For example, allergic rhinitis and sinusitis presents as sneezing, runny nose, tearing, itching of the nose and throat and nasal obstruction. The airborne pollens of spring and fall grasses, weeds, trees, and flowers are well known to us all. Perennial or chronic allergies are due to industrial pollutants, dust, dust mites and animal dander. Allergic conjunctivitis creates itching, red eyes, which can be treated with cold compresses, antihistamines and topical steroids. Allergic dermatitis, eczema and urticaria require special prescriptions from your doctor as does asthma.
Ozone is the major agent in the formation of smog.
It is a bluish, irritating gas of pungent odor formed naturally in the upper atmosphere by a photochemical reaction with solar ultraviolet radiation or by electric discharge in air. Ozone is also a product of arc welding, flour bleaching, deodorizing, emissions from copying equipment and photochemical air pollution. Ozone is a mucous membrane irritant and causes irritation of the nose, throat, eyes and lungs. We at the University Health clinic treat allergy problems everyday.
