摘要：

One thousand composited particulate samples collected by the National Air Surveillance Network in 1970 on glass fiber filters were analyzed for 24 trace elements by spark-excited direct reading emission spectrometry. Precision data on samples has a median relative standard deviation of 14% for all elements. The median spike recovery was 97%, excluding tin with 11 to 28%. Analysis of different portions of the same filters gave average concentration differences with a median of 14%. Detection limits for all elements and lead analysis by both atomic absorption and optical emission are reported. Zinc and tin data were unacceptable due to poor precision or accuracy.
