What Airborne Contaminants are Pig Barn Workers Exposed to - Really?

摘要

Pig barn workers are exposed to dust, gases, and endotoxins (Wenger, 1999). Pig barn dust originates from many sources including pig dandruff, dried fecal material and from feed. The gases workers are exposed to include NH_3 (from drying manure and urine on solid floor surfaces), H_2S (a by-product of anaerobic breakdown of manure) and CO_2 gas (a by-product of pig and worker respiration). Endotoxins are constituents of the cell walls of gram negative bacteria.
