Although silver nanoparticles are widely used in a variety of commercial products, there has only recently been a major effort to study their effects on human health. There have been several studies that describe the in vitro toxicity of silver nanoparticles to a variety of different organs, including the lung, liver, skin, brain, and ...
[52] [77] [81] Silver is not an essential mineral in humans; there is no dietary requirement for silver, and hence, no such thing as a silver "deficiency". [52] There is no evidence that colloidal silver treats or prevents any medical condition, and it can cause serious and potentially irreversible side effects, such as argyria. [52]
A majority of silver nanoparticles in consumer products go down the drain and are eventually released into sewer systems and reach wastewater treatment plants. [5] Primary screening and grit removal in wastewater treatment does not completely filter out silver nanoparticles, and coagulation treatment may lead to further condensation into wastewater sludge. [2]
Friends of the Earth has also claimed that silver nanoparticles have a toxic effect on different kinds of living cells. [7] [8] Samsung countered that only an accumulated amount of 0.05 grams of silver is released per machine, per year, while the released silver-ions quickly bind to non-nano-sized structures in the water.
The health impacts of nanotechnology are the possible effects that the use of nanotechnological materials and devices will have on human health. As nanotechnology is an emerging field, there is great debate regarding to what extent nanotechnology will benefit or pose risks for human health.
Wellness influencers say yes, but their claims are slippery at best. Experts explain what seed oils are, their benefits, and why they get so much hate.
A recent study looking at the effects of ZnO nanoparticles on human immune cells has found varying levels of susceptibility to cytotoxicity. [145] There are concerns that pharmaceutical companies, seeking regulatory approval for nano-reformulations of existing medicines, are relying on safety data produced during clinical studies of the earlier ...
Inorganic arsenic is more toxic to humans than the naturally occurring form of the mineral arsenic, and the health effects from exposure are more severe, according to the U.S. Food and Drug ...
