What are the risks of nanotechnology in the society?
Nanoparticles can get into the body through the skin, lungs and digestive system. This may help create ‘free radicals’ which can cause cell damage and damage to the DNA. There is also concern that once nanoparticles are in the bloodstream they will be able to cross the blood-brain barrier.
What are the possible environmental risks of nanotechnology?
Nanomaterials reaching in the land have the potential to contaminate soil, and migrate into surface and ground waters. Particles in solid wastes, waste water effluents, direct discharges, or accidental spillages can be transported to aquatic systems by wind or rainwater runoff.
How will nanotechnology affect social economic and political relationship?
It is likely that nanotechnology will further widen the gap between the means of political violence available to the military and those available to the civilian population. The advancement of nanotechnology might contribute to terrorism, as it can exacerbate existing trends towards asymmetric warfare.
What are the negative impacts of nanotechnology on the environment and society?
While these are considered to be the positive effect of nanotechnology, there are certain negative impacts of nanotechnology on environment in many ways, such as increased toxicological pollution on the environment due to the uncertain shape, size, and chemical compositions of some of the nanotechnology products (or …
What are the effects of nanotechnology on human and environmental health?
Therefore, by detecting pollutants by specific sensors, we can help protect the sustainability of human health and the environment. Thus, nanotechnology provides us with a new approach to cut down the waste production, reduce the emission of greenhouse gases and discharge of hazardous chemicals in water bodies.
How does nanotechnology affect the economy?
