Popis:	Ambrosia arrived in Hungary from northern Mediterranean in the 1920s, and by the end of the 20th century it has become widely distributed. In Southern Hungary (northern part of Serbia‐Montenegro included), Ambrosia pollen concentrations during the peak season are about one order of magnitude higher than the counts in the rest of Europe. The aim of the study is to survey the history of Ambrosia in the Carpathian Basin and analyse some Ambrosia pollen characteristics (season start, duration, average diurnal count and total count) focusing on a medium‐sized city, Szeged, Southern Hungary. The data consists of daily Ambrosia pollen counts for the 15‐year period between 1989 and 2003. Although Ambrosia pollen counts fluctuate considerably, no significant trends can be detected in their temporal course. According to the Makra‐test, the highest pollen counts in Szeged are detected between 20 August and 11 September. This period is in good correspondence with both days comprising over 50 pollen grains per m3, and...
