Personal exposure to airborne particulate matter due to residential dryer lint cleaning
Abstract Exposure to airborne particles during and after cleaning dryer lint was examined via 30 experiments involving 4 dryers in a laundry room of a Northern California home. Gravimetric and real-time air samplers measured mass and size-resolved number concentrations in close proximity to the cleaning activity. The size distributions varied greatly between loads of clothing, with particle diameters > 10 μm contributing the bulk of the airborne lint dust volume. Average 5-min exposures to PM10 varied from < 10 to > 300 μg/m3. Cumulative frequency distributions of 1-min-averaged PM10 measurements were used to characterize the probabilities of different short-term exposure levels during and at different elapsed times after lint cleaning.

Highlights Lint cleaning suspends mostly coarse particles - it is difficult to gravimetrically collect sufficient PM2.5 mass. The rapid release of a sizable lint dust cloud near the person performing cleaning resulted in 1-min PM10 exposures>1000 μg/m3. All 1-min exposures dropped below the WHO 24-h ambient PM10 guideline (50 μg/m3) 6 min after cleaning. There were no strong correlations between the mass of bulk lint cleaned and levels of PM10 exposures.
