The EPA [like the FDA] doesn't have the money to do studies that meet
the standards they demand, is charged with knowing everything but can't and
protecting the most useless of life forms even if they are a human
hazard and they want "industry" to foot the bill [ "or else" ]
In the 60s/70s the Canadian version of the EPA did a study on industrial
silver waste discharge into streams and found it to be reasonably harmless
to fish and fowl, quickly disbursed and isolated as a virtually inert soil
component. It affected certain mollusks near the discharge pipe, somewhat.
However, "Nano Silver" with a direct line to a waste treatment plant or
septic system could sterilize it...but nobody knows if or how much.
And "Nano Metals" are a very new technology that don't behave like
"normal" metals.
Doesn't seem like it would be hard to find out, but getting "acceptable
proof" often goes beyond reason into absolutes...and no business wants to
foot the bill to take the risk of proving itself out of business [or
competitors INTO busness] no matter how small that risk is.
So, in the land of bureaucratic absolutes and very pointy
CYA fingers...nothing happens but a war of words and limits based on
ignorance.

Nanosilver Migrates from Treated Fabric During Washing

Silver nanoparticles used as antimicrobials in fabric can leach out of
clothes as they are being washed. One brand lost over half of its silver
content from the fabric with just two washings.
A group of scientists tested how well silver nanoparticles stayed in
treated fabrics under conditions similar to a washing machine. They
considered mechanical stress and chemical factors such as bleaches, pH and
surfactants.
First, they measured the silver content of several different brands and
types of fabrics that used silver nanoparticles.
They then washed the fabrics in detergent, later adding steel balls to
simulate mechanical stress that would be similar to normal washing
conditions. Some of the fabrics were also treated with bleaching agents
during washing.
When the fabrics were washed in water with detergent only, the silver
generally stayed in the fabrics. However, several fabrics released silver
quite readily once the steel balls were added to mimic mechanical actions
of the washing machine.
Of the seven nanoparticle fabrics subjected to mechanical stress, four
lost roughly 20 percent to 35 percent of their silver with the first wash.
