I have TFA sour and was about to mix this one up until I read the notes section in this-
http://e-liquid-recipes.com/flavor/913
quote from 'docta' - " Flavor Enhancer; pH reducer; acidifier; "sour" taste ; = MALIC ACID; DO NOT EXCEED 0.5% - 1% This is the sour note in old fashioned sour balls candy as well as salt and vinegar crisps.DO NOT USE WITH NICKEL COILS -->CLASS A CARCINOGENS"
I am using nichrome coils so I have retired this flavour/additive until further notice. Can someone please elaborate and further explain this to me?

***nickel carbonate Nickel carbonates are hydrolyzed upon contact with aqueous acids to give solutions containing the ion [Ni(H2O)6]2+, liberating water and carbon dioxide in the process. Calcining (heating to drive off CO2 and water) of these carbonates gives nickel oxide
NiCO3 → NiO + CO2 The nature of the resulting oxide depends on the nature of the precursor. The oxide obtained from the basic carbonate is often most useful for catalysis.
Basic nickel carbonate can be made by treating solutions of nickel sulfate with sodium carbonate, shown here for the basic carbonate:
4 Ni2+ + CO32− + 6 OH− + 4 H2O → Ni4CO3(OH)6(H2O)4 The hydrated carbonate has been prepared by electrolytic oxidation of nickel in the presence of carbon dioxide:[4]
Ni + O + CO2 + 6 H2O → NiCO3(H2O)4
production of nickel carbonate comprising the following steps: a) Preparing a magnesium salt solution; b) Contacting said solution with a stream of gaseous CO2, keeping pH between 4 and 10 and temperature between 0 and 100°C, during up to 5 hours; c) Contacting the mixture of step b) with a nickel sulphate solution, producing a mixture; d) Performing a separation of liquid and solid portions of said mixture; e) Feeding step a) with said liquid portion. This process recycles the reagent used for producing nickel carbonate and yields a final product that is easy to handle and transport.
You chose a piss poor title for searching purposes, but I can appreciate the discussion here.
Can you elaborate how this title is bad? Seems to be exactly on topic for the question he's asking.
