Identification of livestock husbandry systems with lowest pollutant emissions

Emissions of aerial pollutants within livestock buildings can impair animal and human health and may also harm the rural environment. The major aerial pollutants are organic dusts, gaseous ammonia and micro-organisms, which are responsible for disease spread, noxious odours and rural pollution. Research is underway to reduce pollutant emissions and improve animal and human health by identifying those systems of livestock husbandry with the lowest emissions.

Sampling methods have been investigated for a field survey of aerial pollutants in livestock buildings. Methods have been developed for measuring concentrations of airborne dust, micro-organisms and ammonia, ventilation rate and meteorological variables. Some novel techniques have been devised and initial tests undertaken. A specification has been formulated for a mathematical model of pollutant dynamics.

Evidence for high emission of aerial pollutants has been shown, especially in pig and poultry houses. Minor differences between the countries involved (Netherlands, Denmark, Germany and United Kingdom) were found but more substantial effects were due to the type of building.
