Indoor air quality in aircrafts and possible problems related with IAQ

In this paper, current ECS (Environmental Control Systems) have been studied and the risks have been emphasized regarding to air pollutants, health and comfort within the context of indoor air quality. The factors that influence IAQ in aircrafts are presented : pressure, oxygen, temperature, humidity and air contaminants along with the physiological problems that could be caused by atmosphere such as hypoxia, deep vein thrombosis, transmission of infections.
