Hornwort (Ceratophyllum deinersuin) incubated in the presence of 1 mg L−1 14C atrazine in an aqueous nutrient solution became radioactive. Microscopic autoradiography was used to investigate the localization of 14C atrazine in a hornwort/epiphyte system. Radioactivity was present within the plant tissue (and also in the nutrient solution), with larger quantities in mature tissue, including stems compared with young tissue. An irregular distribution of black silver granules (which indicate… Expand
Algae as a Potential Bioremediation Tool Against Atrazine Contamination
Atrazine is a commonly used herbicide worldwide that was declared an endocrine disruptor by the E.P.A. In order research biological methods to reduce the chemical’s presence in the environment threeExpand
Algae as a Potential Bioremediation Tool for Atrazine Contamination
Atrazine is a commonly used herbicide in the United States and the potential risks of use are drawing the attention of scientists. In order to reduce exposure and risk to humans and other largerExpand
Macrophytes and Atrazine in Ponds of Southwest Missouri
Wetlands are often the ultimate destination of agrochemicals. The increased use of these pollutants has resulted in their increased transport, via runoff and spray drift, into wetlands. Atrazine, aExpand
The Utilization of Water Hyacinth (Eichhorniacrassipes) as Aquatic Macrophage Treatment System (AMATS) in Phytoremediation for Palm Oil Mill Effluent (POME)
The need for edible oil has increased resulting with a consequent boost in palm oil production.  As a result, production of palm oil mill effluent (POME) which is one of the by-products of theExpand
Phytoremediation Potential of Three Wetland Plant Species Toward Atrazine in Environmentally Relevant Concentrations
This study focused on assessing the phytoremediation potential of wetland plants toward atrazine in an aquatic environment. Changes in plant biomass and atrazine content were investigated for threeExpand

The combined use of soil amendments and phytoremediation significantly improved the microbial community activity, thus promoting the restoration of the ecosystem. Expand
Assessment of Phytoremediation Efficiency of Coriandrum sativum in Metal Polluted Soil and Sludge Samples
A greenhouse pot experiment was conducted to evaluate the phytotoxic effect of heavy metals (Zn, Cu, Ni, and Cr) on the growth (plant height, plant and seed weight) of Coriandrum sativum and uptakeExpand
Technologies can be generally classified as in situ or ex situ. Treatment of the contaminated material at the site called in situ, while ex situ involves the removal of the contaminated materials toExpand
Xenobiotic Compounds Present in Soil and Water: A Review on Remediation Strategies
Bacterial biodegradation used in land filling and composting are most economical methods which uses both the wild type and genetically modified bacterial strains which are suitable for xenobiotic degradation. Expand
A comprehensive review on phytoremediation of cadmium (Cd) by mustard (Brassica juncea L.) and sunflower (Helianthus annuus L.)
Phytoremediation is an important process in the removal of heavy metals and contaminants from the soil and the environment. Plants can help clean many types of pollution, including metals,Expand


Uptake and Metabolism of Atrazine by Poplar Trees
In whole plant studies, the parent compound atrazine and 14C ring-labeled metabolites were extracted from poplar tissues and analyzed via high-pressure liquid chromatography (HPLC) with UV and radiochromatographic detectors in series. Expand
Fate of Atrazine in Treated and Pristine Accessions of ThreeSetariaSpecies
Two species of Setaria adherens and Setaria verticillata are naturally resistant to field levels of atrazine and are 12 times more resistant than wild-type Setaria glauca, which may be the cause of the enhanced metabolism. Expand
Biodegradation of atrazine under denitrifying conditions
Results of this study suggest that the use of M91-3 in a fixed-film bioreactor may have applications in the anaerobic removal of atrazine and nitrate from aqueous media. Expand
