Anaerobic piggery lagoons are the major source of odor from piggeries in Australia. Data from recent research indicates that up to 75% of the odor emitted by an Australian piggery is from the primary lagoons (Smith et al., 1999). Six piggery lagoons in southeast Queensland were sampled from February 2001 to August 2001 using a wind tunnel. Six or more odor samples were taken from each lagoon’s surface using an equidistantly spaced grid pattern. The number of sample points on each lagoon was proportional to the lagoons surface area. Samples were taken using a wind tunnel. Odor concentration determination was undertaken using a dynamic olfactometer and odor emission rates (OER or E) were calculated using standard formula.
