The Differences in the Urinary Phenol Levels between Operators and Administrators at Gas Station in Surabaya

Abstract

Benzene that enters the body will undergo metabolism, will became benzene epoxide in the liver which is an unstable compound and will change the phenol form to excreted in the urine. This study aimed to analyze the differences in urinary phenol levels between operators and administrator officers at a gas station in Surabaya. The method of this analytical study was observation with a cross-sectional study. Research sites were gas
stations of Sisingamangaraja street XIII, Kenjeran Street 99 and Sumatera Street 25. The research conducted from March to July 2014. The population of this study was two populations that were the operator of a gas station and the administrative officers of a gas station in Surabaya with some criteria. Sample size had 22 persons that were taken by simple random sampling, 11 persons from each operator and administration
worker. Data analyzed used independent t-test — the results of this study showed that there were differences in urinary phenol levels between operators and administrators at gas stations in Surabaya (p<0.05). This study concluded that exposure to benzene vapor increased urinary phenol levels. Operators would potentially have higher levels of phenol urine than administrative officers — periodic monitoring of urine phenol levels in the gas station workers in Surabaya to determine intoxication benzene vapor. These results suggest the use of personal protective equipment for workers at filling stations which may include a gas mask, gloves, shoes, and unique clothes. Washing hands after work should make a habit.
