INDOOR AIR QUALITY

 

 

Indoor Air Quality, (IAQ), has emerged as a risk to public health due to the pervasiveness of indoor air pollution, (IAP), and human exposure to indoor pollutants. The increase of contaminated air due to chemicals and synthetic materials in our homes and work places coupled with today’s tighter, more insulated buildings have created more potential hazards. Since 1970, information on the health risk associated with indoor air pollutants (IAP), has increased steadily. Because the general population is indoors most of the time and because of the pervasive nature of IAP, no one is immune to its effects.

Those that are affected by IAP may experience symptoms such as irritation of the eyes, throat, and nose. Other reported health risks include headaches, dizziness, fatigue, central nervous system disorders (CND), allergic sensitivity reactions, and a variety of other respiratory and health problems. There are more severe symptoms that are contributed to IAP. Once it is determined if there are air pollutants in your home or workplace, you are able to determine the best course of action to take. ASTEM Environmental. Inc. possesses the required testing methods, insights, experienced environment professionals and equipment that help to minimize and mitigate the adverse effects of IAP.

Indoor air POLLUTION (IAP)

Poor indoor air quality can be traced to many factors. Among some of the causes of contaminated indoor air quality, the National Institute for Occupational Safety and Health, (NIOSH) has noted are: microbial contamination, contamination from inside the building (including fire damage and water damage), contamination from outside the building, inadequate ventilation, and fabric contamination. ASTEM Environmental. Inc. has the expertise to deal with the complete range of causes for contaminated air and poor indoor air quality.


Healthy Indoor Environment

The quality of air contributes to productivity, comfort, and a sense of health and well being in a healthy indoor environment. The indoor air should be free from significant levels of odors, dust and contaminants and circulates to prevent stuffiness without creating drafts. Occupants should be free from feeling sick. Temperature and humidity should also be appropriate to the season and to the clothing and activity of the building occupants.


What Can ASTEM do for you?

Samples of airborne viable fungi are collected using an Andersen 1 ACFM Viable (Microbial) 2 Stage Particle Sizing Sampler with a built-in critical orifice designed to sample 1 cubic foot of air per minute when attached to a vacuum pump capable of sustaining a negative vacuum pressure of 10 inches of mercury or more. The sampling device is designed to separate particles into the respirable range (particles ranging in size from 0.65 to 1.1 microns) and non-respirable (particles ranging in size from 1.1 microns and greater). The upper stage traps respirable particles on an agar plate, which consists of 20 ml Sabbouraud Dextrose agar in a 100-mm diameter Petri dish. The lower stage traps non-respirable particles.
