Air monitoring is a recognized method to evaluate and characterize air contaminants that may impact the health of the university community, as well as determine the presence of mold and other air contaminants in the workplace. The purpose of these guidelines is to provide a safer working environment for students, staff and faculty. The primary objective is to manage issues with air contaminants

Additionally, this research identified the possible factors which could contribute to breathing zone concentration variations.UTK Environmental Health & Safety Procedure IH-004 This research revealed that the chest sampler provides a consistent relationship to the concentrations measured at the nose for a given job category. Styrene air concentrations detected at the nose were significantly different than those concentrations detected at the other three locations and represented 90 percent, 84 percent, and 76 percent of the left lapel, right lapel, and chest samplers, respectively. Two job classes were studied: the spray gun operators and the rolling and tucking operators. An extensive field investigation in a boat manufacturing plant was conducted where styrene air concentrations were measured by mounting four 3M one-stage diffusion samplers around the worker's breathing zone. It has been generally assumed that vapor is uniformly mixed in the breathing zone therefore, samplers are placed on either lapel or on the chest of the worker. This zone is considered to have an airborne chemical concentration equivalent to the concentration breathed by the worker. Breathing zone samples are used to estimate worker exposure to airborne contaminants by collecting air from a vaguely defined zone surrounding the head.
