Utilization of nanotechnology and nanomaterials is an integral part of
modern life. The increased use of nanomaterials in various consumer products, industries,
medical instruments, and information technology and energy sectors has created
research interest because of their potential toxicity for the environment. Nanomaterials
can also be added directly and indirectly to the soil and water treatment plants to
reduce pollutant concentrations. Nanoparticlesmay enter the aquatic system through
runoff and industrial effluent discharge, therefore, potentially contaminate both the
aquatic and terrestrial systems. Researchers have used laboratory experiments to
understand the effect of nanomaterials and their transformation in water and soil
environment. The transformation of nanoparticles in the environment involves various
physical and chemical processes, and their degradation/transformation products
may introduce further toxicity. Various microparticles or host materials can be used
to support or coat nanoparticles in order to reduce their toxicity. Microparticles
including clay minerals, polymer, carbon-based materials (biochar) are popular to
support nanoparticles due to their large surface area and improved functional characteristics. This chapter aims to give an overview of the risks associated with using
nanoparticles, and how to reduce the possible toxicity related to nanoparticles by
using microparticle host materials.
