Resumen:
A pollen analysis was carried out on six herbaceous pollen types whose annual concentration represents a
percentage higher than 0.3% in the atmosphere of the city of La Plata, Argentina, from July 1998 to June
2001. They are: Ambrosia, Cyperaceae, Chenopodiaceae-Amaranthaceae, Plantago, Poaceae and Urticaceae.
Hourly patterns of the pollen types analysed with the intradiurnal daily index (IDI) could be grouped into
three categories account the percentage that represent of pollen concentration registered during five hourly
periods of the day. Group I includes pollen types that show a sharp peak in abundance gust one at hour of the
day. Group II is formed by pollen types that show high concentrations in more than one hourly band during
the daylight. Group III is characterized by the pollen types that show lower concentrations over a broad
hourly band during the day.Ambrosia, Cyperaceae, Chenopodiaceae-Amaranthaceae, Plantago, Poaceae and Urticaceae.
