Abstract
The groundwaters can be found around the world. Chromium is well-known element with confirmed toxic, carcinogenic and mutagenic properties, which can cause acute and chronic poisoning. Chromium is widely distributed in Earth’s crust. It can exist in valences from II to VI. In general, food appears to be the major source of intake. Chromium(III) is an essential nutrient (Sharma et al., 2012; Shahid et al., 2017). In aqueous environment the most abundant of chromium species are trivalent and hexavalent chromium compounds. The mobilization of this forms and their concentrations are various and dependant on the series of parameters i.e.: lithology of groundwater reservoir, pressure, temperature, pH value, redox potential, gasses presence (WHO, 2011; Witczak et al., 2013). For the purpose of this work the samples of groundwater from the public well located in Kraków (Poland) were collected. The water from this well is commonly used for drinking purpose by citizens of the city. Water collected to the different kind containers is not immediately drank by people, but stored in various (not always proper) conditions. Groundwater samples were collected to brand new containers made from polyethylene terephthalate in different colours (transparent, green, blue and brown) to check an influence of container type on a chromium concentration changes in water samples. The unstable parameters of water (temperature, pH, redox potential, electrical conductivity) were measured in on-line system to minimize the impact of environmental conditions on their values. Chemical analyses were conducted after samples delivery to the Hydrogeochemical Laboratory of the AGH University of Science and Technology. Both chemical analysis results and field measurements were used for the hydrogeochemical modelling performed with the PHREEQC programme. The results showed that independently on the parameters obtained from laboratory analyses and type of container used for sampling, the most abundant species of Cr are trivalent chromium compounds.
