Background and aims   Beside the vast usages of styrene in different industries, this compound can be considered as an important organic air pollutant. Styrene, in one hand, can adversely affect on workers and on the other hands can cause air pollution in the environment. In this study, Tabriz Petrochemical Complex was selected for evaluation of styrene.   Methods   Measurements were performed separately in production lines of olephin and styrene and sampling sites were selected randomly in both olephine and styrene lines. For evaluation of styrene, occupational sampling was performed based on method number 834 recommended in the book "Air sampling analysis". The method was extended using some correction factors. Sampling  process was performed in seasons Summer and Autumn. To draw isoline curves of Pollution,   Surfer software version 504 was used.    Results & Conclusion   The results showed that, there were no significant difference between concentration of pollutants and seasons. Agreement between styrene concentration and prailing winds showed a significant difference between styrene and prailing winds.
