Canada: Mercury poisoning in Ontario

Mercury Poisoning in First Nations Groups in Ontario, Canada 35 years of Minamata Disease in Canada

In 1969, it was revealed that a river system in Ontario, Canada had been contaminated with mercury emitted by a caustic soda factory located upstream. The residents in the 2 Indigenous communities along the river near Kenora, Ontario were poisoned by eating fish contaminated with mercury. In 1975, we proved that the mercury pollution was affecting the residents’ health through our clinical rese...

[Mercury poisoning].

Certain heavy metals such as mercury, lead, arsenic and cadmium are toxic even in reduced concentrations in blood. Their accumulation in the body causes serious illnesses. The most important heavy metals in human pathology are: mercury (Hg), cadmium (Cd), arsenic (As) and lead (Pb). The author mentions the heavy metal sources of poisoning, their toxicokinetics and toxicodynamics, clinical featu...

Quantitative assessment of upstream source influences on total gaseous mercury observations in Ontario, Canada

Hourly total gaseous mercury (TGM) concentrations at three monitoring sites (receptors) in Ontario were predicted for four selected periods at different seasons in 2002 using the Stochastic Time-Inverted Lagrangian Transport (STILT) model, which transports Lagrangian air parcels backward in time from the receptors to provide linkages to the source region in the upwind area. The STILT model was ...

Mercury in lake sediments of the Precambrian Shield near Huntsville, Ontario, Canada

W.W. Shilts Illinois State Geological Survey, 615 East Peabody Drive, Champaign, Illinois 61802, U.S.A. Abstract Long sediment cores (11 m) were collected from eight Precambrian Shield lakes in southern Ontario, Canada and analyzed for mercury (Hg), loss-on-ignition (LOI), and a suite of 36 other elements. Results indicated at least 100-fold variation in sediment Hg concentrations between lakes...
