Silver nanoparticles (AgNPs) are widely used and have various applications, including medicine, electronics, textiles. However, their increasing use raises concern about potential environmental impact, particularly on aquatic organisms, such as fish, which the primary consumers of environments can be exposed to AgNPs through routes. For this purpose, leaves plant species Bellis perennis were a reductive agent convert silver nitrate into AgNPs, assess its toxicity against fish. Well-dispersed undersized obtained confirmed using analytical techniques, Scanning Electron Microscopy (SEM) Transmission (TEM). Moreover, shown significant antibacterial activity Aeromonas hydrophila (25.71 ± 0.63) Vibrio harveyi (22.39 0.29). In addition, was assessed by exposing Cyprinus carpio concentrations, 0.06, 0.1, 0.2 mg/L. The findings revealed that significantly accumulated in intestine, followed gills, liver, muscles, kidney, brain. This bioaccumulation led histological alterations destruction villi regeneration liver cells, degeneration gill lamella. RESEARCH HIGHLIGHTS: Plants based synthesis is mostly considered eco-friendly A mediated found less toxic profoundly causes alterations.
