The variables studied were the concentration of benzene in the air, erythrocytes, hemoglobin, and health complaints among workers at Printing X Surabaya. Data analysis using Spearman rank correlation test. Measurement of the concentration of benzene in the air exceeds the Threshold Limit Value. There were 5 respondents had erythrocyte level above the normal and 1 respondent had hemoglobin level below the normal. There was a quite significant and positive relationship between the concentration of benzene in the air and erythrocytes (p=0.033). But there was no significant relationship between the concentration of benzene in the air and hemoglobin (p=0.158).
