Northern rivers turn orange and toxic due to thawing permafrost, study shows
A recent study reveals that thawing permafrost is causing northern rivers in Canada to turn orange and toxic. The exposure of ancient bedrock is releasing harmful metals, leading to contamination levels similar to those found in mining sites. This environmental change poses significant risks to the ecosystem and water quality in the region.
- ▪Thawing permafrost is exposing ancient bedrock in Canada.
- ▪Toxic metals released from the bedrock are contaminating northern rivers.
- ▪Some subarctic streams are now comparable to highly acidic mining sites.
