Pysiological effects of NaCl on Ceratophyllum demersum L., a submerged rootless aquatic macrophyte
In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated in Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly decreased by NaCl salinity. In general, however, Fe and Mn accumulation showed to increase. As a results, NaCl toxicity disturbed the uptake and translocation of macro and micronutrients in the macrophyt...
متن کاملTrace Elements Removal from Waster water by Ceratophyllum demersum
Trace element contamination in aquatic ecosystems is one of the most important concerning of environmental health. Submerged aquatic plants can be used for the removal of Trace elements. The aim of this study was to investigate how Ceratophyllum demersum could affect on wastewater quality for recycling the wastewater to reuse for other purposes in agriculture and industrial fields. In this surv...

متن کاملDifferent strategies of cadmium detoxification in the submerged macrophyte Ceratophyllum demersum L.
The heavy metal cadmium (Cd) is highly toxic to plants. To understand the mechanisms of tolerance and resistance to Cd, we treated the rootless, submerged macrophyte Ceratophyllum demersum L. with sub-micromolar concentrations of Cd under environmentally relevant conditions. X-ray fluorescence measurements revealed changing distribution patterns of Cd and Zn at non-toxic (0.2 nM, 2 nM), moderat...
متن کاملArsenic accumulation and speciation in the submerged macrophyte Ceratophyllum demersum L.
INTRODUCTION Ceratophyllum demersum L. is a widespread submerged macrophyte in aquatic environments. METHODS Simulation experiments were conducted in the laboratory to investigate arsenic (As) accumulation, speciation, and efflux of C. demersum exposed to arsenate and arsenite solutions. RESULTS Plant shoots showed a significant accumulation of As with a maximum of 862 and 963 μg As g(-1) d...
