| Summary: |
Airborne pollutants in, and emissions from livestock
buildings a¤ect animal and human health and welfare
and contribute to environmental air pollution. Field surveys
have shown the inßuence of livestock species and
management strategies on pollutant emissions. However,
to verify these Þeld survey measurements and to ensure
representative results from short-term studies, a comprehensive
experimental study in both a force-ventilated
fattening piggery and a naturally-ventilated broiler house
was also carried out, to achieve measurements with
a high resolution in position and time.
For the force-ventilated piggery, ventilation rate was
measured directly using fan-wheel anemometers and by
the CO2 balance method. Inhalable dust concentration
was measured with a gravimetric procedure, while
a micro-balance using a mass-sensitive oscillator allowed
additional on-line measurements of dust concentration,
e.g. for comparison with measured levels of animal activity.
Concentrations of the gaseous components CO2 and
NH3 were detected mainly using a photo-acoustic multigas
monitor. For NH3 only, absorption tube and wet
chemical analysis were also used. This suite of methods
enabled comprehensive studies of the behaviour of airborne
pollutants in and emissions from livestock buildings.
The results are reported in Part 2 of this paper. |
