Abstract
Currently, people worldwide, in the period from September to April, observe with their own eyes and feel the pollution of the air, called smog, in their own breath. The biggest cause of smog and the source of air pollution is burning rubbish in stoves. Other causes include exhaust fumes from large factories, burning coal in furnaces, and car exhaust fumes. Smog is an unnatural phenomenon, directly related to human activity. The weather is becoming worse. On no-wind, foggy days, the smog phenomenon is the most troublesome for city dwellers. Smog persists in European countries from November to April, during the heating season. The harmful effect of smog affects almost the entire human body. Every year, air pollution causes the death of approximately 26,000–48,000 people. At the same time, poor air quality reduces life expectancy by up to a year. The purpose of this article is to present buildings and finishing elements that can help in the fight against air pollution.
Highlights
Combustion products contributing to low emissions include the following gases: carbon dioxide (CO2 ), carbon monoxide (CO), sulphur dioxide (SO2 ), nitrogen oxides (NOx ; NO2, NO), polycyclic aromatic hydrocarbons such as benzo(α)pyrene and dioxins, and heavy metals and particulate matter (PM10 and PM2.5)
Thanks to its self-purifying properties, i.e., the conversion of organic compounds, sulphur, and nitrogen oxides into harmless substances, i.e., water and CO2, titanium dioxide makes it possible to clean the air of pollutants [32]
The nano-additive is not applied to the tile itself, but they are coated with an impregnation with photocatalytic properties
Summary
Los Angeles-type smog [9,10], otherwise known as photochemical smog, occurs during the summer months of the year and usually in subtropical areas Under such conditions, under the influence of strong sunlight, the chemical compounds contained in car exhausts are strongly transformed and oxidants are formed. Combustion products contributing to low emissions include the following gases: carbon dioxide (CO2 ), carbon monoxide (CO), sulphur dioxide (SO2 ), nitrogen oxides (NOx ; NO2 , NO), polycyclic aromatic hydrocarbons such as benzo(α)pyrene and dioxins, and heavy metals (lead, arsenic, nickel, cadmium) and particulate matter (PM10 and PM2.5).
