Synergie pollen-polluants et rôle des facteurs météorologiques sur le risque de pollinose : évolution des consultations dans la région amiénoise pendant la saison pollinique 2007

The large size of pollen grains could explain the simple relationship between rhinitis and grass pollen, because pollen grains can penetrate only the higher respiratory tract. This effect was not observed for asthma, but a positive relationship between asthma and precipitation suggests a potential role of pollen cytoplasmic granules. Theses granules could massively increase asthma attacks during the pollen season.
