Abstract
OBJECTIVES: This study aims to determine the level of lead in blood of fuel station workers and in a group of people not occupationally exposed to lead METHODS: 53 control subjects with low risk lead exposure and 45 fuel station workers comprising the study group were included in this study in a period from September 2008 to December 2009. Blood samples were collected and analyzed for each subject by Lead Care Blood Testing System. The average blood lead levels of each group were compared using the independent sample (Mann - Whitney U) test. RESULTS: The median (range) 14.1 (7.5-56) μg/dl concentration of lead in the blood of fuel stations workers was significantly higher than the median (range) 6.5 (4.0-1.6) μg/dl concentration of lead in the blood of the control group (p< 0.001).The results obtained also showed that the values of blood lead levels in many workers were higher than action and upper limits acceptable for adults. In fuel station workers, the duration of exposure to leaded fuel was significantly correlated with the blood lead level. CONCLUSIONS: Occupational exposure to lead is prevalent among many fuel station workers in Basrah. A policy action to improve working conditions and to phase out the use of leaded gasoline is recommended.
