Background Geochemical conditions can have positive and negative impacts on human health. In Slovakia, for example, studies indicate that inhabitants of Krupina county are adversely affected by the neogen vulcanite rocks. These reduce the availability of key biogenic chemical elements such as Ca, Mg, Se, Al, Zn (all of which are needed for human health). The concentrations of these elements in Krupina's soils and groundwater are approximately half the level of other regions in Slovakia. A low level of these elements can lead to different health issues linked to, for instance, the endocrine glands or the cardiovascular system. Knowledge gaps exist in data for Krupina county concerning correlations between the composition of soil or water and health indicators. Such knowledge would help to inform appropriate preventive interventions or remediation measures for the county’s population. Objectives The main objective of the project is to improve of the health of residents of Krupina district. To do this it will confirm the links between health issues and geological conditions. Knowledge gathered by the project will be used to inform appropriate mitigation measures for reducing health risks from geological conditions. Specific project actions will include: Gathering of data for environmental indicators (chemical elements/components) concerning soils, groundwater and drinking water; Gathering of new data on health indicators (indicators of demographic changes and the health of the population); By linking these two datasets, the project will be able to assess the impact of the geological environment on the health of the resident population; The project team will analyse chemical contents of critical elements (e.g. Ca, Mg, Se, I, Ba, Zn and others) in various biological materials (blood, urine, hair, nail, milk-tooth) to confirm the relationship between the geological environment and the health of Krupina's residents; An evaluation of lifestyle factors and access to health care amongst Krupina's residents will be carried out; and Limit values will be defined for soils and drinking and groundwater (drinking and ground) as well as maximum acceptable levels and minimum levels necessary for human organisms. Through these actions, the project will design and implement measures for minimising negative influences of Krupina's geology. Implementation actions will focus mainly on education, training and legislative work. Special attention will be paid to identifying appropriate technological solutions. Expected results: The project expects to contribute to a general improvement of residents’ health status. Other outcomes should include: Clarification, compilation and monitoring of data concerning interrelated environmental and health indicators; Defining of limits of all environmental indicators based on their influence on human health as a background for legislative implementation in relevant guidelines; Proposal of measures aimed at reducing unfavourable impacts from the geological environment on human health; Environmental-health education for the people of Krupina; and Testing of the performance of technological measures (adding limestone and dolomite) on selected sources of groundwater used for drinking purposes; as well as other measures for improving water and soil quality in Krupina (namely increased levels of Ca and Mg) and thereby improving the health of its population.
