摘要：

A simple, inexpensive integrated sampling method using a glass syringe has been developed for air pollution measurements. The syringe is mounted vertically so that the weight of the plunger provides a constant suction to a Teflon capillary of 20-500 cm length. Uniformity and reproducibility of sampling rate are easily attained with most commerical syringes. Sampling duration from 5 to 60 minutes can be predetermined from the dimensions of the capillary using the Hagen-Poiseuille equation. The method was tested both indoors and outdoors and found to be useful for routine air sampling.
