Sažetak

In recent years Zagreb city encounters severe pollution problems in aquatic, terrrestrial and atmospheric environment. A random or permanent monitoring of some inorganic gaseous pollutants in atmosphere has already been organized and published alsewhere. By means of a sophisticated mercury vapor analyser with a Zeeman effect background corrector, however, continuous registration along two traverses (monitoring routes) over rural, urban and industrial parts of Zagreb has been elaborated for the first lime. Data show strong anthropogenic influence in the Žitnjak industrial area. The anomaly high 105 ngm Hg, on the 22 October moved slightly to downtown by change of wind direction on the 31 October. Intensity raised as much as 155 ngm Hg, 13 times augmented in comparison to a background value on the Medvednica mountain. Explanation should be sought in denser public traffic, change of wind direction and lowering of atmospheric pressure.
