Air pollution worsens the impact of polen for alergies

In order to protect themselves from the increasing air pollution, plants produce more allergenics. At the same time, ozone and nitrogen oxides and sulfur dioxides irritate the human mucous membrane, making it more sensitive to allergenics, according to researcher Claudia Traidl-Hoffmann from the Technische Universität in Munich. Hazardous substances in the air do not only cause allergies, they also increase the risk of getting asthma. Fine dust are specially dangerous, particularly for children.
