Thousands of factories and billions of vehiclesrelease enormous amounts of pollutants into the air everyday; dangerously affecting human health. Many epidemiologicalstudies pointed out the responsibility of air pollution in manyhealth issues, the reason why monitoring air quality becamean obligation to prevent or limit these issues. Conventionalsystems based on measuring stations are expensive and offerlow data granularity. As a result, researchers are increasinglytargeting IOT-based systems. However, elaborating a new systemfor air quality monitoring requires an awareness of the stateof the art and the mastery of a certain amount of specificknowledge (pollutants, their health effects, the sensing equipment,the IOT possible configuration,...).This paper aims to answerthese necessities by reviewing the existing works on air qualitymonitoring using IOT with the focus on lasted trends andchallengesenInternet of ThingsAir PollutionAir Quality MonitoringPollution and HealthOther
