Biochemical and behavioural responses of the endobenthic bivalve Scrobicularia plana to silver nanoparticles in seawater and microalgal food

Toxicity of CeO2nanoparticles on a freshwater experimental trophic chain: A study in environmentally relevant conditions through the use of mesocosms

“…Indeed, no toxicity occurred with the extremely high NP concentration of $100 mg/kg of dry body weight in Pleurodeles, but mortality was observed at the intermediate accumulation value (13.5 mg/kg), in mesocosm experiment. This result is in accordance with previous studies that underline that no direct relationship exists between NP bioaccumulation and toxicity (Buffet et al, 2013a;Jackson et al, 2012).…”

Tissue specific responses to cadmium-based quantum dots in the marine mussel Mytilus galloprovincialis

“…An increase in the activity of this enzyme was also observed in bivalves exposed to others metals and metal-based ENPs (e.g. Ag NPs, CuO NPs, CdS QDs) (Canesi et al, 1999;Buffet et al, 2013Buffet et al, , 2015Gomes et al, 2012), confirming that GST represents an important defense response against metals and metalbased ENPs toxicity. Thereby when the bivalve antioxidant response is not sufficient to prevent the ENP-induced oxidative degradation of lipids (LPO), GST can act as a compensatory mechanism and reduce the toxicity of the compounds derived from LPO.…”

Gammarus fossarum (Crustacea, Amphipoda) as a model organism to study the effects of silver nanoparticles

“…A few studies investigated and clearly demonstrated that AgNPs are taken up in aquatic organisms such as molluscs (Ali, 2014;Buffet et al, 2013;Canesi et al, 2012;Ringwood et al, 2010), crustaceans (Andreï et al, 2016;Georgantzopoulou et al, 2013;Ulm et al, 2015) and fish (Ašmonaite et al, 2016;Griffitt et al, 2013;Jung et al, 2014;Kwok et al, 2012), and behave differently depending on their physico-chemical characteristics. In this way, size, coating and chemical composition were suggested as important contributing factors to the toxicity of AgNPs (Castranova, 2011;Vale et al, 2016).…”
