The QGIS project is a prominent open-source geographic information system (GIS) that has evolved over two decades, contributing significantly to the geospatial community. This paper presents the development, governance, and operational challenges faced by QGIS, providing an in-depth analysis of its growth from a hobby project to a global platform. We examine the project's organizational structure, release management, and infrastructure, alongside the financial model that sustains its development. The paper also addresses key challenges such as licensing complexities, group decision-making dynamics, and the balancing of innovation with stability in an open-source environment. Additionally, we highlight QGIS's broad applicability across industries and its continued success in fostering community-driven development.

Artisanal and small-scale gold mining (ASGM) in Burkina Faso increasingly relies on cyanide, intensifying concerns about environmental contamination and human exposure. This study assessed free cyanide levels in water and soil across three ASGM sites-Zougnazagmiline, Guido, and Galgouli. Water samples (surface and groundwater) and topsoil (0-20 cm) were analyzed using the pyridine-pyrazolone method.

The seasonal variations, spatial distribution, and health risk assessment of 13 volatile organic compounds (VOCs), particularly benzene, toluene, ethyl benzene, and xylene (BTEX), in the ambient air of Dilovası, a Turkish city with unplanned urbanization, are presented in this study. Using passive tube sampling, at 22 locations in Dilovası, air samples were collected separately for the summer and winter, and concentrations were measured using thermal desorption GC-MS. Pollution maps were created using the Golden Software Surfer program and QGIS Desktop 3.
