Guide to Finding & Reducing Common Indoor Air Pollutants & Contamination Sources

According to Best Practices Guide to Residential Construction:

Public health officials have focused their efforts on outside air pollution for decades, establishing laws and guidelines for what is acceptable air to breath. As it turns out, however, people spend a lot more time indoors than out and, on average, the air is far dirtier indoors. Pollutants range from the merely unpleasant to the potentially deadly. The health effects of low exposures to many of these substances over long time periods is not well understood.

Yet, it seems prudent to have a working knowledge of what’s in the air you’re breathing and to take commonsense steps to eliminate or minimize materials that, in larger doses, make most people sick.

A summary of common indoor pollutants is shown in

  • Table 7-5, Table of Common Indoor Air Hazards is at INDOOR AIR HAZARDS TABLE provided just below in this document
  • Table 7-9, Table of Combustion Products and Indoor Air Quality is at INDOOR COMBUSTION PRODUCTS & IAQ

For a full discussion of these indoor air hazards see pages 282 and 294 in Best Practices Guide to Residential Construction, by Steven Bliss, Wiley & Sons.

Table of Common Indoor Air Hazards, Contaminants, Pollutants

The following table, issued in three sections, lists common indoor air hazards and contaminants, providing for each contaminant the name, description, primary household sources, health effects, typical exposure levels, and steps to reduce exposure. Below on this page we add corrosive sulphur outgassing from Chinese drywall and a link to odor detection help in buildings.

See COMBUSTION AIR for additional details about the requirement for combustion air. COMBUSTION AIR for TIGHT buildings explains how to provide outside combustion air for tight buildings. See COMBUSTION GASES & PARTICLE HAZARDS for an explanation of the dangers of inadequate combustion air. See COMBUSTION PRODUCTS & IAQ for the relationship between fuel burning appliances and building indoor air quality. More about carbon monoxide - CO - is at CARBON MONOXIDE - CO and at CARBON MONOXIDE WARNING.

Update: to the indoor air quality hazards listed in these tables we add

  • CHINESE DRYWALL HAZARDS discusses Chinese drywall odors, sulphur smells, and corrosive outgassing hazards in buildings. Major costs to remove this product, repair or replace electrical wiring, plumbing, and HVAC components may be involved, and there may be immediate safety hazards due to damaged smoke detectors or carbon monoxide detectors in buildings where Chinese drywall outgassing has caused damage.
