| Abstract | Silver is a noble metal with antique values and antimicrobial property. Being its colloidal form, silver nanoparticles have wide commercial application. They are being used extensively in the aquaculture industry. Considering their dumping and leaching in water, experiments were conducted to estimate their toxicity on zebrafish (Danio rerio). Silver nanoparticles were synthesized using sodium borohydrate (chemical synthesis) and Guava (Psidium guajava) leaf-extract (biological synthesis) as reductants. UV–Visible spectroscopy exhibited a confirmatory surface plasmonic range of 390–410 nm and transmission electron microscopy data projected a homogenous, round (11–45 nm) and polygonal (17–40 nm) particles of the silver nanoparticles synthesized in chemical and phyto-synthesis routes respectively. Acute toxicity study of these chemicals was conducted in static bioassay method. 96 h LD$_{50}$ dose for silver nitrate was 100 μg l$^{−1}$ where as it was 80 and 400 μg l$^{−1}$ for chemically and biologically synthesized silver nanoparticles respectively. The calculated safe concentration values in water were 0.020, 0.033 and 0.153 mg l$^{−1}$ for silver nitrate, chemically synthesized nanoparticles and biologically synthesized silver nanoparticles respectively. These candidate chemicals had not influenced any significant alterations in water quality. Current investigations confer that chemically synthesized silver nanoparticles are more toxic than silver nitrate to zebrafish. Biologically synthesized silver nanoparticles are least toxic among all. These trends of impact were also evaluated and reconfirmed through histological assessment of ovarian tissue at sublethal dose (1/10 th of LD$_{50}$ value). Thus, the potentiality of plant derived nanoparticles should be investigated in different fish models for their sustainable application in aquaculture and water technology. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
