Reducing worker exposure to gases, odours, dust and human pathogenic agents in pig farm buildings


Pig farmers are exposed daily to significant quantities of gas, odours, dust and bioaerosols. They are at risk of developing respiratory disorders or infectious diseases. This risk reflects the number of hours spent inside farm buildings and the concentration of different contaminants.

There are a number of technologies to reduce concentrations of gas, odours and dust inside buildings, but there is no data on bioaerosol reduction.

This research will evaluate four technologies, used singly or in combination, to gauge their effectiveness in reducing gas, dust, odours and bioaerosols in pigsties, in order to identify the best one. These technologies include a new floor slat concept, using sawdust to separate liquid and solid phase slurry, oil spraying and filtration of air leaving the building.
