Carbon Nano-tubes pose occupational health hazard

Today whole world is experiencing rapid technological innovation which has changed the face of human living. One such progress is in nanotechnology. Nanotechnology is the manufacturing and application of material and devices at nano scale (1-100 nm) by using unique characteristics of nanoparticles that are different than those of fine and coarse particles. A carbon nanotube is a tube shaped material, made of carbon, having a diameter measuring on the nanometre scale. Carbon nanotubes are formed from essentially the graphite sheet and the graphite layer appears somewhat like a rolled up continuous unbroken hexagonal mesh and carbon molecules at the apexes of the hexagons. 


Carbon nanotubes are major invention to facilitate plentiful industrial operations. These are minuscule, cylindrical, artificial types of carbon and these tubes differ from each other in shape such as some have single-walled while other tube may be multi-walled. Nano tubes also vary in chemical composition such as pure carbon or contain metals or different materials.


Despite of huge investment in nanotechnology, there are key issues of environment and health safety aspect of this technology. Under some conditions, nanotubes can cross membrane barriers, which suggests that if raw materials reach the human organ, they can induce dangerous effects such as inflammatory and fibrotic reactions. Occupational health is a major concern of counsellors and scholars for people who handle dangerous material in environment. Though national government and management take utmost care and adopt preventive measures to improve occupational protection and health of personnel in organization but it is sometimes ineffectual to control the health. With uproar of modern technologies, nanotechnology have varied utilization in diverse area of human consumption. It is well accepted that Nanotechnology has competency to boost productivity of companies because these tiny particles has wonderful application in business.





Today scholars are continually involve in finding health risk associated with nanotechnology. High risk exposure of these nano particles are swallowing through polluted air intake and dermal contact. It was perceived that general exposure to these materials is by inhaling the gas or vaporizer, making skin get in touch with the substance, consumption the material, and even substance is absorbed through eye contact. Personnel in workplace get exposure to nanoparticles in open systems of production where nanoparticles are frequently applied, work with nanoparticles in liquids and in maintenance process such as clean-up extraction systems. The usage of nanostructured powders may lead to airborne nano particulate experience. Specific Carbon nanotubes can increase the chance of lung ailments.



To condense the strands, Carbon nanotubes (CNTs) are some of the most vital materials to result from nanotechnology. Application of nano particles in organizations pose high risks at work environment. Nanotechnology is evolving technology that is mostly applying in various industrial, medical and other sectors to generate revenues and augment the growth of organization. Several researches argue that nano particles have severe ramifications on huge number of workers who are exposed to this during engineering and management of merchandises.

Stem Cell therapy for Neurological Disorders: Life saver or threat

Image
It is claimed in medical reports that stem cells is used in patients suffering from neurological disorders. But it is a stormily debate among researchers and medical experts. Some view this therapy as a lifesaving capsule where as others feared about the consequences of inducing this treatment. Today, people are excited to know that medical specialists have options to treat irreversible ailment of the brain such as onset neurodegenerative disorders like Parkinson’s disease, younger onset inflammatory diseases such as multiple sclerosis or even conditions in which there is an inborn fault of metabolism. Stem cells are part of the body’s normal repair system which substitutes dented or dying cells where possible. In Stem cell therapy, medical experts introduce cells into the damaged tissue in order to treat the disorder or the injury. Stem cells have not yet developed to perform a particular function and are described as unspecialised. Each stem cell has capacity to develop into ...
