ecological concerns (Wiesner and Bottero 2007) and benefits. While talking about
environmental nanotechnology all the four spheres of earth (Fig. 3.2) are need to be
addressed.

Applications of Environmental Nanotechnology
Completely changed properties of nanosystems from their macro-sized counterparts
or parent elements make them materials of interest for different environmental
applications (Louie et al. 2016). Most of the interest is shown by the researchers
for designing of nanomaterials to treat pollution problems. One such example is of
nano-cellulose owing to its mechanical properties accompanied with property of film
formation, has been used for fabrication of separating membranes for air and liquid
