ABSTRACT

Anthropological activities release heavy metals like arsenic, zinc, mercury, lead etc. into the environment and produce pollution disturbing the ecosystem. Chemical synthesis of nanoparticles which is used to curb these effects also emits some toxic substances during the synthesis compared to biologically synthesized nanoparticles. Biologically synthesized nanoparticles also have enormous potential and are used against human and plant pathogens, cancer, inflammation etc. Chemically synthesized nanoparticles (NPs) also contribute to heavy metal accumulation (HMA) while bio-synthesized selenium nanoparticles are known to alleviate the heavy metal accumulation. It is notable that the usage of bio-synthesized NPs in agriculture without knowing the accumulation percentage may lead to HMA. In the present study, the SeNPs are bio-synthesized using the Sansevieria cylindrica plant as a capping and reducing agent. The synthesized nanoparticles are tested on earthworms and termites to eliminate the nanoecotoxicology. The colour change of NP solution ranges from pale yellow to brick red, with an absorption range of SCSeNP as 290~300nm in UV-vis spectroscopy. SCSeNPs showed 6 intense peaks in FT-IR analysis and functional groups such as alcohols, phenols, alkynes, 1°amines, aromatics, aliphatic amines and alkyl halides were identified. 7 intense peaks in XRD such as 20.1°, 23°, 23.92°, 24.24°, 27.96°, 27.96° & 29°, presence of Se in EDAX and size of SCSeNP ranges between 117.2 – 192.2 µm obtained through characterization conform to the synthesis. In HMA study through AAS method, 2.0ppm of accumulation range has been obtained. The mortality rate of earthworms was observed in vitro. This proves that this bio-synthesized SCSeNP can be capable to be used in nano drugs and agriproducts like fertilizer, pesticide and so on.
