| Summary: | The aim of the present analysis was to describe the dynamics of the <em>Chenopodiaceae / Amaranthaceae </em>pollen in the atmosphere of Timisoara, by taking into consideration the data collected through volumetric method (identification, quantification). <em>Chenopodiaceae / Amaranthaceae </em>has a long pollen season with low concentrations in the air plankton. The period of <em>Chenopodiaceae / Amaranthaceae </em>flowering starts in June and continues until the half of October under climatic conditions from the Western Plain of Romania. The pollen belonging to <em>Chenopodiaceae / Amaranthaceae </em>was sampled during a 5-year (2000-2004) atmospheric pollen-monitoring programme in Timisoara, Romania, using a VPPS 2000 Lanzoni trap. <em>Chenopodiaceae / Amaranthaceae </em>air pollen constitutes between 2.20% and 5.52% of the annual total pollen grains. The highest annual level was attained in 2002 with 1108 PG. Pollen seasons were defined as the periods in which 90% of the total catch occurred. The highest concentration of <em>Chenopodiaceae / Amaranthaceae </em>pollen, equal to 50 PG/m<sup>3</sup>/24 h was identified in 2003. |
