The NH(4)(+) and NO(3)(-) uptake kinetics by Typha latifolia L. were studied after prolonged hydroponics growth at constant pH 3.5, 5.0, 6.5 or 7.0 and with NH(4)(+) or NO(3)(-) as the sole N-source. In addition, the effects of pH and N source on H(+) extrusion and adenine nucleotide content were examined. Typha latifolia was able to grow with both N sources at near neutral pH levels, but the p...

Loss of nitrogen from the soil-plant system has raised environmental concern. This study assessed the fluxes of nitrous oxide (N2O) in the subsurface flow constructed wetlands (CWs). To better understand the mechanism of N2O emission, spatial distribution of ammonia-oxidizing bacteria (AOB) in four kinds of wetlands soil were compared. N2O emission data showed large temporal and spatial variati...

Biomass and contaminant accumulation and partitioning in plants determine the harvest stage for optimum contaminant uptake during phytoremediation of municipal biosolids. This wetland microcosm bioassay characterized accumulation and partitioning of biomass, nutrients (N and P), and trace elements (Zn, Cu, Cr, and Cd) in cattail (Typha latifolia L.) in a growth room. Four cattail seedlings were...

Abstract The present study gave a preliminary report on the phytofiltration of iron-contaminated waters and aggravation iron uptake by copper supplementation using Typha latifolia L. in constructed microcosms. During experiment, Fe concentrations reduced up to 1.67 ± 0.076 mg L −1 (94.43% removal efficiency) 0.087 0.013 (97.10% 14th day from initial 30 microcosm setups. Iron accumulation plant ...
