Toxicity and bioaccumulation potential of Cr (VI) and Hg (II) on differential concentration by
Eichhornia crassipes in hydroponic cultureIn this work, the phytoremediation of Cr (VI) and Hg (II) ion from water by an aquatic plant Eichhornia crassipes has been studied. Plants were cultured in a double distillated water with modified Hoagland’s nutrient solution at pH 6.8 supplemented with 0, 0.75, 1.50, 2.50, and 4 mg Cr/L as potassium dichromate (K2Cr2O7) and 0, 5, 10, 15, and 20 mg Hg/L as mercuric chloride (HgCl2). They were ...

Effects of cadmium and arsenic on Pteris vittata under hydroponic conditions
Pterisvittata is known to hyperaccumulate arsenic, and a large number of studies on this fern species can be found in the literature aimed at evaluating its behavior when coexposed to other toxic elements. In the present study, P.vittata was treated with different concentrations of As and/or Cd in a hydroponic system, that is, under complete bioavailability of the elements, with the objective of ...

Herbage, phosphorus, and nitrogen yields of winter-season forages on high-phosphorus soil
In climates where cool seasons can produce a forage crop, annual grasses and forbs can be used on dairies to recycle nutrients back to the animals and to phytoremediate soils high in P or N. In north-central Texas, on a Windthorst fine sandy loam (fine, mixed, thermic, Udic Paleustalf) with 250 mg P kg–1, an on-dairy trial measured yields of dry matter (DM), N, and P, as well as fiber fractions ...

Aluminium accumulation in Pteris cretica and trace element uptake in vegetation growing on an abandoned aluminium smelter site in Knoxville, TN, USA
Smokey Mountain Smelters in Knoxville, Tennessee USA is an abandoned aluminium smelter where smelter waste (slag) was dumped on site. ICP analyses indicated the highest slag metal concentrations were 223,000 mg kg−1 Al, 281 mg kg−1 As, 132 mg kg−1 Se, and 2910 mg kg−1 Cu. Metal uptake was quantified in plants growing on slag. Our data indicates that P. cretica accumulates Al in high ...

Advances in phytoremediation
Phytoremediation has many proponents to treat widespread chemical contaminants in soil, water, and air. It is low-cost, eco-friendly, and doesn’t require complicated technology and infrastructure. As it is a new branch of science, it is necessary to understand the processes involved in the different methods of phytoremediation to advise decision-making for application of this technology. ...

Treatment of urea manufacturing facility effluent by Hopea odorata and Khaya ivorensis
Phytoremediation is an environmentally friendly and sustainable alternative for treatment of nitrogen-enriched wastewaters. In this study, Ta-khian (Hopea odorata) and Lagos mahogany (Khaya ivorensis), two tropical timber plants, were investigated for their performances in treatment of urea manufacturing factory effluent with high nitrogen (N) content. Plant seedlings received four ...

Plant Sciences in Agriculture
Plant pathogens Microorganisms, also called as microbes, live in every part of the biosphere, including soil, water, and air. Plant pathogens are the microbes that infect plants and cause diseases. In history, some plant diseases led to tremendous negative impacts on society. In 1845, potato blight disease was prevalent in all potato growing regions in Ireland. Phytophthora infestans, a fungus, ...

Ecotoxicological responses of three ornamental herb species to cadmium
Cadmium is one of the most toxic elements. The ideal vegetal cover should be ensured by the selection of appropriate plant species for successful phytoremediation. In the present study, the ecotoxicological effects of Cd on the following 3 ornamental herbs were investigated: Italian ryegrass (Lolium multiflorum Lam.), white clover (Trifolium repens L.), and alfalfa (Medicago sativa L.). Based ...

Chelant-assisted accumulation of Cd, Cu and Zn in rapeseed (Brassica napus L.) biomass as a renewable energy feedstock.
This article discusses the environmental concerns regarding soil contamination by heavy metals and the possibility of growing a high biomass-yielding crop (i.e., rapeseed) as a tool of phytoremediation. The aim of our research was to investigate the growth parameters and the capacity of rapeseed to accumulate Cd, Cu, and Zn from the contaminated soil and to investigate the effects of the chelants ...

Enhancing phosphorus phytoremedation potential of two warm-season perennial grasses with nitrogen fertilization
Phytoremediation or use of plants to extract soil nutrients is a practice used to ameliorate the impacts of excessive soil nutrients. Pensacola bahiagrass (Paspalum notatum Flügge) and ‘Floralta’ limpograss [Hemarthria altissima (Poir.) Stapf & Hubb] were grown in a P-impacted Immokalee fine sand (Mehlich-1 P 30 mg P kg–1) to evaluate increasing N levels on dry matter yield (DMY), forage P ...

Influence of nitrogen fertilizer on Cd and Zn accumulation in rapeseed (Brassica napus L.) biomass
Diffuse soil contamination with heavy metals and Cd in particular is a matter of serious concern. Application of conventional remediation methods usually is not feasible due to the large territories and relatively low heavy metal content. Thus, phytoremediation is seen as an alternative. Rapeseed was grown on Cd and Zn contaminated as well as clean soil under the greenhouse conditions. Solid and ...

The Effect of Wastewater Irrigation on Perennial Energy Crops
Using treated wastewater to irrigate energy crops is a favourable alternative for traditional irrigation, especially on marginal lands or in seasons when water is scarce. Although irrigating crops with reused wastewater (even when used to irrigate non-food crop) not always have social acceptance, considering the amount of wastewater daily available, and its high nutrient loads, it is a ...
