Temporal variation of indoor air quality in an enclosed swine confinement building.
Human health hazards can exist in swine confinement buildings due to poor indoor air quality (IAQ). During this study, airborne dust and ammonia concentrations were monitored within a working farrowing facility as indicators of IAQ. The purposes of this study were to assess the temporal variability of the airborne dust and ammonia levels over both a daily and seasonal basis, and to determine th...
متن کاملIndoor Air Quality
The issues of indoor air quality are complex and can be directly influenced by a number of system and building parameters. There are no universal solutions for every problem since there are numerous potential contaminant sources. They may originate from indoors and have a direct impact on indoor environmental quality, or they may originate from outdoors and be transferred by a mechanical or nat...
متن کاملIndoor air quality.
Complaints in modern buildings have been attributed to inadequate ventilation for the last 20 years. Few data exist to support this claim. In fact, few studies have actually looked at ventilation and complaints at the same time. These missing studies indicate a failure of three groups of professionals, physicians and health scientists, architects and engineers, and scientists knowledgeable in e...
متن کاملIndoor Air Quality Measurement
A qualitative assessment of indoors air quality is presented, by the use of an electronic nose consisting of a gas sensor array, a data acquisition system and a pattern recognition system. The gas sensors are sensitive to gases polluting the indoors air but they are sensitive to indoors temperature and humidity as well. The data acquisition system overtakes the sensors specific response and out...
متن کاملIndoor Air Quality in Submarines
The next generation of conventional submarines will be submerged for several weeks, creating a need for regenerative air purification methods and new air monitoring instruments. Submarine air is a complex mixture of compounds, where the most obvious contaminant is metabolically produced carbon dioxide. Normal eight-hour occupational exposure limits are not applicable on a submarine, instead spe...
