“…This is also supported by earlier studies which have revealed TiO 2 ENPs to be generally non-toxic to D. magna in dark conditions [50,51]. However, it was observed that at higher concentrations TiO 2 ENPs formed a layer on the carapaces of the daphnids, affecting their inability to move freely.…”

The present study investigated changes in suspension stability and ecotoxicity of engineered nanoparticles (ENPs) by addition of Suwannee River natural organic matter and aging of stock and test suspensions prior to testing. Acute toxicity tests of silver (Ag), zinc oxide (ZnO), and titanium dioxide (TiO2) ENPs with Daphnia magna were carried out following Organisation for Economic Co‐operation and Development test guidelines. Daphnia magna was found to be very sensitive to Ag ENPs (48‐h 50% effective concentration 33 μg L−1), and aging of the test suspensions in M7 medium (up to 48 h) did not decrease toxicity significantly. Conversely, the presence of Suwannee River natural organic matter (NOM; 20 mg L−1) completely alleviated Ag ENP toxicity in all testing scenarios and did not aid in stabilizing suspensions. In contrast, addition of Suwannee River NOM stabilized ZnO ENP suspensions and did not decrease toxicity. Aging for 48 h generated monotonous concentration–response curves in the presence and absence of Suwannee River NOM. At concentrations up to 100 mg L−1 TiO2 ENPs did not cause immobilization of D. magna under any of the tested conditions. Presence of Suwannee River NOM caused agglomeration in stock suspensions. The authors' results suggest that aging and presence of Suwannee River NOM are important parameters in standard toxicity testing of ENPs, which in some cases may aid in gaining better control over the exposure conditions but in other cases might contribute to agglomeration or elimination of ENP toxicity. Therefore, modifications to the current guidelines for testing ENPs should be evaluated on a case‐by‐case basis. Environ Toxicol Chem 2015;34:497–506. © 2014 SETAC

“…The bioluminescence of V. fisheri was stimulated under the influence of both NPs (ZnO and Ni) and their bulk counterparts. The existing studies using V. fischeri have shown the toxic effect of various NPs (including ZnO) Strigul et al 2009). It should however be stressed that these studies have been conducted only for aqueous solutions Mortimer et al 2008).…”

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.
