Mercury Poisoning Haunts Colombian Amazon Communities

The Colombian Amazon is facing a silent crisis due to mercury pollution from gold mining. Mercury binds tightly to gold, allowing miners to extract it from crushed rock and dirt. However, this process releases toxic mercury into the environment.

Rainforest communities rely heavily on fishing for food, but many fish species contain high levels of mercury. Studies have shown that carnivorous fish tend to accumulate higher levels of mercury than non-predatory species.

According to a study by the University of Cartagena, 93% of hair samples from communities along the Apaporis River contained mercury levels above the World Health Organization's 'threshold.' Moreover, 86% had levels twice as high.
