Findings from a study describing the arsenic legacy left in lake-bottom sediments near an abandoned Halifax gold mine are setting off alarm bells for a senior cancer researcher.
A paper published Monday in the journal Science of the Total Environment says a dated core sample taken from the bottom of Lake Charles discovered arsenic at 4,960 milligrams per kilogram, more than 280 times higher than levels where biological harm is expected.

Arsenic Legacy in Lake Bottom Sediments From Historic N.S. Mine Worries Researcher
HALIFAX Findings from a study describing the arsenic legacy left in lake−bottom sediments near an abandoned Halifax gold mine are setting off alarm bells for a senior cancer researcher.
A paper published Monday in the journal Science of the Total Environment says a dated core sample taken from the bottom of Lake Charles discovered arsenic at 4,960 milligrams per kilogram, more than 280 times higher than levels “where biological harm is expected.”
The site is downstream from the historic Montague mines, where successive gold rushes saw the creation of 121,000 tonnes of arsenic-rich tailings between the 1860s and 1940.
