Ignatyuk O. The dependence of productive-energy parameters of biosystems on the level of environment pollution by heavy metals

The dissertation is devoted to study of the qualitative and quantitative correlation between the level of an environment pollution by lead and nicel ions and productive indeces of the laboratory population of the Higher Plants and Fishes. The new results have been obtained on a change of intensity and efficiency of a bioproductive process in the toxic sphere. The oligodynamic oppression of the productive-energy indeces in the studied plants and animals results from the increase of a toxicant concentration. The most sensible productive-energy indeces have been established. The possibility of use of the above indeces for the estimation of the aquatic sphere quality by the function of biosystems response has been proved.
