||The objective of this cross-sectional study was to evaluate occupational respiratory hazards among 346 pit diggers in Agadir, Morocco, and its surrounding region. The survey covered working conditions, physical and chemical soil analyses and a medical assessment (questionnaire, clinical examination, spirometry and chest X-ray). The study population consisted exclusively of male workers with a mean age of 42.8±10.5 years and a mean duration of exposure of 14.5±6.9 years. 50% of the subjects had respiratory symptoms dominated by dyspnoea (43.1%) and cough (35%). 64.2% had abnormal spirometry. Chest X-ray analyses revealed pulmonary abnormalities among 32.9% of the subjects (of which 78.9% were small and 21.1% large opacities). The clinical and functional respiratory symptoms and the radiological abnormalities appeared early and their prevalence increased with the duration of the exposure to dust. There was no correlation between the outcome of lung function tests and chest X-rays opacities. Pit digging work appears highly silicogenic, and it is imperative to implement medical and technical prevention measures to reduce respiratory hazards.
