Synthetic silvernanoparticles (AgNPs) are being extensively used in our daily lives; however, they may also pose a risk to public health and environment. Nowadays, biological AgNPs are considered an excellent alternative, since their synthesis occurs by a green technology of low cost and easy scaling. However, studies with these biologicalnanomaterials (NM) are still limited. Thus, a more careful assessment of their industrial application, economic feasibility and ecotoxicological impacts is crucial. The aim of this study was to investigate the effects of different concentrations of mangrove fungusAspergillus tubingensis AgNPs on the aerobic heterotrophs soil microorganisms, riceseeds (Oryza sativa) and zebrafish (Danio rerio). Biogenic AgNPs were less harmful for soilmicrobiota compared to AgNO3. On riceseeds, the AgNPs displayed a dose-dependent inhibitory effect on germination and their subsequent growth and development. The percentage of inhibition of riceseedgermination was 30, 69 and 80% for 0.01, 0.1 and 0.5 mM AgNPs, respectively. After 24h of AgNPs exposition at a limit concentration of 0.2 mM, it did not induce mortality of the zebrafishD. rerio. Overall, A. tubingensis AgNPs can be considered as a suitable alternative to synthetic nanoparticles.
