Chronic exposure to mercury can lead to neurological disorders, developmental delays, and other serious health issues. Many community members have experienced symptoms of mercury poisoning, leading to long-term health challenges.

Environmental Impact

The environmental impact of mercury contamination in Grassy Narrows has been devastating. The local ecosystem has been disrupted, with fish populations being significantly affected by mercury levels.
