Respirable and Inhalable Dust Concentrations within and Emission Rates from Australian Piggery Buildings

摘要：

　　Concentrations and emissions of airborne inhalable and respirable dust within and from 160 piggery buildings were sur-veyed in four states of Australia.Respirable and inhalable dust samples were collected on filter papers using standard gravimetric measure-ment methods.A refereed methodology was used to predict the emission rates from all buildings studied.An overall mean inhalable emis-sion rate of 174.6 mg/h/pig and a mean internal uilding concentration of 1.74 mg/m3 were measured in the piggery buildings.An overall mean emission rate of 40.1 mg/h/pig and a mean internal concentration of 0.26 mg/m3 were measured for respirable dust.The lowest in-halable dust concentrations were measured in dry sow buildings(0.804 mg/m3 ),while measurements taken in weaner buildings had the highest concentrations(2.66 mg/m3 ).Straw based shelters had the highest mean respirable dust concentration(0.64 mg/m3 )and emis-sion rate(1771.7 mg/500 kg live weight).
