RE: Re: Metals in Printing Ink

For the record, a friend of mine needed a barium enema when pregnant and
her son was born mildly retarded. No one knows for sure what caused it,
but there were no other known genetic or environmental factors.

What you say is correct, Debby.

We should consider some additional relevant information, however. First,
during my 11 years in the printing industry, never did an environmental
agency raise a red flag about barium, either in the information that I
supplied to them or in any discussions held between EPA and the printing
industry trade associations' environmental committees, several of which
I was actively involved with.

Note also that the organo-metallic compounds that make good pigments are
highly stable as they would need to be to make the inks colorfast.
Colorfastness is the property of printing inks that enables the images
on the products with which they are printed (magazines, inserts, etc.)
to maintain their intended properties. These properties are maintained
for an extended amount of time-through the printing process, through
shipment to the newstand, through the ride home with the purchaser,
through the dash in the rain into the house, through the weeks on the
coffee table in the sunlight, through the years in the local library
and, yes, even through the decades in the landfill.

Colorfastness avoids faces that turn green or images that fade to
invisibility. Barium, copper and iron are the bases of those
organo-metallic pigments-in the same way that magnesium is the basis for
chlorophyll (a green "pigment", albeit not a very colorfast one) and the
way iron is the basis of hemoglobin (the red "pigment" that is the
carrier of oxygen in your red blood cells). Consequently, the barium
that is the basis of barium lithol red (magenta) pigment, and the copper
and iron that are the basis of two blue (iron blue and cyan)
organo-metallic pigments used in printing inks are not readily available
to the environment.

You might also be interested in knowing that the vitamins that I take
every day contains...you guessed it-barium, iron and copper. It even
contains chromium which many consider worse for the environment...and
for humans...than the others. Micro-nutrient experts have been showing
that these and many other minerals are essential to human health and
longevity. The only two metals that are known to be harmful-i.e. zero is
the only appropriate human consumption level-are mercury and lead.

One final comment, Debby. The medical diagnostic community uses barium
to make soft tissue in a subject's digestive system show up on x-rays.
If an individual who is experiencing stomach pain is faced with a barium
cocktail as a means of diagnosing his or her ailment, should he or she
refuse just because barium is a RCRA metal?


      Barium is also a RCRA metal, in addttion to lead and chromium.
      Also, note that a chemical present at 1%, as some metals are in
      these inks, is still concentrated at 10,000 ppm!  Thhe haz waste
      toxicity charcteristic metal concentrations are far less than
      10,000 ppm!  Chemicals that represent less than 1% by weight in a
      product formulation do not have to be listed on an MSDS and maybe
      up to 10,000 ppm in concentration!  Be careful relying on percent
      by weight info and relating to haz waste concentrations...

                  One good way to search for info. on this subject is to
                  use the search feature on the PNEAC web site.  I typed
                  in metal and found the following information:

                  A good contact on this question is:

                  On June 1, 1998 Doreen Monteleone of FTA answered
                  essentially the same question from Donna Pederson of
                  MinnTAP as follows:

                  If the inserts were printed flexographically, it is
                  unlikely. Most ink
                  companies have stopped adding lead, mercury, cadmium
                  or hexavalent chromium
                  to flexo inks. I'm aware that Minnesota regulates the
                  use of these and
                  have recently consulted a few ink companies.

                  Hope this helps.

                        I have a question regarding the color inserts in
                        newspapers (I believe it's a flexographic
                        process). Does anyone know if they still use
                        metal inks in printing these? Does anyone know
                        when they were phased out if they were? I have
                        looked on the print-tech archives, and didnt'
                        see it answered, and posted a question, but it
                        didn't seem to get a response.

                        Anyone have any suggestions?
