Nanotechnology Being Used In Products Despite Toxicity To Humans And Environment

When the nano technology was first introduced in the early 1980s, most of the people were amazed by this spectacular idea. Share holders invested a lot of money in nano based industries because they knew the next growing business is nano technology.
‘Nano’ means extremely small or mathematically it means one billionth (10-9) of a meter, so Nanotechnology is that knowledge and ability that can construct potent devices by engineering a single atoms until they are molecularly sized.
After only three decades the industries working on this technology is so much enhanced that we are fascinated at how technology is advancing and how efficient we can use the resources around us to make life easier. Nanotechnology is being used every day to develop new electronics and cosmetic products. However, are we really being environmentally friendly by producing and using these products?
The more the particles become small, the more it is a threat to human defense system. Today many leading multi-national cosmetic companies are manufacturing these nano-particle contained products that can be toxic to humans and their environment. Some bizarre facts about the harmful effects of nano particles are listed below:-
1.    In 1997, an Oxford scientist discovered that nano-particles found in sunscreen created free radicals that had damaged DNA.

2.    In 2004, British scientist Vyvyan Howard published initial findings that had indicated gold nanoparticles might travel through a mother’s placenta to the fetus.

3.    In early 2002, the University of California in San Diego revealed that cadmium selenide nanoparticles, also known as quantum dots, may cause cadmium poisoning in humans.

4.    In 2002, CBEN (Center for Biological and Environmental Nanotechnology) indicated that nanoparticles accumulated in the bodies of lab animals and fullerene could easily travel through soil and be absorbed by earthworms. This is a potential link up in the food chain to humans.

Nanotechnology may appeal as the wave of the future and advancement in skincare with the allure of warding off signs of aging but consumers must understand the damage these nano particles can do to the human body.
