Commonly Associated Particles

Particles have compositions that are also commonly found in environmental particles from numerous sources. Discussion-When present in addition to particles that are characteristic of, or consistent with, GSR, or both, these particles can be of use in the interpretation of a population of particles and, consequently, the likelihood that that population is GSR. In isolation, however, such particles have little use in examinations for GSR.
