Methods and instruments for measuring indoor air quality are described. The major pollutants or classes of pollutants covered are carbon monoxide, nitrogen dioxide, respirable particles, formaldehyde, volatile organic chemicals, pesticides, polynuclear aromatic hydrocarbons, and radon. A brief discussion of a new method for collecting house dust is also included.
In most cases, the methods described have been developed specifically for measuring either indoor air or personal exposure; they are not simply existing methods adapted from ambient (outdoor) use. Generally such existing outdoor air methods are unsuitable on grounds of bulk, noise, excessive air flows, and other problems.
The authors conclude that a complete set of methods allowing both short-term peaks and long-term averages to be measured presently exists for very few, if any, of the major pollutant groups. Thus it will be necessary to have vigorous methods development programs in the public and private sectors if we are to make progress in understanding the magnitude of the indoor air quality problem.
