| Tartalmi kivonat: | This paper presents the spatial-temporal changes of the toxic element content in groundwater within urban area, Szeged (Hungary). In the course of our work groundwater contamination was monitored using twenty-eight sampling wells from the groundwater monitoring network of Szeged. The water samples were collected every month from October of 2010 and the nickel, lead, arsenic, cobalt, chrome, zinc, copper and cadmium concentrations were measured. We examined the relationship of this different pollutants and their distribution in the city. According to the results, the groundwater of Szeged is contaminated with lead, nickel, copper, zinc and arsenic, mainly in the downtown, close to the river Tisza. Statistical relationship, used Spearman’s rank correlation, was determined among the siderophile (namely chrome and nickel), and chalcophile elements (lead, zinc, cadmium, copper). The temporal changes are similar by the most components, and compared to the average monthly rainfall the concentrations follow the rainfall changes with one month delay. The poorest groundwater quality in the examined period was measured at the beginning of winter and early spring, the autumn months characterized the clearest water. |
