Explanation:

Allergies are increased immunological reactions against an antigen, so I added to your question that ambrosia pollen generates more allergies in the respiratory tract than at the cutaneous level, that is why it cooperates with other alterations that environmental contamination generates.

The greater the contamination, the greater the presence of allergies or the longer the allergies will be.
