Protecting Swine Worker Health: Determining the Best Combination of Airborne Contaminant Reduction Technologies to Reduce Odours, Dust and Gases
Description: There are about 7 125 pig buildings in Canada where thousands of workers are exposed to large concentrations of odorous compounds, gases, dust and bioaerosols. These airborne contaminants are also emitted from exhaust fans of buildings which put rural communities at risk. Over the years, different strategies have successfully reduced some airborne contaminants, but no study has yet characterized the combined effect of several technologies on emissions from pig buildings. The main objective of this study is to evaluate the reduction of odorous compounds, dust and gases (ammonia, methane, carbon dioxide and nitrous oxide) from the use of 3 studied airborne contaminant reduction strategies for pig buildings: manure separation, oil sprinkling and biotrickling filter These technologies were used alone and in combination with each other in order to determine the best combination of technologies to be implemented in a commercial-scale pig building. To compare the effect of the different technologies, 8 environmentally controlled chambers housing 4-5 grower/finisher pigs were used to produce the airborne contaminants. Animals are kept on a 100% slatted floor with the manure being stored in a shallow pit located under the floor. The air temperature, humidity and flow rate were monitored continuously over each 7 week trial. Samples for gas measurement were collected at 4 hour intervals while dust and odours were sampled at weekly and biweekly intervals respectively. This paper will present the results for odour, dust and gas emissions obtained from each combination of the 3 technologies tested over 3 replicates.
