Effects of EDTA on Cr +3 Uptake, Accumulation, and Biomass in Nasturtium officinale (Watercress)
A pot study was used to examine the effects of ethylenediaminetetraacetic acid (EDTA) on the growth potential, uptake, and mobilization of Cr by Watercress (Nasturtium officinale) in contaminated water at different concentration levels of the chelating agent EDTA (0, 10-5, and 10-4 M) and four concentration levels of Cr (0, 1, 3, and 10 mgL-1). The EDTA resulted in more solubilization of Cr in water. The application of EDTA 15 d prior to harvest increased the amount of Cr accumulated in watercress with more Cr accumulated by the plants from the media. Nasturtium officinale accumulated high Cr concentration (317 mgkg -1 ) in the root at a concentration of 10 mgL -1 Cr 3+ and 10 4- M EDTA after 15 d growth. The application of EDTA had inhibitory effects on the root and shoot dry biomass compared with that in the
期刊介绍:
Cessation. Ekoloji is an international journal that focuses on papers that report results from original research on all disciplines engaged in the field of environmental research. We welcome articles that cover the entire spectrum of environmental problems and environmental pollutants, whether chemical, biological or physical. Its coverage extends to all environmentally related issues: air and water pollution, solid waste, noise, recycling, natural resources, ecology and environmental protection. It includes articles on basic and applied environmental pollution research, including environmental engineering and environmental health. All types of pollution are covered, including atmospheric pollutants, detergents, fertilizers, industrial effluents, metals, mining wastes, oil, pesticides, plastics, radioactive materials and sewage. It also includes research papers on ecological and environmental issues such as climate change, biodiversity. The primary criteria for publication are scientific quality and ecological/environmental significance.
The journal will be read and contributed to by biologists, applied ecologists, environmental scientists, natural resource specialists, environmental engineers, environmental health specialists, agro-ecologists, veterinaries, agricultural engineers, landscape planners and designers. The journal welcomes full "research papers" and short "research notes", only in the English language.
