The present study reports the successful synthesis of biosynthesized zinc oxide nanoparticles (ZnONPs). The Pandanus Amaryllifolius leaves extract was used as reducing agent with zinc nitrate hexahydrate as precursor. The effects of synthesis temperature on biosynthesis of ZnONP’s are discussed. The biosynthesized ZnONPs were characterized by X-ray diffraction (XRD) ; and they were found to exhibit the hexagonal wurtzite structure. The diffractograms revealed well-defined, strong and sharp peaks at 2θ positions that correspond to its crystallinity with average size of 16.25 nm. Micrograph imag

These nanoparticles may gain access into rivers and marine environments through industrial or household wastewater discharge and thereby affect the ecosystem. In this study, we investigated the effects of silver nanoparticles (AgNPs) and zinc oxide nanoparticles (ZnONPs) on zebrafish embryos in aquatic environments. We aimed to characterize the AgNP and ZnONP aggregates in natural waters, such as lakes, reservoirs, and riv
