Researchers have developed an unsupervised machine learning framework to identify heavy metal contamination in soils, focusing on urbanizing regions in Ghana. The study analyzed eight metals and health risk indices across twelve waste sites, successfully pinpointing anomalous samples using methods like Isolation Forest and PCA reconstruction error. These anomalies, concentrated at a single site, showed significantly higher health risk values, demonstrating the framework's ability to provide targeted insights for environmental management. AI
