Volatile organic compounds (VOCs) are organic chemicals that have a low vapour pressure and can volatilize into the air. They are emitted by a variety of sources, including cleaning products, paints, varnishes, solvents, furniture and electronics.
These VOCs can have harmful effects on human health, as they can be inhaled and enter our respiratory system. Some VOCs are known to cause eye, nose and throat irritation, headaches, dizziness and even more serious problems such as nervous system damage.
VOCs also play a role in the formation of air pollution, notably smog. When they react with other atmospheric pollutants in the presence of sunlight, they can contribute to the formation of ground-level ozone, a pollutant that is dangerous to human health and the environment.
It is therefore important to take steps to reduce exposure to VOCs, notably by using low-VOC products, ensuring good ventilation in indoor spaces, and limiting the use of chemicals that may emit VOCs.
In conclusion, volatile organic compounds are chemicals emitted by many common sources in our environment. Their presence can have harmful effects on human health and contribute to air pollution. Understanding and reducing our exposure to VOCs is essential to preserving our health and our environment.
