"Nanoparticles in air, for instance, have moved to the center of attention because of their well documented effect on public health (Peters et al., 2000). They are deposited in the alveoles of the lung, where the defense mechanisms of the human body are weak; in this way, a number of toxic chemicals adsorbed at the nanoparticle surface penetrate into the human body using the nanoparticles as vehicles. Another example is the precipitation forming process in clouds. It depends to a large extent on the presence of nanoparticles acting as condensation nuclei for ice and water. This has a significant influence on the albedo of the earth and on rain and snowfall (Rosenfeld, 2000). "
