There is an indication that air pollution is measured, but I was unable to find data online. It is among the basic missions of the National Agency for Environmental Protection (NAEP) to preserve and improve the quality of our nation's air. In order to accomplish this mission, the Agency must be able to evaluate the status of the atmosphere compared to clean air standards and historical informations. That's why the NAEP established since 1996 an Air Quality Monitoring Network (AQMN) composed by thirteen permanent monitoring stations, two mobiles laboratories and a data elaboration centre with the aim of characterizing human health exposure and public impacts of conventional pollutants. https://www.researchgate.net/publication/274076911_Tunisian_Air_Quality_Monitoring_Network_Presentation Water and air pollution stats seem to be published by the statistical institute https://www.ins.tn/en/themes/environnement but there is no data available.
