Green Hands: Causes from Copper, Chemicals, Infections, and Medical Conditions

Possible Causes

  • Copper Toxicity: Occupational exposure or Wilson’s disease (copper accumulation).
  • Pesticide/Herbicide Contact: Direct skin exposure or contaminated food/water.
  • Pseudomonas Infection: Produces green pigment (pyocyanin).
  • Argyria: Silver deposition → blue‑gray/green skin.
  • Hemochromatosis: Iron overload → bronze/green discoloration.
  • Corroded Copper Pipes: Copper leaches into water; green staining on hands.
  • Hand Sanitizer: Some formulations cause temporary green tint.
