Mercury contamination mind map
Context
Tropical birds in Central and South America
Signs of mercury contamination
Cause
Artisanal and small-scale gold mining
Proximity to mining
Within 7 km
Mercury use in Gold mining
Forms amalgam with gold
Extraction of gold from ore
Amalgamation process
Captures fine gold particles
Environmental and health concerns
Due to mercury pollution
Key Findings
Declining biodiversity
Tropical birds affected
Linked to
Neurological illness
Immune diseases
Reproductive failure
In humans and birds
Birds as indicators
Sensitive to ecosystem health
“Canary in the gold mine”
Signals environmental issues
