Abstract

The paper presents the results of risk assessment of the area of the Zetor Company, on which the environmental burden of chromium occurs, resulting from the operation of a former electroplating plant. The concentration of chromium was determined by the method of inductively coupled plasma atomic emission spectrometry. We have calculated non-carcinogenic risks for workers provided that the premises are intended for industrial use and for children aged six years and younger and adults provided that the premises are used as a residential zone. We have considered as exposure scenarios accidental ingestion of soils and contamination from constructional elements, inhalation of air containing dust with an absorbed contaminant and accidental ingestion of groundwater. We have also evaluated a genotoxic risk resulting from inhalation of contaminated air by employees. Keywords: dermal contact, exposure, chromium, ingestion, inhalation, carcinogenic risk, nun-carcinogenic risk. 1 Introduction Contaminated soil, rock environment and groundwater pose a significant problem in environmental protection. In many cases, environmental burdens are a source of the unacceptable risk for the health of the population, groundwater and surface water, natural resources as well as other environmental components and often preclude the use of a site and the development of activities in a region. The need for high financial sums to remove environmental burdens and limited funds on the other hand require an integrated system of assessment and
