This paper presents the results of analyzes of water samples taken from individual water wells intended for supplying households in non-urbanized areas with low population and infrastructure density. Relatively high concentrations of harmful pollutants were found in ground waters of the examined spots located in the suburban areas which may increase the risk of health incidents in exposed populations. Based on long-term measurements carried out in individual spots and toxicological data, the individual health risks related to carcinogenic effects in humans were assessed, resulting from direct ingestion of such water and from dermal contact. Non-carcinogenic hazard levels were determined, as well. In this work a novel approach to health risk assessment was proposed. It consists of determining the risks that range between minimum and possible maximum values. In the case of limited traceability of a pollutant the maximum and minimum risk values were derived from the limit of quantification (LOQ). Thus, for the minimum risk, zero concentration was applied, while for calculation of the maximum risk, LOQ was used as the possible highest pollutant content in water. The calculations proved that using untreated water for consumption and bathing is likely to cause an increase of both mutagenic and toxic risk in humans concerned. Depending on the site, the calculated non-carcinogenic hazard level expressed by the hazard index HI ranges between 0.6 and 3.6 while the excess lifetime cancer risk ELCR is of the order of 10(-4).

Project assumptions

The overall goal of the project is to develop an innovative multifactor mathematical model enabling monitoring of bath contamination used in the electropolishing process of austenitic stainless steels. This model will allow optimization and reduction of process costs and will have an impact on reducing environmental pollution during electrolytic polishing of austenitic stainless steels.

The final outcome of the project will consist in the development of a method of monitoring the gradual contamination of the electropolishing bath.


The team deals with research in the field of electrochemistry, wastewater treatment, monitoring and optimization of processes in laboratory and industrial conditions. The diverse experience of individual members of the IonsMonit team is its strength.



Project: “A pioneering model for monitoring pollution of electropolishing process baths (IonsMonit)” financed by the National Center for Research and Development as part of the Lider programme.
