Air Pollution and Increasing Effects on Respiratory Diseases

(Asthma and Allergies)

Research in the Multidisciplinary Respiration Medicine journal has reported on the role that Air Pollution plays in Allergic Respitory diseases.

The researchers, from the Division of Respiratory and Allergic Diseases, High Speciality Hospital A, in Cardarelli, and the Department of Respiratory Diseases, Napoli, Italy note that the incidence of asthma and allergic diseases has increased dramatically during the past few decades and they suggest that the evidence indicates that changes in climate have already affected a diverse set of physical and biological systems in many people.

This is true in both industrialised countries and around the world and the number one risk factor is said to be from the increasing use of cars and lorries.

They also note that allergen patterns are also changing and that air pollution can modify the allergenic potential of pollens especially in presence of specific weather conditions.

They state that the consequences on health vary from decreases in lung function to allergic diseases, new onset of diseases, and exacerbation of chronic respiratory diseases, but that the difficulty lies in the fact that current laboratory measurements don’t reflect what happens when atmospheric pollution mixtures in polluted cities are inhaled.

They also point out that some air pollution-related incidents with asthma aggravation do not depend only on the increased production of air pollution, but rather on atmospheric factors that favour the accumulation of air pollutants at ground level.
