Nano-contaminants in the environment and applications of nanomaterials in environmental remediation

Nanoparticulate materials are new but not newly discovered. Nanomaterials chemical composition may be equivalent material in bulk form like particle size in micrometer to millimeter in range. Due to high surface to-volume ratio and small size nanoparticles exhibited new characteristics. Such as TiO2 has been used in high opacity paints as a white pigment for a long time. By contrast, TiO2 particles at nanoscale are transparent to visible light. Increasing reactivity and decreased size of particles are properties that may render more toxic substance. So, the properties that make the technology of nanoparticles interesting place them in potentially toxic substances category. Various number of studies exist regarding the nanoparticles toxicity. These studies suggest that smaller particles are more toxic than larger particles. A big difference exists between these particles according to size. From bulk material to nanoparticles it is not easy to describe the toxicity data. These particles may be inhaled, ingested or taken up through the skin. Different studies have shown that a variety of mammalian cells are capable to take these nanosized particles. But, a little is known about toxicity data to environment and humans. Different variables like weight of molecule, structure, composition, solubility in water, activity, melting or boiling point and structure of particles effect toxicity of these particles and their behavior to the environment.

Methods of environmental remediation are classified as reactive or adsorptive and ex situ or in situ. The nanomaterials use in these scenarios has been investigated. In situ application in groundwater remediation is more appropriate as compare to others. For in situ application, in situ reactive zone must be created with nonmobile nanoparticles or reactive nanoparticle plume that migrates to contaminated zones. For the topsoil application, conventional agricultural practices can be used by which nanoparticles can be worked into the contaminated soil surface. Groundwater and soil contamination methods are closely related; in these methods targeting soil contamination indirectly effect groundwater quality. Groundwater and soil contamination with carcinogenic substances and metals occur over all in the world. Pesticides compound frequently contaminate the groundwater surface. Main source of these pollutants is chemical, agriculture and landfill leakage. Remediation of groundwater and soil is usually very expensive and conventional methods are not always successful or they required long time to become effective. To purify groundwater photocatalyst could be used in pump-and-treat operation, while in situ soil remediation by adsorption and redox reaction.
