Reporte de polen atmosférico durante la estación primaveral de 2007 en la ciudad de San Salvador de Jujuy, Argentina

Resumen

Airborne pollen report during the spring season in the San Salvador de Jujuy city, Argentina. We studied the airborne pollen content during the spring of 2007 in the San Salvador de Jujuy city with the aim to record the qualitative composition, describe the weekly percentual variation of capture pollen, and the evaluation of the representativity of the regional native flora and presence of allergenic pollen. Tthe sampling was carried out with a gravimetric Ddurham trap, with a weekly change of the samples. We identified 36 pollen types of which 17 belong to the exotic vegetation, 14 to the native vegetation from the Yungas forest and 5 of indefinite origin. report shows that, during the sampled period, the airborne pollen content is influenced by the urban vegetation as also the significant contribution of arboreal plants from the native Yungas forest, such as Alnus acuminata, Juglans australis, Celtis sp., Anadenanthera colubrina, among others, while at the end of season the herbaceous pollen are predominant, mainly Amaranthaceae-Cchenopodiaceae and Uurticaceae. Oof the total of pollen types registered, 16 are identified to have allergenic potential; they belong to exotic species present in the urban trees, such as Morus sp., Cupressus sp., Populus sp., Platanus acerifolia, among others, and Celtis sp. of the native flora. Tthe obtained result represents the first aeropalynological study for the San Salvador de Jujuy city.
