|D = IR*P*RF*ET*EF*ED / (BW*AT) where
*D = dose (mg/kg.day)
*IR = inhalation rate (m<sup>3</sup>/h)
*P = particle concentration in air (mg/m<sup>3</sup>)
*RF = respirable fraction of particles (dimensioless)
*ET = exposure time (hours/day)
*EF = exposure frequency (days/year)
*ED = exposure duration (years)
*BW = body weight (kg)
*AT = averaging time (days) <ref> Schwela D, Morawska L, Kotzias D (Eds.) 2002. Guidelines for concentration and exposure-response measurement of fine and ultra fine particulate matter for use in epidemiological studies. WHO and JRC Expert Task Force meeting, Ispra, Italy, November 2002. </ref>

For dose over a lifetime the formula can be simplified to D = (IR)(P)(RF)/BW [[Category Talk:Class:Dose assessment for fine particles#Boundary | <big>'''B&#8857;'''</big>]]
