INDOOR AIR QUALITY

Measurement and Evaluation

Based upon the findings of our initial site visit, it is often necessary to measure and evaluate levels of the environmental factors that are suspected of contributing to poor indoor air quality.  All testing protocols are based on current industrial hygiene practices (NIOSH, USEPA, CDC, AIHA) (SEE RESOURCES PAGE FOR SPECIFIC LINKS) and equipment is factory and field calibrated for accuracy and legal defensibility.  Common examples include:

Chemical Factors:

  • carbon dioxide
  • carbon monoxide
  • oxides of nitrogen and sulfur
  • aldehydes (formaldehyde, gluteraldehyde, etc.)
  • volatile and semi-volatile organics (including petroleum products, pesticides and PCB’s)
  • metals (lead, chromium, mercury, etc.)
  • fibers (asbestos, fiberglass, etc.)
  • toxic dusts (silica, soot, etc.)

Biological Factors:

  • mold (fungi)
  • bacteria (Legionella, Actinomycetes, E. coli or total Coliforms)
  • protozoa
  • viruses
  • arthropods (dust mites, insect parts)
  • mammals (pet dander)
  • allergens

Physical Factors:

  • temperature
  • relative Humidity
  • lighting
  • radiation (ionizing and non ionizing)
  • noise
  • noise (occupational and community)
