Many dty and regional agencies responsible for air pollutant measurements also measure wind and temperature at some of their air pollutant sampling stations. Because exposure at air quality stations is generally considerably less ideal than at airport stations, the data may be representative of extremely local conditions.

Correlations, such as commonly exist between hourly air pollution measurements or wastewater samples taken on successive days, violate the key assumption of the equations in this section. When such correlations exist, alternate methods must be used ( > ) When several characteristics are measured on a sample, the methods of this section can be applied separately for each characteristic. If results for different characteristics conflict, one can pick the result that works best for all parameters or the result for the most important...

The national network of air pollution measurements is keyed to the 247 air quality control regions (aqcr s), which were classified according to the relative severity of their pollution problems. The classification is a ranking of measured ambient air concentrations or the estimated air quality in the area of maximal severity. The priorities for air quality problem severity are as follows ...

PERSONAL MONITORING IS A RELATIVELY NEW CONCEPT in community air pollution measurement research (1-3). This fact is not surprising because most air pollution investigations have been directed toward the characterization of the ambient atmosphere, the observation of pollutant trends, the acquisition of data on chemical kinetic parameters and on the physical properties of aerosols, and the determination of compliance to national and other standards (4). Before the late 1970s, research on personal monitors was primarily conducted in industrial settings (5, 6) because American Confer-... 

Choose an appropriate substitute for the sample matrix. Water would be the choice for essentially aqueous systems. Hydrocarbons pure or mixed distillates, or triglycerides pure or natural oils such as cottonseed or coconut oil would be appropriate substitutes for petroleum- or fat-based systems, respectively. Air or inert gases are appropriate substitutes when air pollution measurements are intended.

Continuous air monitoring for trace contaminants in ambient air has developed extensively since the mid-1960s as a result of stimulation from new air pollution measurement requirements. Workers expect that similar needs will develop as certain chemical constituents of particulate material are identified as factors in human health effects. Techniques for the continuous chemical characterization of particulate matter are slow in coming because the amounts of material sampled are small, often below the detection limits of instrumentation. In all cases so far, either a precollection method like filtration or a special detector of high sensitivity has been required.

The amount of fallout obtained in relatively undisturbed open country is often a surprise to those who have not worked in the area of air pollution measurement. For example, collection of 100 mg of dustfall during a 30-day period by a glass container having a 10-cm-diameter opening, does not sound like much. But in conventional fallout units this amounts to 424mg/m day, or more impressively as 36.4ton/(mile) month (Eqs. 2.2 and 2.3).
