A viral is spreading in facebook and trending in twitter that states :
' .....!! !!!!!! Medical research unit of US has found a new cancer in human beings caused by 'silver nitro-oxide'.....so whenever we buy mobile recharge cards,they should not be scratched by our finger nails....coz they contain 'silver nitro-oxide coating ......which can cause skin cancer.... ....copy n paste the status and spread awareness..May God help us!!'
First thing we should learn is that there is no such compound called Nitro Oxide , But there
is other oxides of Nitrogen such as Nitrous oxide, Nitric Oxide,
Nitrogen Di Oxide etc;
Nitric Oxide is also known as Laughing Gas , which produce
nuerotoxicity through the development of Olney’s lesions which is damage to the posterior
cingulate and retrospenial cortices of the brain .

Recharge cards are made of Latex coating inks which are less harmful which is
used in textile coloring as well .
Scratch coupons are made of a mixture of UV inks as 2 steps
1 ) A substrate covered by a thick layer of UV ink coating
2 ) The above substrate is printed with a scratch off
black UV ink which is further
Used for printing names with another UV color ink.
UV inks are essentially a mixture of colored monomers
and oligomers (the individual
chemical units that eventually form 'polymers' ) and reaction 'photo-initiators' that become
and oligomers form a viscous liquid,
thus serving simultaneously as the 'pigment' and 'solvent' of a conventional ink; they do not
need an organic solvent as a fluid base, and do not 'dry' in air like typical solvent-based inks.
On exposure to UV light, the initiators set off the polymerization reaction, rapidly cross-linking.
The monomers and oligomers into a solid 'plastic' polymer, in a process known as 'curing'.
This polymerization process also inspired the alternative naming of UV inks as 'latex inks'.
There is no involvement of Nitrogen/ Nitric compounds in these reactions and not
hence related with Skin Cancer.
The above hoax messages are created and shared for publicity .
There is no such medical reports or evidence to prove that and those are internet
junks that should not be reposted.
