October was National Indoor Air Quality Month, an observance aimed at drawing attention to the quality of the air we breathe at home and at work.

Studies conducted by the U.S. Environmental Protection Agency comparing the risks of environmental threats to public health list indoor air pollution from sources such as secondhand smoke, radon, organic compounds, and biological pollutants among the top five risks on a consistent basis.

In general, most indoor air quality problems in the workplace can be pinpointed to six main sources:
• Inadequate Ventilation – These problems involve lack of adequate fresh air and uneven distribution of fresh air within a structure.
• Humidity and Temperature – These concerns involve levels outside the normal range of human comfort.
• Inside Contamination – Possible sources of contamination include office equipment such as copy machines, office and cleaning supplies, and chemicals that are stored indoors.
• Outside Contamination – As the name suggests, this includes contaminants brought into a work environment, such through improper air intake or even changes in wind conditions (for example, vehicle exhaust fumes from a parking garage or loading dock drawn into a ventilation system).
• Microbial Contamination – This is typically associated with water leaks, water infiltration, increased humidity indoors, humidifiers, and contaminated ventilation ductwork – places that can harbor and encourage the growth of microbes.
• New Building Materials – The results from building materials that have just been installed (such as the familiar gas emissions from new carpeting). Such problems can be dissipated by increasing ventilation and typically resolve over time.
