在森林和偏远地区采集的空气样本中，查明并确定了100多种天然和人为来源的挥发性有机化合物。碳吸附捕集器和高分辨气相色谱-质谱联用技术的结合使用，使得有机酸、醇类和羰基化合物等极性化合物的选择性离子检测成为可能。北方欧洲、地中海盆地和喜马拉雅地区记录的挥发性有机成分的分布和组成之间的比较似乎表明，一些生物起源的极性有机化合物无处不在。意大利国家研究理事会在珠峰脚下建造的意大利站进行的测定清楚地表明，在有利的条件下，大量的人造有机污染物可以被输送到未受污染的地区。
More than 100 volatile organic compounds of natural and man-made origin were identified and determined in air samples collected in forest and remote areas. The combined use of carbon adsorption traps and high-resolution gas chromatography-mass spectrometry made possible the selective determination of polar compounds such as organic acids, alcohols and carbonyl compounds by selected-ion detection. A comparison between the distribution and composition of volatile organic components recorded in Northern Europe, the Mediterranean basin and the Himalaya region seem to be indicative of the ubiquitous occurrence of some polar organic compounds of biogenic origin. The determinations carried out in the Italian Station built by the National Research Council (CNR) of Italy at the foot of Mount Everest show clearly that, under favourable conditions, substantial amounts of organic pollutants of man-made origin can be transported over unpolluted areas.
