I have seen barium in sheetfed inks. Has anyone seen any of the other
RCRA Toxicity Characteristic metals in sheetfed inks (arsenic, cadmium,
chromium, lead, mercury, selenium, or silver?)
I understand that most if not all colors are available with inks that do
not contain toxic metals for pigmentation. However, I would like to
know which metals printers should watch out for when assessing whether
their waste inks meet RCRA's Hazardous definition.
Any experience with putting metal containing inks through the TCLP
test? Do the metals leach?
