“…In the latter case, however, the study was conducted without bottom sediments. Fabrega et al (2012) also observed its negative influence on the growth and reproduction of the amphipod Corophium volutator. The activity of dissolved ions from NPs is reported as one of the main reasons responsible for the toxic effects of NPs (Adams et al 2006;Beer et al 2012;Yang et al 2012).…”

“…Only a few studies have shown the toxicity of various NPs present in bottom sediments in relation to sedimentdwelling organisms (Oberholster et al 2011;Coleman et al 2013;Hanna et al 2013). These studies have dealt with nanoZnO (Buffet et al 2012;Fabrega et al 2012;Hanna et al 2013), with a lack of data on the toxicity of nano-Ni. Our research revealed significant mortality of H. incongruens in the sediments containing both nano-ZnO and nano-Ni.…”

“…The existing research on NPs in bottom sediments has been conducted using various test organisms. Both the toxicity and accumulation of various NPs have been determined (Oberholster et al 2011;Fabrega et al 2012;Buffet et al 2012;Hanna et al 2013). The impacts of NPs vary substantially, which is dependent on the type of NPs and their concentration, and also on the test organism.…”

“…Evaluation of the influence of aging on the toxicity of NPs is especially justified in benthic sediments due to a much longer retention time of NPs in these sediments compared to other environments (Liu and Cohen 2014). The existing studies have been conducted on sediments recently contaminated by NPs (e.g., Fabrega et al 2012;Hanna et al 2013), which may not reflect the actual conditions experienced in many natural environments. The studies on soils have revealed that NP-induced toxic effects may significantly decrease with the prolongation of contact time between NPs and the soil (Jośko and Oleszczuk 2013).…”

Purpose The intensive development of nanotechnology raises a question of the potential consequences of the presence of nanoparticles (NPs) in the different components of the environment, including sediments. The aim of this study was to evaluate the toxicity of nanoparticles of ZnO and Ni and their bulk counterparts in bottom sediments (SD1, SD2) with different properties collected from the Vistula River in Poland. Materials and methods Sediment samples with NPs at a concentration of 100 mg kg −1 were incubated for 17 months in the dark or under a photoperiod of 12 h light/12 h dark. The Microtox ® (bacteria, Vibrio fischeri) and OSTRACODTOXKIT F ™ (ostracods, Heterocypris incongruens) tests were used to evaluate toxicity. In addition, the contents of Zn and Ni were determined in extracts (H 2 O and CaCl 2 ) of the bottom sediments. Results and discussion The Zn concentration was much lower in the SD1 sediment with the addition of NPs/bulk particles (30-230 μg kg −1 ) compared to the SD2 sediment (280-1140 μg kg −1 ). The toxicity of ZnO and Ni was determined by the type of bottom sediment and the parameter studied.Both nano-and bulk-ZnO and Ni caused the mortality of H. incongruens at a level of 13.3-53.3 %. The influence of ZnO and Ni on the growth of H. incongruens was observed to be the opposite. ZnO resulted in growth stimulation, while Ni resulted in growth inhibition of H. incongruens. Both ZnO and Ni stimulated V. fisheri luminescence. In most cases, the incubation of ZnO and Ni under the photoperiod increased the toxicity or decreased the stimulation of V. fisheri bioluminescence and H. ingongruens growth compared to the darkincubated sediments. Conclusions The study provides new and important information on the ecotoxicological effects of ZnO and Ni nanoparticles in different sediments and under various environmental conditions that may be useful for the risk assessment of this new group of contaminants.

“…Due to their relatively high sensitivity to contaminants and their ecological importance, amphipods are frequently used to test sediment toxicity (Schlekat et al, 1992;Lenihan and Oliver, 1995;DeWitt et al, 2001). Nevertheless, few tests of nanomaterial toxicity with amphipods are published, and of these only two were conducted in sediments (Fabrega et al, 2011;Mwangi et al, 2011).…”

Accumulation and toxicity of metal oxide nanoparticles in a soft-sediment estuarine amphipod

et al. 2013

a b s t r a c tEstuarine and marine sediments are a probable end point for many engineered nanoparticles (ENPs) due to enhanced aggregation and sedimentation in marine waters, as well as uptake and deposition by suspension-feeding organisms on the seafloor. Benthic infaunal organisms living in sediments encounter relatively high concentrations of pollutants and may also suffer toxic effects of ENPs. We tested whether three heavily used metal oxide ENPs, zinc oxide (ZnO), copper oxide (CuO), and nickel oxide (NiO) were toxic to an estuarine amphipod, Leptocheirus plumulosus. We used results from 10-day laboratory bioassays to estimate potential demographic impacts of ENP exposure. We also evaluated fate and transport pathways of the ENPs in the experiments to elucidate routes of uptake and exposure. Dissolved Zn was found in sediment pore water and overlying water samples at 10 fold the concentrations of Cu or Ni, a pattern indicative of the relatively high dissolution rate of ZnO ENPs compared with CuO and NiO ENPs. Accumulation of metals in amphipod tissues increased with exposure concentrations for all three ENPs, suggesting possible exposure pathways to higher taxa. Amphipods accumulated ≤600 g Zn and Cu g −1 and 1000 g Ni g −1 . Amphipod mortality increased with ZnO and CuO concentrations, but showed no significant increase with NiO to concentrations as high as 2000 g g −1 . The median lethal concentration in sediment (LC 50 ) of ZnO was 763 g g −1 and 868 g g −1 for CuO ENPs. Our results indicate that ZnO and CuO ENPs, but not NiO ENPs, are toxic to L. plumulosus and that ZnO toxicity primarily results from Zn ion exposure while CuO toxicity is due to nanoparticle exposure.
