Microbial Aerosols: Estimated Contribution of Combine Harvesting to an Airshed

Bruce Lighthart 1
PMCID: PMC239689  PMID: 16346481

Abstract

From plate counts of the airborne microorganisms in the downwind dust plume of operating grass-seed combines, the mean source concentrations were calculated to be 6.4 × 108 and 4.7 × 108/m3, respectively, potentially accounting for at least 41.9% of the bacteria and 35.1% of the fungi in the airshed in the Willamette Valley, Oregon.
