Results: The results of this study shows that the average job stress groups were 45.01, And statistically significant relationship between the deleterious effects of job stress is noise and dust (P <0/01). But between job stress and other harmful elements such as lighting and thermal stresses not found. Job stress also with regard to age, experience, and the difference in their activity there. 

Conclusion: According to the result can be inferred the noise and dust in the workplace occupational, affecting factors on workers job stress in the production line workers in the cement industry. Also, With increasing age, job stress increases. On the other hand, those with a history of activities in which the burden is too much for them and This leads to increased stress. In different units of Cement production line, the intensity and duration of exposure to harmful factors is vary, That this causes differences in job stress with respect to their activities on the site.
