In the past few decades, application of nanoparticles has been central in the development of science and new technologies. Nanoparticles are being used in many techniques such as water purification, use in jewelry, pesticide removal and other medical applications. The major advantage of the use of nanoparticles is that they offer minimal reactivity with other materials because of their electrochemical potential, molecular potential etc even when used in bulk. But this usage of nanoparticles has made them exposed to our natural environment and they can be found in our natural environment along with other organic and inorganic environmental contaminants. Therefore it is very important to know the analytical chemistry of these nanoparticles to keep a check on its distribution in our natural environment. Knowing the chemical properties of nanoparticles will lead to the knowledge of the extent up to which nanoparticles can influence the environmental behavior, extent up to which they can contaminate the drinking ground water and extent of their ingestion by human beings. The analytical chemistry will also let us know about the affect of nanoparticles on ecological factors such as, sea creatures, land dwelling animals.
