Human interaction with the environment has gone through several stages of evolution. Being a product of the natural evolution of living organisms in the biosphere, Homo sapiens as a species has evolved in the geochemical conditions of the virgin biosphere. The rapid development of intellectual abilities of this genus allowed, first, to survive in adverse environmental conditions around the whole world, then, to cultivate the land, transform the entire system of biocenoses, and now to create a new habitat for man exclusively. The result was a significant geochemical transformation of the virgin biosphere, but a kind of punishment for the achieved progress was the emergence of a number of endemic diseases of a geochemical nature. Nowadays a variety of anthropogenic sources of pollution and their location in various natural geochemical conditions require not only constant monitoring of the chemical state of soil, water, air and food products, but also the development of spatially differentiated approaches to assessing the risk of provoked diseases. To solve this problem it is necessary concertedly interpreting a geochemical and medical information in order to assess the risks to human health associated with modern natural and anthropogenic geochemical features in urban and rural habitats. During session we propose to discuss:
1) global trends of health transformation in new geochemical environment of modern noosphere;
2) criteria for determining pollution level depending on environmental and geochemical constrains;
3) new approaches to assess the risk of diseases of geochemical nature in different countries;
4) the problem of mapping the risk zones, related to negative medical effects due to deficiency or excess of certain chemical elements or compounds.
Session co-sponsored by the European Association of Geochemistry.
Human interaction with the environment has gone through several stages of evolution. Man as a species first survived in adverse environmental conditions around the world, then he began to cultivate the land, exploit other species and develop industry, changing the structure and composition of natural ecosystems, and now creates a new habitat exclusively in accordance with his own requirements. This activity leads to significant chemical pollution of the environment at the local, and in some cases at the regional level, which leads to disruption of natural food chains. This process is followed by the negative biological reactions of living organisms, including the man himself. These reactions and, in particular, endemic diseases of a geochemical nature can be regarded as a kind of punishment for the progress made. Emerging environmental problems require not only constant monitoring of the chemical state of soil, water, air and food products and identification of anthropogenic induced negative reactions, but also the development of spatially differentiated approaches to assessing the risk of triggered negative reactions and diseases. During our session, we will discuss:
1) global trends in health status in the new geochemical environment of the modern noosphere (the anthropogenic stage of biosphere evolution);
2) methods and criteria for determining the level of environmental pollution by metals, pesticides, radionuclides and pharmaceutical substances;
3) new approaches to assessing the risk of pollution and diseases of a geochemical nature in different countries;
4) the problems of identifying and mapping risk zones.
We kindly invite all interested parties to our session.
