Flat plate collectors and collectors with sidewalls 10 and 50 mm high were placed on a slow-speed turntable to minimize positional effects. For each sampler type, collection intervals of 1, 3, 6 and 12 wk were used. The collection medium was generally a 47 mm glass fibre filter located on a 75 mm diam. aluminium disc. Cellulose nitrate membrane filters were used for one treatment. The dust sedimentation rate determined from the weekly samples varied from 80 to 200 mg m-2h-1 over the 12 wk period. Dust deposits on the filters varied linearly with time from 2.3 mg\/cm2 of collector surface for the 1-wk interval to 27.9 mg\/cm2 over 12 wk. The measured dust sedimentation rate was about 3.0% less on the membrane filters than on the glass fibre filters and also for those collectors with the 50 mm high sidewall when compared with the flat plate collectors. The length of sample collection interval did not significantly affect the measured dust sedimentation rate. It is suggested that handling errors and edge effects may affect accuracy when deposits are greater than about 7 mg\/cm2 of collector surface.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The relative collection efficiency of several different types of dustfall collector was assessed over different collection intervals in a piggery.
