PM2.5 can irritate the respiratory tract, potentially
intensifying allergic reactions on days with high pollen
and PM2.5 levels.
Particulate Matter 10 (PM10)
Good (Good μg/m^3)
Unlike smaller particulates, PM10's interaction with
mucous membranes can lead to immediate irritation,
amplifying an allergic response.
Ozone (O₃)
Good ( ppb)
Ozone, when inhaled, can cause direct oxidative damage
to lung tissue. This can lead to inflammation,
increasing the vulnerability of the respiratory tract to
allergens such as pollen.
Nitrogen Dioxide (NO₂)
Good ( ppb)
Emitted primarily from vehicle exhausts and industrial
combustion processes, NO₂ can intensify the body's
inflammatory response, magnifying the severity of
allergic symptoms.
Carbon Monoxide (CO)
Good ( ppm)
When CO binds with hemoglobin in the blood, it reduces
oxygen supply, potentially intensifying fatigue and
breathlessness.This may hinder quick recovery from
allergic episodes.
Sulphur Dioxide (SO₂)
Good (Good ppb)
For those dealing with inflammatory effects of pollen
allergies, direct inhalation of SO₂ can exacerbate
symptoms, such as wheezing, shortness of breath, and
coughing.
