The term is sometimes expanded to also include nanotechnology's health and environmental impact, but this article will only consider the social and political impact of nanotechnology. As nanotechnology is an emerging field and most of its applications are still speculative, there is much debate about what positive and negative effects that ...
The environmental impact of nanotechnology is the possible effects that the use of nanotechnological materials and devices will have on the environment. [20] As nanotechnology is an emerging field, there is debate regarding to what extent industrial and commercial use of nanomaterials will affect organisms and ecosystems.
Worldwide investment in nanotechnology increased from $432 million in 1997 to about $4.1 billion in 2005. [3]: 1–3 Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, is not yet fully understood.
Nano Technology: On April 2, 2008, the Silicon Valley Toxics Coalition released a report on the nanotechnology's negative impact on community and environmental health. Digital TV Switchover: June 12, 2009, is the deadline for the television industry to switch from broadcasting in analog format to digital. It is anticipated that this change will ...
Effects vary widely over aquatic and terrestrial environments as well as types of organisms. [13] The characteristics of the nanoparticle itself plays a wide variety of roles including size, charge, composition, surface chemistry, etc. [ 14 ] Nanoparticles released into the environment can potentially interact with pre-existing contaminants ...
Ethics of nanotechnology is the study of the ethical issues emerging from advances in nanotechnology and its impacts.. According to Andrew Chen, ethical concerns about nanotechnologies should include the possibility of their military applications, the dangers posed by self-replicant nanomachines, and their use for surveillance monitoring and tracking.

Nanotoxicology is the study of the toxicity of nanomaterials. [1] Because of quantum size effects and large surface area to volume ratio, nanomaterials have unique properties compared with their larger counterparts that affect their toxicity.
These effects cascade into the problems that have now reached an observable scale. [23] As global temperatures rise and oceanic pH drops, some species, such as oysters, will be even more susceptible to the negative impacts of nanoparticles as they are stressed. [23]
