It is important for each of us that the environment in which we live, work and spend our leisure time is clean and not harmful to health. On average, eight percent of our planet’s population lives in areas that are constantly experiencing the contamination of even several species at once. One of the main pollution problems we all face is air pollution. Persistent exposure to polluted air is associated with an increased risk of asthma, lung, heart disease and cancer. Bad weather also affects a person's mental state.
No special knowledge is required to know if the environment around us is clean. When the level of air pollution is critical, it becomes difficult to breathe, an unpleasant odor is felt, and a bitter taste may appear in the mouth. Prolonged inhalation of dirty air may cause headaches and other symptoms. It is not so easy to identify lower levels of air pollution. However, we can make sure the air is clean even by observing nature. So-called clean nature indicators such as lichens simply do not grow in a polluted environment. The Environmental Protection Agency takes care of the regular provision of information on air pollution in Lithuania. In order to minimize the risk to human health from pollution sources, the Agency provides regular data on the country's air quality. The content of pollutants in the air, such as general dust, sulfur dioxide, carbon monoxide, sulphates, etc., is measured. Detailed information on air quality in your area can be found on the Agency's website.
When it comes to indoor air, its quality is determined by a variety of factors. Various chemicals can be released from finishing materials and furniture of unnatural origin. Household cleaners can emit volatile organic compounds. If the premises are fired with solid fuel, we inevitably inhale the products of fuel combustion. If there are smokers in the family, we breathe in tobacco smoke. We can bring various viruses, bacteria and mold spores from the field. It’s all in the air around us, and that’s what we breathe.
Statisticians spend as much as 80% of their time indoors, so quality indoor air becomes more important than outdoor air quality. If we cannot choose the air in the open, we are fully able to control the air quality in the home. Even living in sufficiently contaminated areas can reduce the amount of inhalable pollutants. Rational ventilation of the premises plays the most important role here. Usually, most people ventilate the rooms through the windows, but such ventilation has some obvious disadvantages. First of all, the internal heat of the premises is lost during the cold season. Secondly, pollutants also enter the premises with fresh air. Modern ventilation units with recuperation become a rational solution in this situation. In homes with such a system, clean air enters and polluted air travels outside. This creates a particularly healthy indoor microclimate, preventing mold and dust that can irritate the airways. If we care about the food we eat, the beauty products we use for our bodies, why ignore the air we breathe every day?
