Abstract

The degree of soil pollutants in the Dunaújváros area has been monitored regularly at 10 sampling points of the town from the upper 0–20 cm and lower 20–40 cm layers of the soils. The quantity of some organic (PAH, TPH) and inorganic (toxic metal) pollutants were determined by GC-MS and ICP analyzation. Microbial status, such as the total cultivable bacteria (CFU) and total catabolic enzyme activity, measured by fluorescein diacetate analysis (FDA) were also estimated. The area of the industrial town could be divided into more and less contaminated regions, although the measured pollutants were far below the estimated permissible limits. However, at some of the more polluted soils even triple amounts of contaminants could be measured compared to the lesscontaminated sites. Among inorganics the Zn microelement reached the highest levels (average is about 100 mg·kg−1 soil), which could be related to the heavy industrial activity. A positive correlation appeared among the organic and inorganic pollutants and also between the pollutants and the measured enzymatic values. The enhanced FDA activity was found at the most contaminated sites preceding the potential “loss of function” on a long-term basis. The fast and reliable microbial parameter could be suggested as further regular monitoring tool.
