A target glitter study.
A target study was conducted using four different pre-selected types of commercial glitter particles. Recipient areas in the general environment around San Diego, California were tested. Glitter particles were recovered using double-sided tape affixed to square plastic Petri dishes. White light microscopy was the only search/identification method used. Additionally, a test was performed of the transferability of cosmetic glitter. Glitter particles were found to readily transfer. Of a total of 48 tape lifts from the general environment, 23 were found to contain at least one glitter particle. But due to the wide variety of glitter particles in terms of colour, shape, size, and surface morphology, the likelihood of transfer of one or more specific target particles was small.
