Plants, the leading fixed way of life, are forced to be particularly plastic on environmental impact responses of the environment. The most important external factors include the light, which is not only a source of energy for photosynthesis, but also a signal, activating and changing the program of development of the plant. Objective: To study the content and ratio of different forms of photosynthetic pigments in leaves of plants that grow only in natural light (forest) and compared to individuals present in the conditions of an additional light (located near the street lamps and lighted windows of houses). The experience included birch specimens of plants growing in a forest tract Gutorevo (dense stands of birch within the pine forest) and tree planting ordinary Lear Park (southern suburbs of Kursk area). The leaves are weighed. pigment content was determined by in vitro analysis in four replicates. The content of chlorophylls and carotenoids were determined by calculation. Volume fraction pigments evaluated. Statistical analysis were Student t-criterion. The content of chlorophyll and carotenoid in the leaves of birch in an artificial increase in the duration of the light period in the temperate climate of the Kursk region. In plants, an increase of chlorophyll content (a + b) 12.0% of carotenoids in the leaves 23.0%. There is reason to believe that the adaptation of the pigment apparatus birch plants growing under natural light (forest) and located in the area of artificial lighting is done by transforming the light-harvesting complex. Factor complex urban environment, including sunlight, soil compaction podkronovogo space in which increasingly suffering park biome, does not reduce the content of pigments in the end of the growing season, in comparison with individuals forest biome. This testifies to their high stability and better adaptation to the effects of natural and anthropogenic factors.

Differences in the processes of seasonal changes in bioluminescence intensity in relatively open waters of the sea on the south-western shelf of the Crimea and in the waters of the Sevastopol Bay (the Black Sea) are shown. The influence of hydrological seasons temperature conditions on the pattern of light intensity changes of hydrobionts within a year. The correlation coefficients of interannual changes in bioluminescence intensity during the different seasonal temperature for deep water area of the sea and shallow waret bay of Sevastopol calculated. The important role of the thermohaline structure of waters in the seasonal variability of the bioluminescence intensity found.

On the basis of the spatial mathematical model of the global carbon dioxide cycle in the biosphere the absorption of carbon dioxide emissions from the fossil fuel burning, deforestation, and soil erosion by terrestrial ecosystems was calculated for all the world and countries of the Central and South America. Effects of deforestation of tropical forests and soil erosion because of inappropriate land use and climate change were calculated until 2060 for countries of the Central and South America.

Hemostatic system - this is an important mechanism for maintaining hemostasis. At the same time, particularly hemostatic system in healthy active lactating cows with mastitis beginning are not completely clarified. The goal - to find out the level of functional activity of hemostasis in cows in mid-lactation in norm and in conditions of incipient mastitis. Investigations were carried out on 61 cow calving 3-4 contained in the conditions of the Samara region. Of these, the control group consisted of 24 healthy cows and 37 cows with signs of incipient mastitis amounted experimental group. The paper applied hematologic and statistical methods. Based on literature data, it is clear that breastfeeding affects the intensity of the hemostatic process. The paper found that in mid-lactation cows healthy there is a weakening of activating effects in hemostasis and increased fibrinolysis mechanisms. This leads to the maintenance of their optimum rheological properties of blood, ensuring delivery of the required amount of nutrients and oxygen to all the organs and tissues, promoting the rise of milk production. In the case of inflammation of the mammary gland in cows come changes in the hemostatic system activities that form the propensity to thrombosis. Developing their hemostatic activation is associated with simultaneous strengthening of its plasma and platelet units. It becomes clear that in lactating cows in the early development of the terms of mastitis occurs strengthen hemostatic mechanisms.

Performance test-objects for biotesting toxic soils, contaminated waste leather and cement productive activities, remediation of the substrates are vermicomposting: worms (Lumbricina) - low-temperature stability, weight and adaptive descriptions, the reproducibility and recovery of populations, number of specimens, cocoons, juveniles; for plants: Triticum aestivum L. - growth parameters, Lactuca sativa- is the water-holding capacity, water content of grain leaves.

High absorption ability of water plants makes them ideal test objects for quantitative and qualitative determination of anthropogenic chemical loads to the pond.In modelling the radioecological processes of great importance are the methods of logical descriptions, which use, if you cannot find a mathematically precise dependencies. In the case of radioactive contamination of ecosystems, gathering necessary for the calculation of the model data to predict the situation.

This article analyses challenges of the fire extinguishing process at fuel storage facilities and looks at modern technologies aimed at extinguishing burning petrochemicals, such as: subsurface foam injection, combined gas and powder fire extinguishing technology «BiZone», aerosol generator «Purga», automatic fire-fighting system USP-01F, foam generating substance «Storm», heat shields «Sogda» designed to protect firefighters from thermal radiation, etc. Recommendations are given to facilitate the use of advanced fire suppression technologies at fuel storage facilities.

The research investigates the influence of natural and environmental factors on the prospects of introduction of green building technology in Russia. The classification and comparative analysis of green building technologies are based on the experience used in Russian and international practice. The author identified several geographic factors and explained their influence on the introduction of green building technologies at different regional levels. Specifics of of the natural and environmental factors inventory in regard to combination of suitable green building technologies are shown in the example of a model city.

This paper presents the evaluation of the use of insecticides in the agricultural production of the Kursk region. Studied territorial load dominant crop insecticides in a complex region for the period 2006-2013, were ranked the region in terms of territorial load insecticides. Estimated figures on theenvironmental risk of the formation of the pathology of the gastrointestinal tract of the adult population of the Kursk region in the intensive use of insecticides. Environmentally sensitive identified pathologies such as gastric ulcer and duodenal ulcers, gastritis and duodenitis, functional bowel disorders, diseases of the pancreas.
