The action of moderate Pb 2+ concentrations on the physiologo-biochemical values of the 1 st true leaves of wheat (Triticum aestivum L.) seedlings using markers of general use was explored. Stress changes at Pb 2+ concentrations from 0,03 mg/l were showed, the switching of the stress phases was demonstrated. Observed processes are discussing concerning with advisability of approaches for further researches of the lead-induced biological stress.

During the ontogeny of the animal undergoes successive, interlinked morphological, biochemical, and functional changes, which begin with the formation of zygote and occur throughout his life. Knowing the age rule is of great importance for the analysis of experimental data, assessing the implications of shifts, their interpretation and comparison with the biological norm-relevant values of physiological, biochemical, hematological, immunological parameters of blood, allowing you to judge the nature and extent of changes in the body. Knowing the age dynamics of functional and biochemical indices of blood in the ontogenesis of cattle is an important basis of rearing and maintaining the health of dairy cows.

There are given the measurement results of polychlorinated biphenyls concentration in the soils at a different functional areas of Yasenevo district in Moscow. Found that the major source of PCB in the district’s soils today are motorways.

The analysis of weather data for the period of the Caspian lowlands 1961—2010 years, index changes Hf and CL, vegetation productivity.

The morbidity rate analysis of thyroid pathology of the population of Bryansk region depending on anthropotechnogenic environmental pollution is carried out. It is revealed statistically significant (a = 0,05) higher level of morbidity rate of the population at the territories with combined radiation-chemical environment pollution.

In work it is presented empirical researches of a condition of cardiovascular system and level of a resistance to stress of first year students of different faculties (ecologists, engineers, philologists) and specialties in the period of examinations. Research selection made 122 students. Researches were conducted during the intersession period and during examinations. Research showed that during the intersession period at small stressful influences at the majority of examinees indicators of function dynamics are in limits of standard sizes and testify to sufficient functionality of an organism. Dependence between level of personal uneasiness of students and nature of their reactivity on an examination stress is revealed. During this period adaptation potential shows tension of mechanisms of adaptation in a stressful situation at first-year students with high level of personal uneasiness and adequate level of students’ adaptation process with average and low personal uneasiness.

The influence on the properties of erythrocytes microrheology regular athletic training at the first mature age persons with abdominal obesity 1 degree. Evaluated lipid peroxidation and antioxidant protection of plasma cytoarchitectonics and aggregation of red blood cells. With a view to the correction of all the patients have regular visits to the Athletics section 3 times a week for 1.5 hours. Score the variables included in those with abdominal obesity was conducted after 0.5 years, 1 year, 1.5 years and 2 years of study in the section. Drug therapy in any case. Statistical analysis of Student's test was conducted. After a year of regular training in athletics section patients achieved normalization of body weight, plasma lipid peroxidation, and cytoarchitectonics aggregation activity of red blood cells. Continued regular athletic training perpetuated achieved results.

This article highlights perspectives on developing communicative competence of future ecologists in the post-industrial era. Using an interdisciplinary approach, the authors suggest new ways of exploring professional communication and acquiring professional communication skills while learning a foreign language.
