Abstract
Recent analyses of the muscle of several fish specimens
and the muscle, liver and fat of the Baikal seal show low levels
of heavy metals and organochlorine compounds.
Present and past observations suggest that despite land-based
sources of pollution, the general health status of the lake is good.
However, because of increasing local air pollution, the long-range
transport of pollutants emitted elsewhere and the expected increase
in pollutants reaching the lake via rivers, extremely careful control
measures in the hydrographic basin and continuous monitoring of
the lake water are essential. © 2000 Published by Elsevier
