| 英文摘要 | This study was performed to explore acute toxicity of biologically synthesized gold nanoparticles (AuNPs) to a model organismDaphnia magna. Hence, using aqueous extract of marine macroalgaSaccharina japonica, two AuNPs including SJ-AuNPs-72 (72.6 +/- 43.8 nm) and SJ-AuNPs-10 (10.8 +/- 2.8 nm) were synthesized. These AuNPs were characterized by different techniques such as UV-Vis spectrophotometry, transmission electron microscopy (TEM),scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and energy-dispersive X-ray spectroscopy (EDX). The 48-h LC(50)values of SJ-AuNPs-72 and SJ-AuNPs-10 toD. magnawere 1.57 +/- 0.07 and 2.69 +/- 0.12 mg/L, respectively, showing greater toxicity of SJ-AuNPs-72. After exposure of daphnids to treatments, AuNPs were accumulated in gut tract, and lipid droplets under theDaphniacarapace were also observed. Whereas studies on toxicity of biosynthesized AuNPs are still scarce, the achievements of this work are helpful for understanding the toxicity of biosynthesized AuNPs to crustaceanD. magna. |
