摘要：

Hot gases of volcanic origin (fumaroles) were sampled by means of an activated charcoal filter. The charcoal was specially prepared by a high temperature - vacuum treatment. Mercury, arsenic, bromine, antimony and selenium were determined by activation analysis and compared with literature values. A lightweight pumping station was developed to enable transport to the crater regions of Stromboli and Vulcano. The teflon membrane pump is driven by wind. The filter unit, a specially shaped quartz glass tube, was lowered into the hot vents. The temperature of the sampled fumaroles was 100 to 330-degrees-C.
