LOW TEMPERATURE SO~2 SAMPLING BY PASSIVE SAMPLERS IN A NORTHEASTERN CHINESE INDUSTRIALIZED AREA

摘要

Due to its reliability, simple and portable structure and low costs, the passive sampler is the ideal measuring device for developing countries. In spite of this, there has been no reporting on its reliability in extremely low temperate areas such as those associated with Northeastern China. The measuring of SO_2 by passive samplers was attempted at extremely low temperatures in the heavy industrialized area of Shenyang, China from December 25 to 28, 1995.
