Sampling methods and measurement strategies for dust and ammonia concentrations in production animal buildings

Research output: Contribution to journalArticlepeer-review


Air contaminants (i.e., dust, microbes and gases) inside production animal buildings can harm the health and productivity of animals and the health and comfort of workers. The need to monitor and control indoor air quality in animal buildings exists. This study was conducted to review the sampling methods and strategies for measuring dust and ammonia concentrations in production animal buildings. Current technology for dust measurement includes integral dust samplers (total, inhalable and respirable dust samplers), real-time instruments (photometer and optical particle counter) and size-resolving samplers (cascade impactor, optical particle counter). Current technology for ammonia measurement includes tube or card sensors, electronic chemical sensors and light absorption sensors. Commonly used methods for production animal buildings include the filter sampler for total dust concentration, optical particle counter for number, concentration and size distribution and detector tube for ammonia concentration. Research is needed to evaluate other real-time instruments such as the photometer for dust and electrochemical diffusion sensor for ammonia. Additionally, research is needed to establish standard sampling procedures and strategies for production animal buildings.
