Abstract

Breathing clean air is crucial for maintaining good human health. The air we inhale can significantly impact our physical and mental well-being, influenced by parameters such as particulate matter and gases (e.g. carbon dioxide, carbon monoxide, and nitrogen dioxide). Building on previous research that explored the effects of particulate matter (PM) in specific environments, analyzed using biometric indicators and machine learning models; this work focuses on the effects and estimation of inhale [...]

Abstract

Bacteriological contamination of water sources, often due to improper handling of human waste, poses significant public health risks. This study investigates coliform bacteria contamination in water sources across the Fako Division of Cameroon. Twenty water samples were collected from various sources, including streams, community water, springs, boreholes, and wells, and analyzed for total coliforms using Violet-Red-Bile-Lactose (VRBL) Agar. Additionally, 352 household questionnaires [...]
