Indoor Air Quality Monitoring includes:

1. Physical parameters consisting of relative humidity, air movement and room temperature.
2. Chemical parameters consisting of formaldehyde, carbon dioxide, carbon monoxide, Nitrogen Dioxide, Ozone, Radon, Respirable Suspended Particulates (PM10) and Total Volatile Organic Compounds (TVOC),
3. Parameters of Microorganisms consisting of Total Bacteria and Fungi.

Indoor air quality (IAQ) in the workplace is the subject of much attention these days, and for a good reason. The indoor environment's air quality can profoundly affect the health, comfort, and productivity of building occupants. Although serious health problems related to IAQ are rare, the perception of endangered health is increasingly common among building occupants.

The causes and consequences of poor IAQ are complex and not completely understood. Still, there are some basic factors that building owners, managers, employers, and occupants should know to address IAQ concerns.

Contaminants may originate from a variety of sources both inside and outside of a building, and may include airborne chemicals, bacteria, fungi, pollen and dust. Although they are not indoor pollutants, factors such as temperature, humidity, lighting, noise and personal and work-related stress can affect occupants’ perceptions of indoor air quality.

Potential sources of contaminants in office buildings include dust; inadequate design or maintenance of heating, ventilation and air-conditioning (HVAC) systems; cleaning chemicals, which may contain irritant vapor and/or volatile organic compounds, or VOCs; pesticides; building materials; office equipment such as copy machines and printers; furnishings; occupant metabolic wastes (respiration and perspiration); fragrances/cosmetics; and tobacco smoke. Of course, virtually all of these are present to some degree in every building. They cause IAQ problems only when concentrations become excessive, usually as a result of being generated at a greater rate than they can be removed by the building’s ventilation system.

Occupants may also unknowingly bring potential contaminant sources into the building on their clothing and their bodies, including dust, consumer products (cleaners, air fresheners, personal hygiene products, etc.) and allergenic particles from their homes, such as cat or dog dander. What occupants do may also affect IAQ, such as blocking air ventilation grills, overusing office chemical products and improperly storing food, which may lead to odors and vermin infestation.

Dusty surfaces, stagnant water, and damp materials provide a favorable environment for microbial growth. When odorous compounds resulting from microbial growth and other microbial particles become airborne, some building occupants may experience foul odors and symptoms including allergic reactions. One potential, but rare infection is caused by Legionella bacteria. Exposure to the Legionella bacteria can cause building-related illnesses (Legionnaire’s disease and Pontiac fever) that can be diagnosed through medical tests.
