CO₂ is a colourless gas produced by human respiration and combustion processes (such as burning fossil fuels).
Elevated CO₂ levels indoors can affect cognitive function, concentration, and overall comfort. Proper ventilation ensures fresh outdoor air circulation, maintaining safe CO₂ levels.
Volatile Organic Compounds (VOCs) are chemicals emitted from various indoor sources, including paints, cleaning products, furniture, and carpets.
These compounds can impact both health and indoor air quality, including liver damage, lung damage and cancer in serious cases
Strategies to reduce VOC exposure include using low-VOC materials, proper ventilation, and choosing products with minimal emissions.
Formaldehyde is a common indoor pollutant found in building materials, furniture, and household products.
Prolonged exposure to formaldehyde can cause respiratory irritation, headaches, and other health issues.
Proper ventilation and selecting low-formaldehyde products are essential for minimising exposure.
Ozone is a gas formed by chemical reactions (e.g., from air purifiers or photocopiers).
While ozone high in the atmosphere protects us from UV radiation, indoor ozone can harm respiratory health. Limiting exposure to safe levels is crucial.
NO₂ is produced by combustion processes (e.g., gas cookers, vehicles). Indoor exposure to NO₂ aggravates respiratory conditions, especially in individuals with asthma.
Proper ventilation and minimising indoor combustion sources help reduce NO₂ levels.
Radon is a naturally occurring radioactive gas that seeps into buildings from soil and rock.
Long-term exposure to radon increases the risk of lung cancer.
Radon testing is crucial, especially in areas with high natural radon levels.
CO is a colourless, odourless gas produced by incomplete combustion (e.g., gas cookers, fireplaces, or car engines).
CO poisoning can be fatal. Installing CO detectors and ensuring proper appliance maintenance are essential safety measures.
