“…It is obvious that this picture differs a lot from the results, which were obtained for the raw field sediments shown in Fig. 3 (Schmitt et al 2010a). While the reproduction of the snails increased in most of the polluted sites, the opposite is the case for the extractions.…”

“…In other words, the reference sites were not pristine, but cleaner than the polluted ones. This assumption was confirmed by chemical analysis whereby metals, organotin compounds, natural steroid estrogens, alkylphenols, and PAHs were measured in all native sediments (Schmitt et al 2010a). It turned out that the concentrations of pollutants were in almost all cases significantly higher at the hot spots than at the reference sites.…”

“…The sampling sites (Table 1) spread over industrial areas of three river basins, namely the Elbe, Scheldt, and Llobregat were the same as previously described in Schmitt et al (2010a), where also a detailed overview of the sampling locations is given. For each river basin, two rivers were selected, each with two sampling sites, whereby those two sites were predefined in "reference sites" and "hotspots".…”

“…The experiments were divided in two parts. Within the first part, the raw extracts of all field samples were tested, whereas in the second part, only a few samples that have shown the most significant effects in a previous study (Schmitt et al 2010a) were selected for the whole fractionation study.…”

“…As sampling sites, we selected both reference and polluted sites from three different European river basins. Those sites were selected within the framework of the European project MODELKEY (Brack et al 2005a) and are subject of various studies (Weiss et al 2009;Schmitt et al 2010a;Sormunen et al 2010). This study focuses on the applicability of the sediment contact test with P. antipodarum for effect-directed analysis and should identify problems and possibilities for further implementation.…”

Copper oxide (CuO) nanoparticles (NPs) are among the most widely used engineered NPs and are thus likely to end up in the environment, predominantly in sediments. Copper oxide NPs have been found to be toxic to a variety of (mainly pelagic) organisms, but to differing degrees. In the present study, the influence of CuO NP shape on bioavailability and toxicity in the sediment-dwelling freshwater gastropod Potamopyrgus antipodarum was examined. In 2 separate studies, snails were exposed to either clean sediment or sediment spiked with either aqueous Cu or CuO NPs of different shapes (rods, spheres, or platelets) at 240 µg Cu/g dry weight of sediment (nominal). In neither of the studies was survival found to be related to Cu form (i.e., free ion vs particle) or shape, whereas snail growth was severely influenced by both form and shape. Reproduction was affected (by CuO NP spheres and aqueous Cu) only when estimated as the total number (live plus dead) of juveniles produced per snail per week. Both the aqueous and particulate forms of Cu were available for uptake by snails when mixed into sediment. However, Cu body burden was not directly related to observed effects. The present study stresses the need for both a better understanding of uptake mechanisms and internal distribution pathways of NPs and an assessment of long-term consequences of NP exposure.
