Trace Elements in Lake Baikal:Current Status,Forecast and Monitoring Problems
in natural(“preindustrial)chemical content in basic abiotic and biological compartments of the Lake geosystem.This approach was used to evaluate background “base-line levels of 6 major and about 50 minor and trace elements in the Lake Baikal water body using a number of most reliable data reported within 1992-2012.In terms of environment geochemistry Baikal is one of the purest water reservoirs on the Earth.A simple mass balance model was proposed for assessing possible anthropogenic impact on Baikal water geochemistry.Estimations of change trends showed that only for Na+,24 SO ?,Cl? and Mo growth rate of their average concentrations in the Lake occurred to be 1%,3%,7%and 2%in every 10 years.Space-time monitoring schedules for all water body compartments of the Lake are proposed as well as similar monitoring programs for tributaries,precipitations,bottom sediments,aquatic biota.
