Monitoring mercury effects on terrestrial and
aquatic wildlife in TCN resource area .
Monitoring Advisory Committee
As per the provisions of the Adverse Effects Agreement
with Manitoba Hydro Tataskweyak Cree Nation
will take responsibility for the management, implementation
and operation of their own community’s Offsetting Programs.
Ongoing evaluation of the success of offsetting programs,
based on their intended purpose, will take place at the community
level throughout Project implementation.
TCN will develop it's own approach to evaluate the effectiveness
of their offsetting programs and, based on their own values and priorities,
will measure whether the program(s)
continue to address their concerns about Keeyask Project-related effects.
Mercury is a metal naturally found in small amounts
in rocks soil.
Human activities such as the flooding of forested lands
that have peat moss soils, high in organic content
or the flooding of wetlands,
commonly result in a temporary increase in mercury
(in the form of methylmercury) in the water, and
subsequently in the organisms that live and use
Mercury reaches people most often through eating fish.
Health effects of mercury depend on the duration and the
quantity of the exposure
Fish such as Pickeral and Jackfish, that eat other fish
have higher amounts of mercury.
From Plankton To People
Mercury concentrations increase from one level
of the food chain to the next.
Women and children need to be particulary
careful when eating certain fish. Mercury in fish
is transfered through the blood to the growing baby,
resulting in developmental problems.
