The Connection Between Pollution and Allergies
Rhinitis, conjunctivitis, asthma attacks, and other respiratory issues are common symptoms for people allergic to pollen, and thes are exacerbated during periods of air pollution. In France, these allergies impact one in four individuals.
The Seine-Maritime department recently experienced a pollution peak due to high concentrations of fine particles. This harmful atmosphere compounds the persistent air pollution from ozone, nitrogen oxide, and other pollutants.
Chronic exposure can have severe health consequences, especially for vulnerable or allergic individuals.
While one isn’t strictly “allergic to pollutants,” pollution acts as an aggravating factor for allergies. Elsa Rosolen, a pediatric pulmonologist at the Groupe Hospitalier du Havre and CHU de Rouen, explains.
Hazardous Particles During Pollution Peaks
According to Elsa Rosolen:
Sur le pic de pollution de ces derniers jours,il s’agit des fines particules,qui ont un diamètre assez fin. Là c’est moins de 10 micromètres, mais il y en a même de moins 2,5 et ainsi de suite… En fonction du type de particule et de sa taille notamment et sa nature,il y aura une dangerosité plus importante sur les voies aériennes. Elles rentrent plus profondément et vont avoir des effets nocifs.

How Pollution aggravates Allergies
Elsa Rosolen clarifies the relationship between pollution and allergies:
Bien sûr, on n’est pas allergique à la pollution. Mais le problème c’est que l’on va avoir des muqueuses irritées par la pollution, elles vont être plus perméables,

Understanding the link Between Air Pollution and Pollen Allergies
Are you experiencing worsening allergy symptoms during periods of high air pollution? You’re not alone. This Q&A explores how air pollution intensifies pollen allergies, offering insights and practical advice.
Frequently Asked Questions
How does air pollution affect pollen allergies?
Air pollution doesn’t cause allergies, but it significantly aggravates them. Pollutants irritate the mucous membranes, making them more permeable to allergens like pollen. This increased permeability leads to heightened allergic reactions such as rhinitis,conjunctivitis,and asthma attacks.
What is allergic rhinitis?
Allergic rhinitis, often caused by pollen, is inflammation of the nasal passages. Symptoms include sneezing, a stuffy or runny nose, itchy eyes, and throat irritation.
Is there an allergy to air pollution?
No, you cannot be strictly “allergic” to pollution.Instead,pollutants act as irritants that exacerbate existing allergies,especially pollen allergies. This is due to the irritation and increased permeability of the mucous membranes.
What types of air pollutants worsen pollen allergies?
Key pollutants that aggravate pollen allergies include:
- Fine particulate matter: Especially particles with a diameter of fewer than 10 micrometers (PM10) and even more so those less than 2.5 micrometers (PM2.5).These particles can penetrate deeply into the airways, causing significant harm.
- Ozone: A gas formed by the reaction of sunlight with pollutants like nitrogen oxides and volatile organic compounds.
- Nitrogen oxides: Gases produced by vehicle emissions and industrial processes.
What are common symptoms of pollen allergies exacerbated by pollution?
Symptoms include:
- Rhinitis (inflammation of the nasal passages)
- Conjunctivitis (inflammation of the conjunctiva of the eye)
- Asthma attacks
- Breathing difficulties
Who is most at risk from the combined effects of pollution and pollen?
Vulnerable individuals, such as children, the elderly, and those with pre-existing respiratory conditions (like asthma), are most at risk.Allergic individuals are also particularly susceptible to worsened symptoms during pollution peaks.
Where in France is this issue particularly relevant?
Cities like Le Havre and Rouen in the Seine-Maritime department have experienced pollution peaks that worsen pollen allergy symptoms.
What can I do to protect myself during periods of high pollution and pollen?
