Background and aims:  volatile organic compounds VOCs are emitted from a variety of sources and production may be impacted harmful to the health, welfare and human performance. No doubt the first step to controlling pollutants are measured and analyzed, because without full knowledge of the quality and quantity of pollutants compared with the limits and the possibilities of their control would not be practical.

Methods: This cross - sectional study was conducted in the chemical industry, dependent on oil. In this study from 18 complexes located in an industrial area about 346 air samples in winter 1391 And 370 samples were collected during the summer in 1392. In this study analyzed 14 volatile organic compound And a sampling from the compounds was performed according to the analysis methods of America National Institute for Occupational Safety and Health (NIOSH). Finally the samples were analyzed by GC-FID and GC-MASS devices. Analysis of the results was performed using spss software version 16.

Results: The mean of the majority of components in all the complex were estimated in summer more than in winter. Also, according to the results demonstrated, the mean ratio of benzene to BTX, BTEX, and total VOC highest percentage (64%) And xylene concentration ratio to these three variables, the lowest percentage (3 to 7%) in both summer and winter.

Conclusions: These results indicate that accumulation of a large number of complexes together and multiple sources of Released pollution in the region of producers increased air pollution in the region. So we are recommended the use of engineering solutions for reducing pollution.
