Biomass use in small unit combustion systems such as for space heating or cooking could lead to ineffective mixing and potential problems arising from emissions of gaseous and particulate pollutants. We therefore conducted a study to measure pollution levels in public kitchens using biomass fuel for cooking and to ascertain their air quality indices. Markers of indoor air quality such as CO, SO2, H2S, PM2.5 and PM10 were measured in eleven (11) public kitchens of selected secondary schools over a period of four months by a set of active sampling devices. It is revealed that the mean average of CO, SO2, H2S, PM2.5 and PM10 sampled in the indoor microenvironments of the selected kitchens are 46.29 ppm, 0.36 ppm, 0.28 ppm, 74 µg/m3 and 138 µg/m3, respectively. The AQI assessed for CO for the kitchens was 36.36% very hazardous, 54.54 % hazardous and 9.09% very unhealthy while 63.64% and 36.36 % of very unhealthy and unhealthy categories, respectively for SO2. This shows that the indoor air pollution levels in selected kitchen are elevated and results in potential negative health consequences.

The problem of air pollution has ramifications for human health, the environment, and a variety of living sectors. Modern technology has resulted in air pollution and its damaging effects, while also driving the world to make every effort to overcome its negative repercussions. The origin, chemical composition, size, and mode of discharge inside or outdoor environments have all been proven to be air pollutants. Industrial, commercial, mobile, urban, regional, farm, and natural sources of indoor pollutants include cooking and combustion, particle matter rehabilitation, materials used for resources, temperature control, and consumer items, smoking, heating, and organic compounds. Indoor Pollutant Sources Air pollution has an impact on the body, including respiratory systems and heart disorders. Asthmatics, bronchiolitis, lung disease, cardiovascular problems, central nervous system malfunction, and skin conditions are the most common respiratory disorders, as are chronic obstructive pulmonary disease (COPD). The challenges posed by outdoor air pollution are public health risks such as cardiovascular disease, respiratory ailments, COPD, and world-class asymmetry. The impacts of human activities on air quality and climate change may be realized at several sizes, ranging from urban to regional to continental to global. Rapid population growth and increased energy consumption are the principal drivers of massive amounts of hazardous chemicals and greenhouse gases entering the atmosphere, with serious consequences for health and the environment.
