Scientific foundations and principles of estimation and prediction of environmental safety in urbanized territories of the Republic of Tatarstan

At present, the actual scientific direction is the establishment of regular causal relationships in a complex system: the technospheric environment (soil) - the plant - the agricultural animal (the bird) - the person. The determination of the mechanisms for the development of the results and effects of the action of different values of environmental factors on different groups of living organisms and the population are the basis for obtaining data for environmental monitoring. Ecological monitoring of the habitat is aimed at using biotesting of plants and animals to identify the morphophysiological features and sensitivity of living organisms and further the children’s organism and the elderly to various environmental factors. All these studies should provide information for the conservation of plant and animal biodiversity in urbanized areas in the Republic of Tatarstan.
