This article considers issues related to air pollution in residential apartments equipped with gas stoves. The combustion products from gas stoves are released directly into the indoor air, where people can spend a significant part of their time. Even relatively low concentrations of harmful substances contained in combustion products can pose serious health risks and potentially threaten lives. The detrimental effects of nitrogen oxides (NOx) on human health and the environment are briefly analyzed. A comparison and analysis of legal regulations and standards regarding the maximum permissible concentration of NOx in the air across various countries are conducted. Theoretical calculations estimating the potential NOx levels in gas-equipped kitchens are presented. Additionally, the results of experimental studies measuring the NOx concentrations in the air of apartments with different gas stove designs, burner types, and ventilation methods are presented. The authors’ data are compared with existing data from other similar studies.
