RESUMEN

For its toxicity, benzene exposure is one of the main health concerns for high risk occupations like gasoline station workers. However, there is little knowledge about the effect of benzene metabolites on hematological parameters. To evaluate the correlation between the urinary level of trans, trans-muconic acid [t, t-MA], a benzene metabolite, and some hematological parameters in gasoline workers. We studied 102 gasoline station workers from 11 gasoline stations in Pathumwan district, central area of Bangkok, Thailand. Their blood and urine samples were analyzed for some hematological parameters and urinary t, t-MA analysis by high performance liquid chromatography [HPLC]. We found an inverse correlation between urinary t, t-MA concentration and hemoglobin level [r = 0.281, p<0.05], hematocrit [r = 0.264, p<0.05]. Those with higher urinary t, t-MA had a significantly [p<0.05] lower eosinophil counts than those with lower exposure. No significant correlation was found between urinary t, t-MA level and other white blood cell parameters and platelets count. Exposure to benzene would cause bone marrow depression presenting as drop in hemoglobin, hematocrit and eosinophil counts
