Other particles come in on the air, either through open doors and windows, or through ventilating systems. Moisture in buildings can support the growth of microorganisms with potential for health problems. Research suggests that easily re-suspended particles will not accumulate on active surfaces. Particles will move deeper into the pile in the case of carpet, they will be removed via ventilation and filtration, or they will move to a more quiescent location. Controlling humidity reduces microorganisms and bacterial growth.
Science provides little evidence of the effectiveness of bake-outs.
In most cases, the temperature differential is not high enough or long enough to have any significant impact on emissions. Evidence suggests that less-traveled areas of public buildings frequently are grater contributors to indoor air quality problems than highly traveled areas, and structures that contribute to piled papers are a repository for potential pollutants. Architects should design with help in mind, avoiding cubicles when possible, keeping work areas open and avoiding tight spaces.
