Mercury Exposure & Artisanal Gold Mining in Sub-Saharan Africa

Abstract

Synthetic dataset modelling mercury (Hg) exposure from artisanal and small-scale gold mining (ASGM), biomarker levels, neurological and renal health outcomes across three regional scenarios in SSA. ASGM is the largest anthropogenic source of mercury globally, accounting for 37% of 2,200 tonnes/year (UNEP 2018). Approximately 9 million ASGM workers in Africa are exposed, with extremely low PPE and retort use rates.

Scenarios

  • West Africa Alluvial: Ghana/Mali/Burkina Faso-type alluvial mining with moderate mercury use and high fish consumption pathways.
  • East Africa Hard-Rock: Tanzania/Kenya/Uganda-type hard-rock mining with higher exposure levels and gold shop processing.
  • Southern Africa High-Use: Zimbabwe/Mozambique-type operations with the highest mercury consumption per capita and poorest safety practices.

Validation

Validation Report

The 8-panel validation report shows: urine Hg distributions, neurological outcomes, biomarker elevation rates, urine Hg vs proteinuria dose-response, worker role distributions, safety practice adoption, kidney effects, and fish consumption/contamination patterns.

Usage

from datasets import load_dataset
ds = load_dataset("electricsheepafrica/mercury-asgm-exposure", "west_africa_alluvial")

Limitations

  • Synthetic data; not for clinical decision-making.
  • Biomarker levels modelled as log-normal; real distributions vary by site.
  • Does not capture chronic cumulative exposure or seasonal variation.
  • PPE/retort adoption rates are conservative estimates.
