Abstract

Benzene is a toxic chemical substances, especially against hemopoetic system so that it can lead to either aplastic anemia or leukemia. This study aims to analyze the relationship between exposure benzene to haematological status employee of the gas station in Surabaya. This research was observational analytic study and conducted applying a cross-sectional study. Research sites in the gas station of North Surabaya, South Surabaya, Central Surabaya, East Surabaya, and West Surabaya. The research was conducted from February - August 2011. The population in this study was employees stations in Surabaya with some criteria. Sample size was 28 persons taken at random, 14 persons from each study and control group. Data analysis used two-sample independent t test and multiple logistic regression.Average of benzene measurements obtained at the gas stations in Surabaya did not meet the rhreshold limit value environment based on Minister of Manpower 01/1997 of 10 ppm. Results of phenol in the urine of 6 people was found the respondent had abnormal levels of phenol, while the results of the hemoglobin levels of 7 people was found had abnormal hemoglobin levels. There was a significant association between levels of benzene to phenol urine with p = 0.000 using two-sample independent t test. The results of analysis with multiple logistic regression test was found that the most influential factor (p <0.05) on levels of hemoglobin was urinary phenol level of employees with the odds ratio of 3.278. Its concluded that the higher levels of phenol in the urine then the risk of decline in hemoglobin levels will be higher. Using masks, gloves and long sleeved clothing will help minimize exposure to benzene in gas station employees. The management should provide adequate Personal Protective Equipment (PPE) and regularly carry out health checks on employees.
