Actually the ink used for most printing these days is a vegetable oil base with other non toxic additives.
The older inks pre-90's did have heavy metals in them to get the correct tint. Now days the inks don't use heavy metals unless it is of a special pantone color, such as a business logo that isn't in the pantone spectra. Even then metallic inks are outlawed in almost every State with the exception of a few. Like VA. W.Va, North and S. Carolina
Even the metallic inks today don't use heavy metals any longer. The paper it's self has more grit than the ink does. Newspaper is a web based printing method and uses almost the same ink as most Industrial printers use.
Hope you enjoyed your printing lesson for the day
