The NIOSH REL for cellulose (paper dust) is 10 mg/m3 (total dust) and 5 mg/m3 (respirable dust) as a full-shift time-weighted average. The REL is based on eye and skin irritation. ... Because dioxins and furans have very low vapor pressures, most respiratory exposures would probably occur as a result of inhalation of contaminated paper dust. Work areas with the highest concentrations of airborne paper dust (and to a lesser extent, bleached pulp mist or dust) would likely have the greatest potential for inhalation exposure to PCDDs and PCDFs.
