The findings of the study will be reported at the 6th International meeting on the Environmental Effects on Nanoparticles and Nanomaterials to be conducted at the Royal Society in London from 21 to 23 September 2011.
Lead scientist, Richard Handy stated that at this phase of the research, it is not clear whether these impacts are a result of the entry of the nanoparticles into the brain or by a secondary effect of nanoparticle reactivity or chemistry.
Professor Handy stated that it is worrisome that the impact of nanoparticles on the fish brain have some similarities with other materials such as mercury poisoning and it is a matter of concern that these materials may bio-accumulate and cause a gradual or permanent hazard to humans and wildlife.
The findings of the Professor Handy's research and that of other scientists studying the nanoparticles’ biological effects may have an influence on policy regulations for nanomaterials with regards to human safety and environmental protection.
