This study is a contribution to the study of air pollution at Nakoyakpala neighborhood, Urban Commune of Nzerekore, Republic of Guinea. Its main objective is to analyze atmospheric fallout at Nakoyakpala neighborhood. To do this, four (04) atmospheric fallout measuring sites were identified in this neighborhood: S1 (Nakoyakpala Market Roundabout); S2 (Crossroads bordering the Mohomou, Gbangana and Nakoyakpala neighborhood very close to the welding workshop); S3 (Empty space facing the Parc des Princes nightclub) and S4 (University of NZerekore Courtyard). Atmospheric fallouts were measured over a 13-hour period for a 12-day period (from May 5 to May 16, 2025) at our various stations. The dust amount was 0.1350 g at S1, 0.1111 g at S2, 0.0961 g at S3 and 0.0451 g at S4, respectively. Thus, the total quantity of dust per hour in the Nakoyakpala neighborhood across the different sampling stations is 27.72 mg.m-2.h-1. It was also determined by day; it is 665.28 mg.m-2.day-1 over an area of 237 ha. This study on atmospheric fallout is the first in Guinea.
