Universal quantitative evaluation and standard-setting method of complex (multifactor)
impacts on fresh-waters ecosystems is developed and approbated. The suggested method uses the
revealed general laws of the best hydroecosystem bioindicator reaction - macrozoobenthocoenoses to multicomponent external impact, which is estimated by the original isobolic index. The present
techniques and data are based on representative long-term hydroecological research results executed
by the group of authors.
The approbation of this method is realized by the example of complex technogenic mining
enterprises impacts on especially vulnerable highest valued fish-economic river ecosystems. They
are the Luga River (under the Limited Liability Company "Industrial Group "Phosphorite" impact),
the Plussa River (the Joint-stock Companies "Leningradslanets", "Tsesla", "Shale processing plant"
and other), the Syas River (the Joint-stock Company "Boksitogorsky alumina" and "pikalevsky
alumina") and its inflows. In these situations technogenic eutrophication of river is burdened by
active reaction changes and complex (multifactor) contamination. The isobolic method use allowed:
to set the maximum permissible levels of these combination impacts on biota considering real factor
interactions; to realize adequate quantitative impact evaluation as the rate of excess by these
impacts of its maximum permissible level; to analyze environmental risk and predict most probable
technogenic damage; to develop quite effective environmental protection measures planning
quantitatively its results.
The theoretical basis and detailed description of the method are presented in collective
monograph "The isobolic method of multifactor anthropogenic impact on fresh-water ecosystems
evaluation and standard-setting by macrozoobenthos state " (СПб.: IAEMNPS, 2004, 304 p.; № of
state registration 05-12240). Practical applications of this method are illustrated in detail by the
factual data. Particular examples of the method used for solving various environmental protection
problems are also considered.
