Trace elements in Phragmites australis growing in constructed wetlands for treatment of municipal wastewater.

Popis výsledku v původním jazyce

Biomass of Phragmites australis growing in four constructed wetlands with horizontal subsurface flow (HF CWs) in the Czech Republic have been analyzed for 19 trace elements. Concentrations of monitored elements in both aboveground and belowground plant tissues were similar to those found in plants growing in natural stands. The highest concentrations were recorded for Al, Fe, Mn, Ba and Zn while the lowest concentrations were those of Hg, U and Cd. Concentrations decreased in the order of roots > rhizomes > leaves > stems. The root/leaf ratio averaged 70 and varied between 1.4 for molybdenum and 392 for cobalt. The belowground/aboveground concentration ratio ranged between 0.9 and 69.5 with an average value of 19. Due to average aboveground/belowgroundbiomass ratio > 1, the belowground/aboveground standing stock ratios were lower with 6 elements (Ba, Zn, Se, Hg, Mo, Mn) having this ratio < 1.
