Metals in dolphin brains reveal hidden risks for ocean health

A single stranded dolphin's brain holds a warning we cannot ignore. Hepatic mercury doubled, and frontal cortex tau pathology rose by eight percentage points. This is not correlation alone, it is a measurable, empirical signal. Cetaceans live long, accumulate metals, and now show neuropathological markers that link contaminants to neurodegeneration. Validated risk assessment frameworks must integrate these findings. Understanding drives protection. From the Mediterranean to the global ocean, the evidence is calibrated and clear.
