Indoor air constitutes a wide variety of pollutants, exposure levels and different possible health outcomes. In schools, a good indoor air quality is essential to ensure a safe, healthy and comfortable environment for all the occupants, especially children, they being more exposed to indoor pollutants than adults due to their dynamic developmental physiology and immature set of systems. Consequently, in the latest studies, scarce attention has been given to indoor air quality in schools. The main pollutants investigated were the ones derived from fuel combustion, the subsequent emergence of new building materials, glues, paints, furniture, cleaning products and air fresheners; lately, volatile organic compounds caught researchers attention. Also, they concluded that heating, ventilation, and air conditioning, as well as surface cleaning comprise the fundamental operational strategies for adjusting the school environment to improve health and academic performance of students
