This report had for objective to provide scientists and advanced advisers with information and basic facts about the following subjects:
– production and dispersion of dust (airborne particles) and gases inside livestock buildings;
– emissions of particles (pathogens excluded), gases and odour from livestock buildings to their surroundings;
– practical and useful measurement methods of measuring the contaminants;
– effect of the contaminants on humans and animals;
– methods to reduce indoor production, concentrations and emissions of contaminants.
This report does not present information about emissions and engineering aspects of storage and manure handling inside or outside the building. And this report doesn’t deal with animal comfort.

General information of the aerial environment in animal housing is well presented with the principal phenomena and the possible solutions available.
