<abstract displayLabel="Summary">The effect of ventilation on concentrations of ammonia in typical Finnish cowhouses was investigated. Temperature, relative humidity, and concentration of carbon dioxide also were measured. A tracer-gas technique and multipoint equipment measured ventilation. Samples for airborne ammonia were collected in impinger flasks and analyzed by a gas-specific electrode</abstract>
