To investigate how particulate materials and the toxicity of a polluted river can affect biomass production of a particle feeding organism, monthly water samples of the River Lambro were collected upstream and downstream from major pollution sources. These samples were characterized for physical and chemical endpoints, and tested for acute and chronic toxicity (7-day) using Ceriodaphnia dubia. Comparing the effects of unfiltered and filtered water samples, we showed that: (a) despite the higher contamination of the downstream reach, unfiltered (whole) downstream samples often supported a higher biomass production of C. dubia than upstream samples; (b) filtering downstream water samples and thereby removing suspended particulate matter (SPM) controlled this compensatory effect and resulted in a clear inhibition of daphnid biomass production; (c) despite the compensatory and likely nutritional role of particulate materials, an inverse relationship was found between daphnid biomass production and the content of organic carbon of SPM, as well as between the SPM organic content and the temperature of the river. These results show that SPM of the downstream reach can simultaneously exert trophic and toxic effects, and their interaction determines the final result but under the control of major system factors such as water temperature.

Marine sediments are part of the hydrological cycle and the ultimate storage compartment of land-derived organic matter, including pollutants. Since relevant microbially-driven processes occurring at benthic level may affect the quality of the overall aquatic system, the necessity for incorporating information about microbial communities functioning for ecosystem modelling is arising. The aim of this field study was to explore the links occurring between sediment contamination patterns by three selected class of organic pollutants (Polycyclic Aromatic Hydrocarbons, PAHs, Nonylphenols, NPs, Bisphenol A, BPA) and major microbial properties (Prokaryotic Biomass, PB; total living biomass, C-ATP; Prokaryotic C Production rate, PCP; Community Respiration rate, CR) across a gradient of anthropogenic pollution. Sediments were sampled from 34 sites selected along 700 km of the western coastline of the Adriatic Sea. Organic contamination was moderate (PAHs <830 ng g-1; NPs <350 ng g-1; BPA <38 ng g-1) and decreased southward. The amount of PAHs-associated carbon (C-PAHs) increased significantly with sediment organic carbon (OC), along with microbial functional rates. The negative relation between PCP/CR ratio and OC indicated the shift toward oxidative processes in response to organic pollution and potential toxicity, estimated as Toxic Equivalents (TEQs). Our outcomes showed that sediment organic contamination and benthic microbial processes can be intimately linked, with potential repercussions on CO2 emission rates and C-cycling within the detritus-based trophic web.

Recent climate changes associated with anthropogenic emissions of pollutants are triggering shifts in global biogeochemical cycles and polar marine ecosystem. The decrease of sea ice and the mechanism of ice formation/melting, may considerably have an impact on the mobility of contaminants and on the loss of biodiversity. In this work, we report the occurrence and bioaccumulation of selected endocrine-disrupting compounds (EDCs) in muscle and liver of the Greenland shark Somniosus microcephalus, an arctic species of interest for biogeography, migration, physiology, long- and short-term contaminant storage. the EDCs selected for this study were 4-nonylphenol (4-NP), its mono- (NP1EO) and di-ethoxylate (NP2EO) precursors and bisphenol A (BPA). There are currently very few scientific papers on the distribution and transport of these EDC s in the arctic marine food web and no such studies have been performed on the Greenland shark. Totally, muscles and liver samples were analyzed from 23 Greenland sharks (TL range 149-442 cm) sampled in W, SW, SE, and NE Greenland. Extraction of analytes from biological matrices were performed by ASE (Accelerated Solvent Extraction), followed by HPLC-Fluorescence (FLD) detection. Results showed higher contamination levels in muscle than in liver in the sharks from SE and NE Greenland, while in specimens from W and SW Greenland the liver was the tissue more contaminated. In fact, the 4-NP, NP1-2EO and BPA mean content in liver of SW Greenland specimens was 43.5 ng/g, 288.5 ng/g and 8.2 ng/g wet wt respectively, while in muscle mean concentrations was 20.3 ng/g for 4-NP, 171.1 ng/g wet wt for NP1-2EO and 7.9 ng/g for BPA. Results confirm the presence of selected EDCs in this species, suggesting the transfer of contamination in the Euro-Arctic marine trophic web.

Valsecchi, S. in OpenAIREUnder climate-change conditions, temporary rivers will be the dominant surface-water bodies of the Mediterranean region. In order to manage this kind of water body appropriately, it is necessary to understand the chemical and ecological processes that involve hazardous substances in these environments. The processes during the dry phase have an important influence on the mobility and the availability of hazardous substances. This critical review presents the state of knowledge on the fate and the monitoring of hazardous substances in temporary rivers and highlights future trends in research in this field

Temporary rivers are characterized by dry-wet phases and represent an important water resource in semi-arid regions worldwide. The fate and effect of contaminants have not been firmly established in temporary rivers such as in other aquatic environments. In this study, we assessed the effects of sediment amendment with Polycyclic Aromatic Hydrocarbons (PAHs) on benthic microbial communities. Experimental microcosms containing natural (Control) and amended sediments (2 and 20 mg PAHs kg(-1) were incubated for 28 days. The PAH concentrations in sediments were monitored weekly together with microbial community structural (biomass and phylogenetic composition by TGGE and CARD-FISH) and functional parameters (ATP concentration, community respiration rate, bacterial carbon production rate, extracellular enzyme activities). The concentration of the PAH isomers did not change significantly with the exception of phenanthrene. No changes were observed in the TGGE profiles, whereas the occurrence of Alpha- and Beta-Proteobacteria was significantly affected by the treatments. In the amended sediments, the rates of carbon production were stimulated together with aminopeptidase enzyme activity. The community respiration rates showed values significantly lower than the Control after 1 day from the amendment then recovering the Control values during the incubation. A negative trend between the respiration rates and ATP concentration was observed only in the amended sediments. This result indicates a potential toxic effect on the oxidative phosphorylation processes. The impoverishment of the energetic resources that follows the PAH impact may act as a domino on the flux of energy from prokaryotes to the upper level of the trophic chain, with the potential to alter the temporary river functioning.
