The determination of emission streams from livestock buildings with different tracer gases.

Author(s) : MULLER H. J., MULLER S.

Summary

The emission of odours and harmful substances from livestock buildings can lead to environmental burdens. The emission of ammonia is regarded as a major problem. Among many factors, ventilation has decisive influence on these emissions. The flow of emissions is especially influenced by the interior air stream pattern, the air velocity near the sources of harmful substances and the arrangement of the air inlets and outlets. In order to better evaluate the influence of such factors, more knowledge about the flow of emissions is required. To determine the flow volume, the authors used the tracer-gas-method. Different tracer gases are compared. The odour concentration is measured with an olfactometer, and the gas concentration is measured with a gas monitor.
