TOMSK, Dec 9 – RIA Tomsk. The student of Tomsk Polytechnic University Albyna Yalaltdinova together with colleagues from University of Technology of Troyes developed a universal technique by definition of the environment’s state according to structure of poplar leaves, and has already tested the technique in Ust Kamenogorsk (Kazakhstan), the press service of the HEI reports.
"According to the graduate student, the developed technique allows to estimate the level of pollution of the environment on a complex of chemical elements in leaves of a poplar. On the basis of the obtained data it is possible to draw conclusions on a certain impact of the environment on human health, living in this district", – it is told in the message.
The experts noted importance of the developed technique for world practice of ecological researches. There is a complex of large industrial enterprises including production of zinc, lead, and fuel for the NPP in Ust Kamenogorsk where work was carried out.
"University of Technology of Troyes was engaged in a risk assessment by manufacture of a certain type of production. Thus they used the generalized results from available databases for calculations. We developed the technique which allowed to estimate, firstly, influence of a complex of industrial enterprises, and, secondly, to use real results of geochemical researches", – the young scientist was quoted in the message.
Yalaltdinova explained that the scientists united two known techniques. The first – geochemical – is used in geology for studying of a chemical composition of plants, for example, in search of fields. "We determined the content of chemical elements by the tool neutron and activation analysis: selected leaves, dried them up, prepared for the analysis and defined. It is possible to determine to 28 elements with such method", – she told.
The second method – estimate of toxicity of certain elements for territories – is used abroad. "We used our data on a chemical composition of leaves in the technique which estimates risk for the population", – the graduate student noted.
As a result, the researches confirmed that the industrial enterprises make noticeable adverse effect on ecology of Ust Kamenogorsk and threaten health of citizens. According to the research supervisor, professor of department of geoecology and geochemistry of TPU Natalya Baranovskaya, scientists of Polytechnic University plan to expand geography and possibilities of use of the method, to adapt it for different environments.
"Together with the French colleagues the developed technique will be tested soon in three territories: in Tomsk, Paris and Troyes. It will allow not only to estimate pollution, but also to give an assessment of risks for health of the population", – it was emphasized in TPU.
