[Inhalation of gasoline and damage to health in workers at gas stations].

The aim of this study was to made assessment of chronic health effects in 37 workers exposed to gasoline, and its constituents at gasoline stations between 1985 and 1996. By the study we have involved thirty-seven persons who had been exposed to gasoline for more than five years were examined. The evaluation included a medical/occupational history, hematological and biochemical examination, a physical exam, standardized psychological tests, and ultrasound examination of kidneys and liver. The groups were identical in other common parameters including age, gender (all men), and level of education (P < 0.05). The data were compared to two control groups: 61 gasoline unexposed controls and 25 workers at gasoline stations exposed to organic lead for only nine months. Peripheral smear revealed basophilic punctuated eritrocytes and reticulocytosis. We found in chronic exposed gasoline workers haematological disorders: mild leukocytosis (7 of 37), lymphocytosis (20 of 37), mild lymhocytopenia (3 of 37), decrease of red blood cells count (11 of 37). Results indicated that they have suffered from liver disorders: lipoid degeneration of liver (14 of 37), chronic functional damages of liver (3 of 37), cirrhosis (1 of 37). Ultrasound examination indicated chronic kidney damages (8 of 37). These results significantly differed from those of controls (P < 0.05). In 13 out of 37 workers at gasoline stations exposed to gasoline for more than 5 years the symptom of depression and decreased reaction time and motor abilities were identified. The summary of diseases of workers exposed to organic lead and gasoline are discussed.
