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.

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]
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.
In 2014, nanosilver (AgNP) particles were added to Lake 222 in order to determine the impacts of increasing nanosilver pollution on freshwater ecosystems. [59] Over the course of a two-year study period, phytoplankton communities in boreal lakes were found to be unaffected by environmentally relevant nanosilver additions. [ 60 ]
Researchers have developed an inexpensive blood test that they say can detect pancreatic cancer — even in its early stages.. Using a small blood sample, researchers from Oregon Health & Science ...
DJ Unk, the Atlanta MC known for his early 2000s hits including “Walk It Out” and “2 Step," died after suffering a cardiac arrest this week, according to his wife.
Marco Rossi scored with 1:25 remaining in overtime as the Minnesota Wild rallied for a 4-3 victory over the Detroit Red Wings on Saturday. Rossi had just come out of the penalty box after being ...
