Pollutants now
concentration · sub-indexWhat it isPM2.5
Fine particles under 2.5 µm — small enough to reach the lungs and bloodstream. They come from wildfires, diesel engines, industry and smoke, and are the pollutant most linked to heart and lung disease.
WHO 2021 guideline: 15.0 µg/m³ (24-h mean)What it isPM10
Inhalable particles up to 10 µm: road and construction dust, pollen, soot and sea salt. They irritate the nose, throat and airways and worsen asthma and bronchitis.
WHO 2021 guideline: 45.0 µg/m³ (24-h mean)What it isOzon (O₃)
Ground-level ozone forms when sunlight reacts with vehicle and industrial gases. It peaks on hot, sunny afternoons and causes coughing, chest pain and reduced lung function during exercise.
WHO 2021 guideline: 100 µg/m³ (24-h mean)What it isStickstoffdioxid (NO₂)
A gas produced mainly by fuel burning in cars, trucks and power plants. Highest near busy roads. It inflames the airways and increases asthma attacks.
WHO 2021 guideline: 25.0 µg/m³ (24-h mean)What it isSchwefeldioxid (SO₂)
A gas released by burning coal and oil in industry, refineries and ships. It irritates the eyes and airways; people with asthma are especially sensitive.
WHO 2021 guideline: 40.0 µg/m³ (24-h mean)What it isKohlenmonoxid (CO)
A colourless, odourless gas from incomplete combustion — vehicle exhaust, stoves and fires. It reduces the blood's ability to carry oxygen and is dangerous in enclosed spaces.
WHO 2021 guideline: 4000 µg/m³ (24-h mean)Tap a day to see it hour by hour
