Diatoms

A major group of algae, they are a common type of phytoplankton. Most are unicellular. They have a silica cell wall and are bilaterally symmetrical, but have many different forms. They are small enough that they can be inhaled and thus tend to be found in the nasal cavity and sinus area. Individuals working with diatomaceous earth would seem to be the most likely to show this material.
