Methods
In this retrospective study, we used an active sampling system for measuring the amount of PAHs of air at industrial, high traffic and residential areas in southwest of Iran during the warm (1st September–20th November) and cold (1st December–28th February) seasons of 2016–2017.
Ethical considerations
The Ethics Committee of Ahvaz Jundishapur University of Medical Sciences approved the study protocol. This study was originally approved by the Ahvaz Jundishapur University of Medical Sciences with code IR.AJUMS.REC.1395.492.
Statistical analysis
Sampling and data collection were done by researcher and we analyzed the PAHs data by Excel and SPSS software (SPSS version 16; SPSS Inc., Chicago, IL). We estimated the level of PAHs and compared with national standard of outdoor air at industrial, high traffic and residential areas.
