摘要：Background. Ambrosia artemisiifolia L. is a noxious invasive alien species in Europe. It is an important aeroallergen andmillions of people are exposed to its pollen.Objective. The main aim of this study is to show that atmospheric concentrations of Ambrosia pollen recorded in Denmarkcan be derived from local or more distant sources.Methods. This was achieved by using a combination of pollen measurements, air mass trajectory calculations using theHYPLIT model and mapping all known Ambrosia locations in Denmark and relating them to land cover types.Results. The annual pollen index recorded in Copenhagen during a 15-year period varied from a few pollen grains to morethan 100. Since 2005, small quantities of Ambrosia pollen has been observed in the air every year. We have demonstrated,through a combination of Lagrangian back-trajectory calculations and atmospheric pollen measurements, that pollenarrived in Denmark via long-distance transport from centres of Ambrosia infection, such as the Pannonian Plain and Ukraine.Combining observations with results from a local scale dispersion model show that it is possible that Ambrosia pollen couldbe derived from local sources identified within Denmark.Conclusions. The high allergenic capacity of Ambrosia pollen means that only small amounts of pollen are relevant forallergy sufferers, and just a few plants will be sufficient to produce enough pollen to affect pollen allergy sufferers within ashort distance from the source. It is necessary to adopt control measures to restrict Ambrosia numbers. Recommendationsfor the removal of all Ambrosia plants can effectively reduce the amount of local pollen, as long as the population ofAmbrosia plants is small
