Article is devoted to dynamics of Daphnia sensitivity to the of Ob basin small rivers waters. Considered materials from 2009 to 2012. Elykovo and Tura rivers were selected as of the objects. Bodies of Water are geographically distant and directly unrelated. Both rivers belong to the basin of the Ob River and are under various degrees and types of human impact. Among the types of impact taken of the oil-producing organizations, the impact of the city, located on the banks one of the rivers, etc. During the many years of monitoring research was conducted chemical analysis of water samples from the relevant sites. Noted the influence of individual elements and compounds on the physiological parameters Daphnia magna. We determined Daphnia the survival rates and fecundity. Noted a sensitivity analysis was conducted on the basis of parameters of the correlation coefficients. The regularity of the dynamics of the sensitivity of the predominant human intervention. A comparison of the sensitivity of the individual indicators. Established areas with the greatest degree of anthropogenic impact.
