Ecotoxicity of silica nanoparticles in aquatic organisms: An updated review

Nanosilicon alters oxidative stress and defence reactions in plants: a meta-analysis, mechanism and perspective

“…65 The large number of NMs used will not only accumulate in the environment, but also enter the skin, digestive tract and vital organs through the food chain. 66 Therefore, in order to promote sustainable development of Si NMs, it is needed to evaluate the toxicity and environmental risks of Si NMs and their related products comprehensively and accurately.…”

Individual and Binary Mixture Toxicity of Five Nanoparticles in Marine Microalga Heterosigma akashiwo

“…In this case, the particles by themselves were dissociated with time in all the combinations (Figure 4b), but the interaction with microalga cells facilitated significant agglomeration of the SMB3 NPs (Figure 5b). The hydrophilic surface of silicon NPs provides their affinity to microalga cells, allows them to easily move in the water body, and increases the possibility of NPs to have a contact with microalga cells [56,57]. Moreover, it was previously demonstrated that the phytotoxicity of silicon NPs increases with an increase in particle size [58].…”

Nanomaterials and Safety Concerns to End Users

“…Although this information should be available for final users, the determination and quantification of NM content in commercial products lead to many technical problems for companies, as they require special techniques and regulations to characterize them [50]. All this is especially problematic since the adverse physicochemical effects that NM can have on living beings remain ambiguous [51]. Not only the final users but also exposed workers and the general public could experience side effects against NM.…”
