| Abstract |
This study quantified the levels of airborne dust and endotoxins present in pig confinement buildings. The dust was separated into 3 size fractions, ≤3.5, ≤8.5 and <51.2µm by means of cyclone pre-separators and a modified cassette holder for total dust. There is a large day-to-day variation in total dust determined in a single confinement building and the smallest fraction (≤3.5µm) varies from building to building but not in a single building. The levels of endotoxin were similar to those found in other studies but indicated that there is a significant enrichment of endotoxin in the size fraction 3.5-8.5µm. The implications from this are that the assessment of the potential health risk to the farmer from endotoxin present in the airborne dust must be assessed by using a biologically relevant criterion based on particle penetration into the thoracic region of the exposed farmer's lung. The current methods of looking at endotoxin levels in respirable and total dust give little information in regard to the potential health risk. |
