This article assesses the impact of industrial noise emitted by the Sangarédi bauxite mine, operated by the Compagnie des Bauxites de Guinée (CBG), on local communities. Noise levels measured in this area frequently exceed the accepted norms, with 69.56% of recorded readings exceeding the critical limit of 115 dB. Moreover, nine measurements even exceeded 120 dB between May 1 and July 24, 2023, indicating significant noise exposure for residents. Daytime noise levels regularly exceed the 55 dB standard, while night-time levels are generally within the prescribed limits. Analysis of the noise generated by ore trains passing through the surrounding villages shows that, of the nine values measured, five (55.55%) are below permissible levels. However, despite some compliant measures, the high noise levels recorded continue to cause significant adverse health impacts for local residents. These impacts include stress, hearing problems and other serious health complications, demonstrating the urgent need for effective noise abatement measures to protect the health and well-being of local communities. The results reinforce the importance of continuous monitoring and rapid intervention to mitigate these noise nuisances and improve the quality of life of the populations affected.

The present study presents the petrographic and geochemical characteristics (major elements) of granitoids and metasediments of the Ferke belt in northern Cote d’Ivoire. The petrographic study reveals a variety of granitoids such as: tonalite, granodiorites and granites and adamellite. Metasediments consists of wacke, shale and Fe Sand. Chemical analysis indicates that these granitoids come from volcanic arc. The geodynamic context is subduction.
