This study reports the indoor ozone (O3) pollution in the rural location of Kannur, a tropical site in India, during March 2018 and the influence of their most important determinants. Measurements of indoor O3, NO, NO2 and NOx were carried out in a residential building for a period of one week. Measurements were taken from the kitchen, as it had been identified as the most polluted spot. The background concentrations of O3, NO, NO2 and NOx were also monitored. Indoor O3 originates mainly from the outdoor environment and is also produced from indoor sources. The results show that there is a higher level of indoor O3 during cooking hours. The study indicated that cooking activities in the kitchen had a strong impact on the indoor O3 level. Ozone is an important gaseous pollutant which may lead to severe health problems such as decreased lung function and respiratory symptoms.
