Knowledge and perceptions of health and environmental risks related to artisanal gold mining by the artisanal miners in Burkina Faso: a cross-sectional survey

Abstract

INTRODUCTION: artisanal gold mining is an activity ensuring the survival of about 700,000 families in Burkina Faso with a considerable contribution to the national economy. Techniques and chemicals used in the operation, have adverse impacts on health and the environment. Our study aims to evaluate the perceptions and knowledge of these different impacts among artisanal gold miners. METHODS: a cross-sectional survey was conducted in artisanal gold mines Bouda and Nagsene in the region of the North of Burkina Faso. Two hundred miners over 18 years of age were interviewed. RESULTS: all the participants have recognized that gold mining has health impacts and 88.5% felt these impacts as important with a significantly higher proportion among those with more than 3 years seniority (p = 0.001). The environmental impacts were perceived as important by 64.5% of miners, with a significant difference according to the position (p = 0.004). Sixty percent (60%) of respondents could identify at least 3 of the 5 health impacts of gold mining listed and 49.5% acknowledged at least 3 impacts on the environment. The diggers had significantly more knowledge about the symptoms (p = 0.001). CONCLUSION: study highlights the lack of knowledge of the Stampeders on the health and environmental impacts of artisanal gold mining. Findings might be used to develop more effective awareness campaigns in the future. Communication with diggers must focus on the risk perception because it appears that raising risk perceptions from low to high would have a major effect on behavior.
