PCB Inhalation Accumulation Model

Estimate inhaled PCB mass during a repeating work schedule.

Exposure inputs

PCB air concentration

µg/m³

Inhalation Rate

m³/day

Years Exposed

years

Workdays per Year

days/year

Hours per Day

hours/day

Accumulated PCB mass 8.00 mg

Full-day inhaled PCBs: 19.20 µg/day
Daily dose (scheduled hours): 6.40 µg/workday
Total workdays: 1,250 days
Time factor (work hours ÷ 24): 0.3333
Total exposure hours: 10,000 hours
Accumulated mass: 8,000 µg

Accumulation of PCBs Over Time

Screening estimate assumes constant air concentration and inhalation rate during scheduled work hours, with 100% of inhaled PCB mass counted as accumulated mass. It does not model absorption, metabolism, or elimination.
