Abstract
Currently, the most popular are the express methods of quality control of the environment, which permit a relatively rapid assessment of ecological and geochemical situation. one such method is based on the use snow cover. snow has a high sorption capacity and is informative in identifying the object of man-made pollution of the urban environment. the paper presents the results of a study of the chemical composition of snow that had fallen in Voronezh during winter 2015. snow samples were taken in the period prior to snowmelt in various functional areas of the city. in order to identify the degree of technogenic impact on the various parts of the city of Voronezh, was made a comparative analysis of the results:аccording to the actual presence of pollutants in precipitation for the study of functional areas;сalculate the rate on the concentration of chemical elements for test samples of snow.according to the degree of mineralization and dust content in snow can be seen technogenic pressure on environment.therefore, a comparative analysis of the degree of contamination of snow in the various functional areas of the city were carried out for the two indicators of the chemical composition - the total mineralization and suspended particles(dust).the results of the analysis of the chemical composition of the melt water indicate an increased level of technogenic pollution of snow cover in all investigated functional areas of Voronezh.
Highlights
The article presents the results of a study of the element status of residents of different ethnic groups (Koryak, Even, mestizo) Magadan region
It is suggested that this phenomenon is caused by adaptation to the conditions of the indigenous population of the North
The higher silicon content in the hair of Aboriginal and Métis is consistent with the data that the Magadan region is silicic province
Summary
The article presents the results of a study of the element status of residents of different ethnic groups (Koryak, Even, mestizo) Magadan region. - по рассчитанным коэффициентам концентрации химических элементов для исследуемых проб снега. Для более объективной характеристики геохимической индикации загрязнения снежного покрова за основу принимается сопоставление концентраций поллютантов городских проб снега с соответствующими значениями их фонового аналога.
