Carbon Black is in everyday and specialty products.

Is carbon black listed on California Proposition 65?

“Carbon black (airborne, unbound particles of respirable size)” was added to the California Office of Environmental Health Hazard Assessment (OEHHA) list of substances known to the State to cause cancer on February 21, 2003.  The listing was triggered by the ‘authoritative’ body mechanism in the California Code of Regulations and is based on the IARC reclassification from 1995/96.  All three criteria of the listing must be met for carbon black to be considered a Proposition 65 substance.

What analytical method should be used to determine the concentration of PAHs on carbon black?
