Silver nanoparticles disrupt olfaction in Crucian carp (Carassius carassius) and Eurasian perch (Perca fluviatilis)

Impact of Predator Cues on Responses to Silver Nanoparticles in Daphnia carinata

“…However, previous studies have found a different toxic effect between Ag ions (as AgNO 3 ) and AgNPs (Asharani et al 2008;Roh et al 2009). In addition, some researchers propose that toxicity of AgNPs is a result of both the uptake of intact AgNPs and the release of Ag ions (Liu and Hurt 2010;Bilberg et al 2011;Poynton et al 2012; Janssens and Stoks 2013a). Poynton et al (2012) compared gene-expression patterns in daphnids exposed to AgNPs and Ag ions and concluded that the toxicity of AgNPs in an acute exposure were likely due to both AgNPs and the released Ag ions.…”

Predicting the environmental impact of nanosilver

“…Furthermore, Bilberg et al (2010) showed an increased basal metabolic rate in juvenile Eurasian perch (Perca fluviatilis) in response to a 3-day exposure to 63-300 g/L PVP-coated AgNPs. Bilberg et al (2011) also demonstrated that a 30 min exposure to PVP-coated AgNPs (0.45-45 g/L) disrupted olfaction in the Eurasian perch and the Crucian carp (Carassius carassius), whereas Schultz et al (2012) and Katuli et al (2014) demonstrated the ability of AgNPs to inhibit Na + /K + -ATPase activity in rainbow trout (Oncorhynchus mykiss) and zebrafish (Danio rerio), respectively, affecting plasma ion levels and even increasing levels of the stress hormone cortisol.…”

Perturbation of cellular mechanistic system by silver nanoparticle toxicity: Cytotoxic, genotoxic and epigenetic potentials

“…Eurasian perch [179]. Chronic toxic effects of Ag NPs were found against Drosophila at bactericidal concentration of 5 mg L -1 of Ag NPs which manifested in form of decreased in fecundity of flies, but also found that flies adopt to Ag NPs environment after long term exposure of low concentration, but higher concentration induce acute toxic effect which impair their developmental cycle [180].…”
