Interlaboratory Cooperative Study of Air Quality Measurement Methods
N DS55S5S6S8
Annotation
This report presents the results obtained from an experimental study of the accuracy and precision of measurements of particulate and vaporous lead using a colorimetric dithizone procedure as described in ASTM Method D-3112 (*). Measurements of lead concentration in spiked and unspiked atmospheric air samples were performed by eight participating laboratories at three test sites: Los Angeles, California; Bloomington, Indiana; and New York, New York. The first series of field tests were conducted at the University of Southern California on August 15-21, 1971; the second series of field tests were conducted at Indiana University on October 24-30, 1971; and the third series of field tests were conducted at Cooper Union (New York City), on January 9-15, 1972. All measurements were made according to a tentative ASTM method for lead in the atmosphere from which ASTM Method D 3112(6)* evolved.
This report describes the experimental testing program, gives a complete tabulation of the experimental data used in the statistical analyses, and presents estimates of accuracy and precision of the lead method derived from the test results.
(*) This study was funded by the American Society for Testing and Materials as part of a larger experimental program designated Project Threshold that involved the sampling of other atmospheric contaminants (nitrogen dioxide, sulfur dioxide, dustfal, total sulfation, and particulate matter).
