No. I believe that it wont affect anyone even so. Recently I attended a class about PCB manufacturing. I read about few chemicals there. So some chemicals like the etching solutions, Acidic Cupric Chloride and Ferric Chloride are not available in local stores here. So these are the chemicals which is available around this place. I just went through some chemistry texts to look for some combination which can make any of them. failed miserably. Someone who is good in chemistry might help, so am here.

What happens when these chemicals are mixed. Ferric Chloride + copper ? Copper sulphate + Calcium hypochlorite ? Copper sulphate + Calcium Carbonate ? Copper sulphate + Sodium Bicarbonate ?
