Numerous studies in the last decade have linked ink to cancer.  Most recently a Swiss study actually found the ink printed on cereal boxes can be highly toxic.  Few question what seems to be a relatively harmless liquid that is literally intertwined with most aspects of daily life.

Sadly it’s true that ink can contain mineral oils that can pose serious health risks to humans.  Certain oils have very real links to issues like inflammation in internal organs, and even cancer directly.

Perhaps one of the most commonly overlooked inks is the type used in tattoos.  In less scrupulous tattoo parlors investigations have revealed chemicals in the ink, including toxic metals and compounds known to be potent skin carcinogens.  While the FDA has launched investigations into these concerns about ink safety, the more than 45 million Americans sporting tattoos these days seem unphased by the risks.  To be sure we’ll see studies in the near future that tie tattoos to cancer, and given the increase in te popularity of tattoos are likely to see the incidence of cancer rise even further.

Even seemingly harmless, empty ink cartridges pose a real risk to us all.  Each year millions of inkjet and laser printer cartridges find their way into landfills.  In these cases the ink is less of a concern than the actual plastic casing.  Plastics used in ink cartridges actual contain toxic oils which over time can leech into ground water, just one additional way our critical water sources come in contact with potential carcinogens.

While the research is indeed troubling, it’s an important step in highlighting the dangers that lurk all around us.  Thankfully recent studies have grabbed the attention of groups like the FDA who can certainly do something about it.  It’s certainly not a problem that is going to be solved overnight, and the fallout from ink-related cancer will certainly continue for many decades.
