Indoor Air Quality (IAQ) Method EPA 323 / 8260

CO, CO2, PCB, Formaldehyde, Radon, VOC

The EPA describes common indoor pollutants that might be present in your home or business.

  1. Biological pollutants, like mold, dander, pollen, dust mites, and bacteria

  2. Chemical pollutants, which include volatile organic compounds (VOCs) like formaldehyde, and the other chemical pollutants lead and radon

  3. Combustion pollutants, like carbon monoxide and tobacco smoke (incidentally, VOCs and other chemical pollutants may result from combustion)

Volatile organic compounds (VOCs) are an important class of indoor air pollutants; with indoor concentrations generally higher than outdoors. Formaldehyde is a priority VOC because of its frequent occurrence in indoor air and the serious health outcomes resulting from exposure. Taking formaldehyde as a representative VOC, this chapter reviews the knowledge necessary to develop solutions to indoor VOC pollution. The toxicology of formaldehyde is briefly reviewed. Then the current understanding of VOC emission behavior is discussed, including experimental techniques for measuring emissions, modeling approaches for predicting emissions, and the impacts of environmental factors on emissions. With a comprehensive understanding spanning emission characteristics and toxicology, it is possible to develop effective strategies to maintain indoor VOC concentrations below a safe threshold.

A typical test of this type can detect the presence of several environmental contaminants and toxins in a building—including mold, allergens, lead, asbestos, radon, VOCs and formaldehyde in the air—offering a comprehensive approach to IAQ testing. The tests provide actionable results that can be used to improve the health and well-being of building residents and workers.

We always hear stories about people having headaches, sneezing, dizziness. In almost every case we will find the source. There is not a common contaminants for each project or building we test. Because we are experts in this field we know what areas to look in or under. We have to utilize several meters to understand what particles we are searching for. Once we narrow down the source we again double check that area with more testing. It’s more like an investigation until we track down the bad particle.

Indoor airborne testing: There are thousands of chemicals that make up CO2 for example. Years ago the EPA said CO2 is not harmful until the PPM count reaches 5000. But understand those chemicals you breath in everyday and long term exposure does cause health issues. We exhale CO2 and so does gas / oil vehicles. Even electric cars! Paints, solvents, refrigeration oils, plastics, rubber and a million other items produce CO2.

Formaldehyde is another very bad chemical. This chemical causes cancer. It can be found in drywall, paints, solvents, carpets, sheets, nail polish and a million other items. EPA says not to exceed .5 PPM.

So when we conduct multiple tests we are looking for thousands of different types dangerous chemicals.

Did you know we have more cancer patients here in the Pacific Northwest than any other part of the country? Radon & Formaldehyde.

Lead Testing

We offer lead-based paint testing for HUD properties as well as construction lead testing. Whether it’s paint inspections, risk assessments and lead clearances, Building Analyst Group can help with wide ranges of lead environmental testing services.

Mold Testing

Mold is one of most common complaints of property owners, managers and tenants. Building Analyst Group uses a scientific approach to perform mold testing in both air and bulk material. Moisture assessments can be performed as well.

Radon Testing..Our radon test only takes 48 hours and you receive a spreadsheet report.

Radon is an invisible, odorless, and carcinogen gas. Building Analyst Group has in-house radon experts that can perform both long and short-term tests throughout West coast. If high radon levels are found, Building Analyst Group assists in the remediation process. 48 hours and you will receive a spreadsheet report on the levels of radon.

Soil Testing

Building Analyst Group has a team that adhere to your property inspections and oversee your soil sampling needs. Whether it’s Geotech or environmental soil sampling, you can rely on our expertise to provide the information you need.


TVOC values reported in the literature are mostly not comparable. To increase comparability, TVOC must be defined clearly. Such a definition is given for a specified range of VOCs. The measured concentrations expressed as mass per air volume of identified VOCs within that range are added. Non-identified compounds in toluene equivalents are included and, together with the identified VOCs, they give the TVOC value. Most reported TVOC-concentrations in non-industrial indoor environments are below 1 mg/m3 and few exceed 25 mg/m3. Over this range the likelihood of sensory effects increases. The sensory effects include sensory irritation, dryness, weak inflammatory irritation in eyes, nose, airways and skin.

  • Formaldehyde  Get an answer in 30 minutes if your home or business has formaldehyde.


The World Health Organization guideline for indoor air formaldehyde concentration is 0.08 ppm (0.1mg/m3). The California Air Resources Board recommends an “action level” of 0.1 ppm and a “target level” of 0.05 ppm or lower for homes. Aside from ALS risk or other nervous system consequences, formaldehyde is a respiratory irritant that causes chest pain, shortness of breath, coughing, and nose and throat irritation, according to the ATSDR. It can also cause cancer, and has been linked to an increased risk of asthma and allergies in kids.Jul 27, 2015

  • CO carbon monoxide is general found in your fossil fuels, however many chemicals are present and provide you with an answer in 30 minutes.

  • CO2 do you know how many types of chemicals that are present in carbon dioxide? We can give you an answer in 10 minutes of the levels of this deadly gas.

PCB Testing

PCB testing is commonly performed on building components and sealants during a demolition. Depending on the type of building, a building survey for regulated materials may need to be performed. Contact us for more information about our environmental testing services.This information applies if you would like to test for the presence of PCBs in a building. Once you have made the decision to test, EPA recommends that you first test the air to determine if building occupants may be exposed to PCBs in the indoor air. This initial step may help prioritize the steps and/or approaches for the renovation or repair work. If you have identified a PCB problem, you will need to characterize it and determine the extent of PCB contamination. It is important to note that even if PCBs are not present in the air, they still may be present in building materials. The commercial production of PCBs started in 1929 but their use has been banned or severely restricted in many countries since the 1970s and 80s because of the possible risks to human health and the environment.

As PCBs are resistant to acids and bases as well as to heat, they have been used as an insulating material in electric equipment, such as transformers and capacitors, and also in heat transfer fluids and in lubricants. PCBs have also been used in wide range of products such as plasticizers, surface coatings, inks, adhesives, flame-retardants, paints, and carbonless duplicating paper.

Chemical Testing

Chemical testing in air and bulk materials is performed when odors cannot be identified in industrial environments to measure potential personal exposure.
