomy, ecological and biogeographic preferences and an updated taxonomic key for Iberian coasts and surrounding areas are also provided.

“…In practice, pyrolysis GC-MS (Py-GC-MS) may confirm or even improve upon the usual information obtained with the more common GC-MS fingerprinting methods. Pyrolysis GC-MS has been successfully applied in environmental studies related to sediment contamination (de Leeuw et al, 1986;Richnow et al, 1995;Faure and Landais, 2001;Mansuy et al, 2001;Kruge and Permanyer, 2004;Kruge et al, 2010;Micić et al, 2010Micić et al, , 2011Kruge, 2015), http wastewater effluents (Greenwood et al, 2012) and industrial waste (Ishikawa et al, 2005).…”
