Lead in soils of Mexico: content, spatial variation, availability for humans
Abstract
The distribution of lead in the soil cover of one of the largest cities in the world - Mexico. A comparative analysis of the content of this metal in soils of different parts of the city and its availability is determined for the human body. Found that lead levels in the city vary in the range of 125-1186 mg/kg, significantly higher than background concentrations. The largest number of elements recorded in the central and southern areas of the city, which is associated with the duration and intensity of traffic load. At the same time these areas are characterized by a high degree of bioavailability of the metal (60 to 100%).

The content of pollutants and eutrophicants in urban puddles
Abstract
A comparative research of a level of pollution of city puddles and runoff from urban areas was carried out. It is shown, that the formation of puddles should be considered as an important factor defining ways of migration of pollutants and eutrophicants in urbanized areas.

Modeling of a global biogeochemical cycle of carbon and nitrogen in system the atmosphere - plants - the soil
Abstract
Modeling of a global biogeochemical cycle of carbon and nitrogen against a background of global warming and other anthropogenous impacts of the biosphere have been carried out. Results of modeling revealed unsoundness of the theory of threshold crisis of the biosphere.

Problems of providing safe meals for students in educational institutions
Abstract
Main problems of organizing safe meal provision system in educational institutions are analyzed in the article. It is shown that safe nutrition not only determines quality of life, but also plays a major role in disease prevention and maintaining health among students. Based of experimental work carried out in school, structure of nutrition of students is analyzed, disturbances in nutritional status are identified, measures on working with students and parents are taken. A complex approach to organizing safe meal provision for students in educational institutions is proposed.

Interrelation of adaptation level and dynamics of study progress of the chinese students
Abstract
In work the empirical data of researches for some years, showing interrelation of adaptation processes of the Chinese students to ecology of a capital megacity with level of mastering of knowledge and study progress in an university is presented. It is shown that the given communication proves to be true the received results of the test on a self-appraisal of the functional condition and changes of a parity of uneasiness levels under the test of Spilberger-Hanin in the course of training.

Сesium-137 migration in non-flowing basins
Abstract
There is given the results of investigation of Cesium-137 migration in non-flowing basins. It is revealed and shown, that in the result of water self-purification cesium precipitates on the bottom of basin, on the surface of water plants and microorganisms, moves away with evaporated moisture. It is also given quantitative indexes of migration processes.
