Summary
Marine engineers exposed to mineral oil mist showed slight lung function impairment and increased chest X-ray abnormalities. This study highlights potential occupational health risks for seamen working in engine rooms.
Area of Science:
- Occupational Health
- Pulmonary Medicine
- Radiology
Background:
- Marine engineers face chronic exposure to mineral oil mist in ship engine rooms.
- Previous research indicates potential respiratory and radiographic health effects in this cohort.
Purpose of the Study:
- To assess lung function disturbances in marine engineers.
- To identify chest X-ray abnormalities in marine engineers exposed to mineral oil mist.
Main Methods:
- Chest radiographs from 68 marine engineers and 101 controls were analyzed using the International Labour Organization (ILO) classification.
- Spirometric data, including forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), were collected from 44 engineers and 71 controls.
Main Results:
- A statistically significant increase in "any symbol" findings on chest X-rays was observed in engineers (9.3%) compared to controls (0.6%).
- Engineers exhibited a slight but significant decrease in FEV% (FEV1/FVC x 100) compared to controls (P = 0.03).
Conclusions:
- Marine engineers exposed to mineral oil mist demonstrate a mild impairment in lung function.
- The study indicates an elevated prevalence of chest X-ray abnormalities, excluding small opacities, among marine engineers.
