What does C stand for in the calculations?

• A. Volume of air per liter
• B. Concentration of fibers per cc
• C. Fiber density
• D. Count of fibers per field

Answer: (B)

C stands for concentration of fibers per cubic centimeter of air. In air sampling, you relate the total number of fibers counted to the volume of air drawn through the sampler, so the result is expressed as fibers per unit air volume (typically fibers per cubic centimeter). This normalization to air volume is what lets you compare results and assess exposure, rather than reporting a raw count, a volume measure, or a count per microscope field.
