description: Title: Supplementary Materials, Datasets, and Reproducible Code for: Arsenic Exposure in Abandoned Gold Mining Communities: Health Risk Assessment–Driven Machine Learning Risk Mapping in Loei, Thailand

Description: This repository contains the comprehensive supplementary materials, raw datasets, ethical documentation, and reproducible code workflows associated with the research article "Arsenic Exposure in Abandoned Gold Mining Communities: Health Risk Assessment–Driven Machine Learning Risk Mapping in Loei, Thailand", submitted to the International Journal of Environmental Research.

The study integrates quantitative Human Health Risk Assessment (HHRA) with Extreme Gradient Boosting (XGBoost) machine learning to evaluate arsenic exposure pathways across seven villages surrounding the abandoned Tungkum Ltd. gold mine in Loei Province, Thailand.
