The Potential Human Health and Environmental Implications of Nanotechnology (original) (raw)

Nanotechnology is the engineering of functional systems at the molecular scale. Nanotechnology is the understanding and control of matter at dimensions of roughly up to 100 nanometres. Nanotechnology is the creation of useful materials, devices, and systems through the manipulation of matter on this miniscule scale. The emerging field of nanotechnology involves scientists from many different disciplines, including physicists, chemists, engineers, and biologists. Nanoparticles fall into three major groups: natural, incidental, and engineered naturally occurring nonmaterial's such as volcanic ash, ocean spray, magnetotactic bacteria, mineral composites and others exist in our environment. Incidental nanoparticles, also refered to as waste particles, are produced as a result of some industrial processes. The third category of nanoparticles is engineered nanoparticles-these are the particles associated with nanotechnology. Nanotechnology concerns dealing with environmental and health implications and regulatory compliance encompass practicing areas for these technical individuals. The role of nanotechnology in the field of environment and health is positive but improper handling and regulation of above type of nanoparticles and nanotechnology sometimes cause serious harm to the environment as well as on human health. They cause environmental degradation in respect of change in qualities of environment by mixing of particles and affect the health of human beings like cancer and other harmful diseases. The purpose of this technology is to figure out the science and to protect human health and our environment.
