“…On the other hand, our data regarding the dose dependent toxicity of AgNPs, are in agreement with those of Siller et al [15] in which the animals showed significant defects and, at the highest concentration of AgNPs, they were unable to reach the blastula stage. In the same paper of Siller et al [15] the release of Ag + ions was so limited that the effects could not be ascribed to the ions.…”

“…However, the AgNPs toxic effects cannot be ascribed to the twinning defects shown by the AgNPs, in agreement to other works [15,23] or correlated with the release of Ag + ions since their release was prevented by the glucose capping [24]. The stability of AgNPs, capped with glucose is very efficient and thus their use for testing the toxicity of the AgNPs on aquatic animals is more suitable than other methods of NPs preparation, like for example citrate-stabilized AgNPs.…”

“…In the same paper of Siller et al [15] the release of Ag + ions was so limited that the effects could not be ascribed to the ions. The effects of the bulk are negligible in relation to the effects exerted by the NPs and are measurable at longer time, much more long that the duration of our experiment (72 h) [27].…”

“…Indeed, since embryos are particularly sensitive to low level environmental pollution, they represent widely used animal models to test environmental pollutants of various chemical nature [15]. Among the animals, the sea urchin P. lividus is the suitable model for assessments of seawater quality [16], ecology [17], development biology [18], embryology, and biomineralization processes [19].…”

Silver and carbon nanoparticles toxicity in sea urchin Paracentrotus lividus embryos

Environment hazards and risks of engineered NanoParticles (NPs) have been debated in recent years. In this paper, the effects of silver (Ag) and carbon (C) NPs were explored in sea urchin Paracentrotus lividus (P. lividus) development. Fertilization and development of P. lividus up to the pluteus stage were assayed in the presence of increasing amounts of NPs. The embryotoxicity test performed on sea urchin P. lividus, from fertilization until the larva stage, revealed that both AgNPs and CNPs were embryotoxic since they caused embryo malformations and alteration of the normal progression through the development stages. Embryonic development was slowed down by AgNPs and sped up by CNPs. Interestingly, AgNPs-induced malformations led embryos to die in a concentration-dependent manner; while embryos bearing CNPs-induced malformations survived for a longer time.

“…On the one hand, some studies support the theory that the toxic effect of AgNPs, whether coated or not, is derived from the release of Ag+ (Fabrega et al, 2011;Yang et al, 2012;Buffet et al, 2013), which causes cell damage via an increase in ROS production and an induction of apoptotic pathways (Hwang et al, 2008). On the other hand, some have concluded that the AgNP effect is related to the particle itself (Siller et al, 2013;Choi & Hu, 2008;Griffitt et al, 2012). Nevertheless, it is established that the toxicity of AgNPs is influenced by how well the particles are dispersed within the medium (Kim, Truong, Wehmas, & Tanguay, 2013).…”

Using immune cells of sea urchin Strongylocentrotus droebachiensis in early development as a model, the cellular protective mechanisms against ionic and poly(allylamine)-coated silver nanoparticle (AgNPs; 14 ± 6 nm) treatments at 100 μg L were investigated. Oxidative stress, heat shock protein expression, and pigment production by spherulocytes were determined as well as AgNP translocation pathways and their multiple effects on circulating coelomocytes. Sea urchins showed an increasing resilience to Ag over time because ionic Ag is accumulated in a steady way, although nanoAg levels dropped between 48 h and 96 h. A clotting reaction emerged on tissues injured by dissolved Ag (present as chloro-complexes in seawater) between 12 h and 48 h. Silver contamination and nutritional state influenced the production of reactive oxygen species. After passing through coelomic sinuses and gut, AgNPs were found in coelomocytes. Inside blood vessels, apoptosis-like processes appeared in coelomocytes highly contaminated by poly(allylamine)-coated AgNPs. Increasing levels of Ag accumulated by urchins once exposed to AgNPs pointed to a Trojan-horse mechanism operating over 12-d exposure. However, under short-term treatments, physical interactions of poly(allylamine)-coated AgNPs with cell structures might be, at some point, predominant and responsible for the highest levels of stress-related proteins detected. The present study is the first report detailing nano-translocation in a marine organism and multiple mechanisms by which sea urchin cells can deal with toxic AgNPs.
