[INDICES OF THE OXIDATIVE STATUS IN CHRONIC ADMINISTRATION OF COLLOID CARBONATE CALCIUM PRAPARATION WITH FAUCET AND LOW-MINERALIZED DRINKING WATER IN RATS].

There are discussed the changes of an array of indices of the oxidative status in chronic administration of colloidal calcium carbonate preparation with faucet and low-mineralized drinking water to rats. Slight differences between significant effects of administration of 3 and 30 mg/L of preparation permit to suggest that the process of its incoming delivery into organism of rats has a bottleneck in the nature of total capacity of macrophages of intestinal lymphoid tissue to absorption of particles.

[MONITORING OF THE CONTENT OF HEAVY METALS AND ELEMENTS IN THE SNOW COVER IN AGRICULTURAL SOILS AT THE TERRITORY OF THE MOSCOW REGION].

The monitoring of snow cover pollution by heavy metals and elements (zinc, copper, lead, cadmium, arsenic, nickel, chromium, strontium, manganese, fluorine, lithium) was performed in 20 districts of the Moscow region in 2009, 2012 and 2013. The assessment of the levels of contamination by heavy metals and elements was given by means of comparison of them with the average values in the snow cover near Moscow in the end of the last century and in some areas of the world, that no exposed to technological environmental impact. 7 districts of Moscow region were characterized by a high content of lead and cadmium in the snow water.

[Monitoring of the chemical composition of snow cover pollution in the Moscow region].

Monitoring of snow cover pollution as an indicator of ambient air pollution in 20 districts in the Moscow region during 2009-2013 was performed. The identification with a quantitative assessment of a wide array of organic compounds and the control of the main physical and chemical and inorganic indices of snow water pollution were carried out. More than 60 organic substances for most of which there are no the hygienic standards were established.

[Environment and health: priorities for preventive medicine].

Contemporary environmental factors influencing the formation of the environment and public health have been analyzed The increasing chemical pollution of the environment (air water, soil, living environment), and the intensification of the impact of physical factors in the first place, "electromagnetic smog" associated with the widespread use of appliances and computer equipment, cellular threaten public health have been shown. In this connection, there were determined priorities and main directions of research in the platform "Preventive Environment", approved by Ministry of Health of Russia, which is based on the concept of the factor prevention of noninfectious diseases.

[Headspace analysis of volatile organic compounds (VOC) in drinking water by the method of gas chromatography].

In the paper there is presented a methodology of analysis of headspace 52 volatile organic compounds in drinking water by the method of gas chromatography with the use of the chromatograph "Crystal 5000.2" with three detectors and automatic attachment Lab Hut 200N NT-200 for the preparation of the sample water and vapor phase input. The lower limit of detection for all compounds in the 2-10 times lower than that of the corresponding standard value.
