INFOGRAPHY - The main causes of indoor air pollution

Health effects

Indoor air pollution from one source has harmful effects on health, particularly over the long term. High concentrations of pollutants can cause respiratory problems, irritation, headaches and increased risk of chronic illnesses, including cancer. Children, the elderly and people with respiratory illnesses are particularly vulnerable to the risks associated with poor indoor air quality. Constant exposure to harmful gas emissions, such as carbon dioxide, also contributes to worsening respiratory symptoms and illnesses, depending on the level of exposure at source.

Pollution-emitting activities

The main sources of indoor air pollution come from everyday activities. Tobacco, candles, incense and certain cleaning products emit volatile organic compounds (VOCs), which are dangerous chemical substances with varying levels of emission. In addition, building materials such as paints, glues and products used in renovations release harmful particles and gases into the air. Fuels used for heating, such as wood or fossil gases, are also major sources of pollution. These emissions contribute to a deterioration in indoor air quality, creating a less healthy environment.

Avoiding indoor air pollution: the right thing to do

One of the most effective ways of reducing indoor air pollution is to take simple steps to improve air quality monitoring and management. Airing rooms regularly renews the air and reduces the concentration of pollutants in the air. This is particularly important in poorly ventilated rooms, where moisture and particles can accumulate. Good ventilation is essential for maintaining a healthy environment and reducing the risk of indoor air-related illnesses.

It is also crucial to check ventilation systems and air vents to ensure optimum air flow in the building. The use of air quality detectors makes it possible to monitor pollution levels continuously, alerting occupants when the concentration of pollutants exceeds the recommended threshold. These devices are particularly useful for schools, public buildings and homes, where it is important to protect the health of occupants, especially children.

Finally, it is advisable to avoid using scented products, such as incense and candles, which release chemical compounds into the air. Opting for VOC-free cleaning products and building materials with low pollutant emissions also helps to reduce environmental impact and improve air quality.
