Natural Health News – Two air pollutants associated with climate change could also be an important unprecedented increase in the number of people sneezing, runny nose and wheezing during allergy season factor.
The gases, nitrogen dioxide and ozone at ground level appears to cause chemical changes in certain airborne allergens that could increase their power. That, in combination with changes in the global climate, could help explain why airborne allergies are becoming more common. The findings were presented at a recent annual Meeting and Exposition of the American Chemical Society (ACS). National
Nasal allergies are increasing worldwide. Scientists have long suspected that air pollution and climate change are involved in the increased prevalence of allergies. But understanding the underlying chemical processes behind this phenomenon has been difficult to achieve. The current research provides a starting point in understanding how chemicals can affect the allergenic potential of substances in the air.
In previous work the Max Planck Institute researchers explored how the substances that cause allergies are altered in the air. From that work, they decided to dig deeper into how that happens and examine how air pollutants related to traffic can increase the dose of these allergens.
In laboratory tests and computer simulations, the researchers found that ozone (a major component of smog) an amino acid that triggers chemical reactions that alter the final structure of an allergenic protein is oxidized. Meanwhile, nitrogen dioxide (which is in exhaust) appears to alter the separation and binding capacities of certain allergens.
believe that together, the two gases cause the most likely to trigger the body’s immune response, especially in wet, humid and smoggy conditions allergens.
In future research the team hopes to identify other allergenic proteins are modified in the environment and examine how they affect the human immune system.
