There are increasing numbers of concerns regarding the use of Nano-silver. The following are some of those concerns:
Depending on how the silver is fixed into the fabric, as much as 80% can wash out in just three washes.
Any silver that is washed out ends up in the environment, either in the water courses, or in slurry which is then spread onto fields.
Silver does not break down. Ever. This means that any silver in the environment can cause damage to that environment, affecting aquatic life, killing bacteria in the soil (which is vital to helping crops grow).
There is a finite supply of silver left! Some estimate that at the rate we are consuming silver, ground reserves could run out in as little as 50-80 years. There is concern over nanoparticles of silver accumulating in our bodies and the effects that it can cause within us. Side effects can range from colouring of the skin and/or eyes, to neurological problems. The research and
documented side effects are still limited but there is an ever-increasing body of work in this area.
It is very difficult – if not impossible – to ‘recharge’ garments at home with silver, so the efficiency of these
garments’ antimicrobial capacity is likely to be very limited after a relatively short space of time.
