摘要：Microscopic solid or liquid matter suspended in earth's atmosphere is definition atmospheric particulate matter. Particles with diameters that are generally 10 micrometers and smaller (PM10) are one of the main components of indoor and outdoor air quality that can very dangerous for humans. The purpose of this study was to assess the PM10 of the outdoor air in in Ahvaz outdoor air at industrial, high traffic and residential areas during the warm and cold seasons of 2017. Data collected was performed by used active sampling system. High volume air samplers and equipped with quartz filters were utilized for sampling in this study. In this study for determine and analyzed the effects of PM10 during warm and cold season was used to Statistical software SPSS version 16. The results show that the average PM10 concentration in cold and warm season were 156 and 139 ^g/m3, respectively. Result of this study showed the mean of PM10 concentration in cold season was significantly higher than standard. Also, according to results level of PM10 during cold season were higher than the warm season. We can reduce the exposed to PM10 in outdoor air by increase environmental monitoring, decreasing PM10 in source and increase knowledge.
