Rumours on Recharge Cards and Skin Cancer

A viral is spreading in facebook and trending in twitter that states :


 'Cancer-ATTENTION..............​ .....!! !!!!!! 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 

 active when exposed to UV radiation. The monomers 

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.
