ABSTRACT

Benzene is an organic solvent used in multiple industrial proc-esses. The main objective of the study was to demonstrate the possible effects on erythrocytes, white blood cells and platelets in a group of workers exposed to benzene at a refinery, Venezuela, 2018. It was a descriptive, cross-sectional study, not experimental, in a sample of 29 workers from a refinery in the city of Valencia, Carabobo state. The Mindray BC-5150 hematology analyzer was used, the Theis-Benedict method for phenol in urine, and the Jaffé modified method for creatinine in urine. The objectives and benefits of the study were explained to them through direct contact with the workers. Once their participation was accepted, they signed an infamous consent, to then apply a survey validated by the Center for the Study on Workers' Health (CEST). Significant deference was shown in the platelet count. 28% of the workers presented a decrease in the number of erythrocytes and white blood cells. The levels of urinary phenol in the workers were above the respective biological exposure index (BEI). Prolonged exposure produces a noticeable and progressive effect on platelets.
