In less than four
decades, nanotechnology has emerged with impacts on rapid technological and
social transformation of our lives. Nanotechnology is defined as the
manipulation of matter at or near-atomic and molecular scales to produce
nano-particles that have unique and novel chemical and physical properties
intended for specific functions. There are many commercial applications of
these emerging nano-particles including electricity, clothing, and electronics.
While this is a good thing, there is a potential for negative biological
activities in humans that are significantly different from those exhibited by
materials of similar chemical composition, of say, fine to bulk-size materials.
Therefore, by characterizing the physical and chemical properties of engineered
nano-particles at various life cycle stages can provide information necessary
for their oversight. This presentation focuses on understanding various forms of engineered nanoparticles v. chemical and physical characteristics and the potential risks posed by these emerging materials; a nanoinformatics framework for collecting and collating information necessary for the oversight of engineered nano-particles; and the state of knowledge to prevent and control of occupational and environmental exposures to engineered nano-particles.
There exists an enormous amount of information on the toxicity of engineered nano-particles. This information can be extrapolated to predict human and environmental health effects; and can clearly support the functions of environmental health specialists.
