Current knowledge points out a necessity for complex approach to a solution to contamination by heavy metals and undesirable elements. Potential risk areas can be found in the vicinity of tectonic faults and first of all industrial establishments (verified and supposed). Adverse heavy metals (e. g. beryllium) cause an increase in the incidence of malignant tumors (e. g. lung cancer). Among the most contaminated areas of the Slovak Republic is the Ziar basin's territory. Since 1990, the localities under investigation in this territory have shown a higher sickness rate (tumor diseases), compared to the national average. The work reports on a study of the relationship between beryllium content of soil and infant morbidity rate according to ICD-10. Since high beryllium concentrations were measured in the soils of the Ziar basin's territory (maximum beryllium concentration is 1.57 mg per kg), there is a potential risk to public health there, especially in the areas of the Hron River and its adjacent inflows. From statistical processing of pedological and health data it follows that there is a very highly positive relationship between beryllium and infant morbidity. Heavy metal contamination corresponds to loading the environment of the whole area.
