People in American Samoa are being warned not to eat any fish or shellfish from the Harbour, after a new study showed high levels of toxicity.
The American Samoa Environmental Protection Agency studied the level of toxicity in marine life within the territory's coastal reefs.
While the study showed coastal reefs do not appear to have significant levels of contaminants, the study has confirmed previous studies for the Harbour.
It indicates that high concentrations of arsenic and mercury are high enough to justify a general fish advisory for the area.
The study was done in conjunction with Hawaii's Department of Health.
