The aim of this study was to assess carbon monoxide exposure and respiratory disorders in women at artisanal fish-smoking sites. Methods: This was a cross-sectional study of women fish smokers at two artisanal fish-smoking sites in Benin. Recruitment was exhaustive. An interview using a respiratory questionnaire inspired by the Union questionnaire, spirometry and carbon monoxide (CO) measurement were carried out. Descriptive analysis and comparison of means using Student’s t-test with a threshold of p = 0.05 were performed. Results: The median age of the 81 people surveyed was 40, with an interquartile range (IQT) of [25 to 75]. The median duration of daily exposure to smoke was 6 h IQT [4, 7]. Of those surveyed, 64 (79.01%) were illiterate and 39 (48.24%) had been working for 20 years. CO levels at the start of activity varied from 89 to 145 ppm in one case and from 40 to 89 ppm in the other. Respiratory symptoms were present in 19 (23.46%);18 (22.22%) had mild airway impairment on spirometry. There was a statistically significant decrease between the mean values of peak expiratory flow (PEF), mean expiratory volume in seconds (FEV1) and forced vital capacity (FVC) before and after exposure to smoke. Conclusion: CO levels are high on fish smoking sites and respiratory problems are common. Improved working conditions are important for these women.展开更多

The study was carried out from surveys on processing methods of fresh fish into smoked fish in the production areas. It took place from September 2009 to March 2012 on three smoking sites Port-Bou^t in the South of Abidjan, lie Boulay, Abobo-Doum6 and Koweit in the South-West of Abidjan and Abobo-Macaci in the North of Abidjan. The main risk factors which were identified in the formation of PAH, are the stakeholders, the smoking sites, the technologies, the handling and the storing. The black color and bitter taste of the fish were identified as sensory indicators of PAH formation in smoked fish.展开更多
