Researchers study biological transfer in food chain

TEHRAN, Aug. 06 (MNA) – Iranian researchers investigated the possibility of biological transference of nanoparticles in a simplified marine food chain whose results can be used in increasing safety in food chain and environment.

Nanoparticles finally enter aqueous media, soil and air but their effect on these media is still unknown. Therefore, it is expected that the emission of particles into ecosystems severely affects the living creatures, including plants. According to Iran Nanotechnology Initiative Council (INIC), the aim of this research was to study the possibility of biological transfer of silver nanoparticles in a simplified marine food chain from one type of fish to another.

This research studies the possibility of biological transfer of silver nanoparticles from Artemia to zebrafish. Biological accumulation of silver nanoparticles was firstly measured at food level in an individual manner. To this end, the level of silver nanoparticles was firstly measured in Artemia body. Then, nanoparticles were fed to Artemia, and Artemia was fed to zebrafish. Finally, the accumulation of nanoparticles was measured in zebrafish body.

This study was an initial investigation on the determination of possibility of biological transfer in a food chain. Achievements of this research are important for the beginning of other findings, but further investigations are required to prove the results. Final confirmation of the results may lead to the presentation of new results in the possibility of biological transfer of various nanoparticles to decrease some concerns in the health and hygiene of food.

Results of the research have been published in Aquaculture, Aquarium, Conservation & Legislation – International Journal of the Bioflus Society, vol. 9, issue 1, 2016, pp. 100-104.
