Bioaccumulation of heavy metals by Phragmites australis cultivated in synthesized substrates.
Accumulation of heavy metals from various oxides with adsorbed cadmium by wetland plant Phragmites australis was studied to evaluate the fate of heavy metals in the sediment of constructed wetlands. Hoagland solution was used as nutrition supply, and single metal oxide with adsorbed cadmium was applied as contaminant to study the accumulation characteristics of cadmium and the substrate metals ...
متن کاملRole of Phragmites Australis for Biomonitoring and Phytoremediation of Heavy Metals Pollution in Badavar River, Lorestan Province (Iran)
Background & Aims of the Study: Aquatic macrophytes, given their rapid growth and high bio mass production, great potential to accumulate heavy metals in their organs. Phragmites australis as a hyper-cumulative plant plays an important role in the bioremediation. The Badavar River of Noorabad, Lorestan province, is exposed to urban wastewater and agricultural runoffs. In order to heavy metals (...

Monitoring of Heavy Metals in Water, Sediment and Phragmites australis of Aras River along the Iranian-Armenian Border
Background: Aras River is the main source of drinking water supply in northwestern provinces of Iran. The present study aimed to determine the concentration of heavy metals in the river on the border between Iran and Armenia. Methods: Three samples were taken from the Aras river water, the river bottom sediments and the root of Phragmites australis. In water sampling, the concentration of Hg, ...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
