TL;DR: In this paper, the authors measured ammonia and carbon dioxide (the latter for estimating ventilation rates) at seven locations inside and one location outside in four replicates of each housing type over 24h under summer and winter conditions.

TL;DR: In this article, a field survey of dust concentrations within and dust emissions from cattle, pig and poultry buildings was conducted in England, the Netherlands, Denmark and Germany, where measurements of inhalable and respirable dust concentrations were made in 329 buildings and CO 2 within and outside the buildings were also measured to estimate ventilation rates for dust emission calculations.

TL;DR: The concentration of airborne endotoxins and microorganisms in livestock buildings (cattle, pig, poultry) was surveyed in four European countries (England, The Netherlands, Denmark and Germany) as mentioned in this paper.

TL;DR: In this paper, three methods for the calculation of the ventilation rate in Northern European livestock buildings were compared on the basis of the balances of animal heat, moisture and carbon dioxide for fattening pigs, dairy cattle and laying hens.

TL;DR: In this paper, a large survey of the emissions of aerial pollutants within and from livestock buildings in Northern Europe was conducted, covering pigs, cattle and poultry and the major housing types.
