New guidelines make health, safety and energy goals easier to achieve. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the area. In some cases, factors such as how old the source is and whether it is properly maintained are significant. However, less is known about the specific impacts of indoor PM on health. Indoor Air Quality (IAQ) Share. Our leadership team’s deep understanding of the importance of indoor air quality is key to our operations." Poor air quality, both indoors and outdoors, can lead to numerous adverse health problems, such as nausea, headaches, skin irritation, sick building syndrome, kidney failure, and even cancer. Air quality standards are legal standards or requirements governing concentrations of air pollutants in breathed air, ... Another set of standards, for indoor air in employment settings, is administered by the U.S. Occupational Safety and Health Administration. Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. These effects, which include some respiratory diseases, heart disease and cancer, can be severely debilitating or fatal. Other sources, related to activities like smoking, cleaning,redecorating or doing hobblies release pollutants intermittently.

Finally, there are a number of mechanical ventilation devices, from outdoor-vented fans that intermittently remove air from a single room, such as bathrooms and kitchen, to air handling systems that use fans and duct work to continuously remove indoor air and distribute filtered and conditioned outdoor air to strategic points throughout the house. Unless buildings are built with special mechanical means of ventilation, those designed and constructed to minimize the amount of outdoor air that can "leak" in and out may have higher indoor pollutant levels. These include the National Environment Protection (Ambient Air Quality) Measure and World Health Organization guidelines.

In a process known as infiltration, outdoor air flows into buildings through openings, joints, and cracks in walls, floors, and ceilings, and around windows and doors. Exposure to inhalable particles can affect both your lungs and your heart. National air-quality standards for PM were first established in 1971 and were not significantly revised until 1987 when EPA changed the indicator to focus on "inhalable particles", which are particles equal to or smaller than 10 microns (PM 10)..

In response, the European Union has developed an extensive body of legislation which establishes health based standards and objectives for a number of pollutants present in the air. View the on-demand webinars to learn about best ventilation and cleaning practices in schools. While pollutants commonly found in indoor air can cause many harmful effects, there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems. When there is little infiltration, natural ventilation, or mechanical ventilation, the air exchange rate is low and pollutant levels can increase. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. The review ultimately sets out proposed UK indoor air quality guidelines for selected VOCs. Further research is needed to better understand which health effects occur after exposure to the average pollutant concentrations found in homes and which occurs from the higher concentrations that occur for short periods of time. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough fresh outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home.
