Abstract
The Federal Reference Method for photochemical oxidants specified in regulations on National Primary and Secondary Ambient Air Quality Standards is based on the chemiluminescence resulting from the reactions of ozone with ethylene. The method is calibrated by measuring synthetically prepared standard atmospheres of ozone and developing a method response vs. ozone concentration curve. Although the 1% neutral buffered potassium iodide procedure has been used for sometime, it has been criticized for its inconsistent and non-reproducible results. Therefore, a workshop on the problem was held Aug. 26-27, 1974, at NBS facility, Gaithersburg, Md., to bring together individuals with expertise in the use of the potassium iodide method for a full technical discussion of this ozone method of calibration problem. This report presents recommendations and a summary of the discussions held at this workshop.
