Background: The study aims is to determine any relationship between the peak expiratory flow rate and absolute eosinophil count among the cement workers and the non cement workers not exposed to cement in the Guwahati city.

Methods: Peak expiratory flow rate were obtained from 30 cement dust exposed male workers and 30 non cement male workers between 20–40 years using Medspiror (HELIOS) digitalspirometer in the department of Physiology, Gauhati Medical College, Guwahati,Assamand absolute eosinophil count were done by collection of blood samples in EDTA test tube in a improved Neubauer’s chamber.Statistical analysiswas done as Mean±standard deviation.

Results: It was observed that PEFRshowed a significant decrease value and Absolute eosinophil count showed a significant increasevalue among the cement workers.

Conclusions: Cement exposure can lead to respiratory diseases associated with eosinophilia.
