Summary of The Proposed Outcome.

The proposed study will be the first in India to analyze ecotoxicological effects of nanoparticles. The releveance of the same can not be overstated given the extremely high levels of pollution caused by effluent discharges into the coastal waters from metropolis and industrial towns in India. The indiscriminate and unregulated adoption of newer technologies with greatest with scant regard for their environmental and social externalities is the greatest threat to sustainable develoment. The study will also be relevant as a pioneering effort in an enviromentally pertinent issue and will pave the way for build up of a knowledge base regarding biological effects of a form of chemical species that have come to dominate the fileds of commericla application in rescent times and show great potential for increase usage in ever increasing applications in the future.


1. The release of newly synthesized nanopartilcle as a product from different industries is responsible for imbalance of aquatic ecosystems and marine population that leads to deterioration of rare aquatic fauna so the current study acts a foundation on conducting clinical trials in aquatic environment in the field of toxicology. 

2. It shows all the results(biochemical, histological) in a lower taxonomic level hence i ensures the risk factor potentially.
3. The project is extensively analysed, assessed, observed, discussed and concluded that it has got some level of: 
(i) Environmental risk- affects the ecosytstem. 
(ii) Health risk- affects the physiological system of living organism. 
(iii) Society risk- Unequal distribution of powers. 
(iv) Economic risk-barrier between developing and developed country. 
(v) Technological risk- uncontrolled revolutionized product 
(vi) Hence the project shows the possible advocacy measurements and regulations which should be necessarily taken during every instant of new nanoparticle release to the aquatic environment.
