Abstract

A human health is influenced by complex interaction of different factors. Impact of the geological environment is still scarcely acknowledged. Four groups of geofactors are analysed in the country scale (1) gravity and magnetic fields, (2) concentration of geochemical elements in the soil, (3) tectonics and soil lithology, (4) landscape (relief, woods, drainage network, wetlands). These groups do not encompass whole spectra of geofactors that may have an influence on the human health, but are recognised as possibly being of primary importance. The medical and human behaviour parameters list the schizophrenia, suicides, homicides, alcoholic psychosis, drug addicts, crimes. As far the study considers very different parameters involved, a statistical method was applied that ensures objective identification of existing relationships. The different data formats were unified using GIS techniques that allowed scaling of geological databases to 45 administrative regions.
Schizophrenia is shown to positively correlate with the magnetic field, in other words, the higher is magnetic field the higher is a disease risk. By contrast, the gravity field intensity correlates negatively with the crime distribution. The tectonic zones recognised in the potential fields maps seems to have some influence on the homicide distribution. The landscape has only a minor influence. The differentiation of the relief (hilly areas) statistically increases the alcoholic psychosis. Some geochemical elements contained in the soil have statistically strong correlations with some diseases and human behaviour. Schizophrenia and suicides are “remedied” by P-, Pb-, Sn-, Y-, Yb-reach environments. It is notable that only one medical parameters of six analysed, i.e. drug addicts, do not show any statistical correlation with geological factors, whereas the others indicate clears relationship to particular geofactors.
Different geological processes are very closely interrelated, such as different types of the earth’s crust heaving different characteristics of the potential fields significantly influences processes accounted for formation of the present landscape and (sub)soil lithologies, as well as geochemical elements often reflect particular lithological groups typical for particular geological conditions. Still, obtained strong statistical correlations undoubtedly point to significant role of geofactors as regards human health.
