Pollen concentration in the atmosphere in the Algarve with high risk
The district of Faro, in the Algarve, and the area of Castelo Branco, in Beira Interior, will have a high risk of pollen in the atmosphere from today, announced the Portuguese Society of Allergology and Clinical Immunology ( SPAIC ) on Thursday, May 8.
According to SPAIC, the rest of the continent will have a low to moderate risk and in the autonomous regions of Madeira and the Azores the forecast is that it will be low, in the week between May 9th and 15th.
In the regions of Vila Real, Entre Douro e Minho, Beira Litoral, Lisbon district and Alentejo, the forecasts are for low or moderate risk.
According to SPAIC, the pollen grains observed in the atmosphere come mainly from olive, pine, birch, cork oak and oak trees and from grasses, plantain, sorrel, nettle and urticaceae (including pellitory).
The period from February to October is the one with the highest total concentrations of pollen, with peaks occurring from April to July.
Pollens from grasses, trees and shrubs are usually the most important inducing agents of allergic symptoms.
