Opencast coalmine effluent contains higher concentrations of Cd, Cr, Co, Ni and Pb. Biofiltration of these metals has been demonstrated successfully with the help of aquatic macrophytes i.e., E. crassipes, L. minor and A. pinnata. Experiments revealed E. crassipes reduced highest concentration of heavy metals followed by L. minor and A. pinnata on 20th days retention period. Plant tissue analysis revealed higher accumulation of metals in roots than leaves. Highly significant correlations have… Expand

Phytoremediation potential of aquatic herbs from steel foundry effluent
Discharge of industrial effluents in aquatic environments is a serious threat to life due to toxic heavy metals. Plants can be used as cheap phytoremedients in comparison to conventionalExpand
Phytoremediation of the coalmine effluent.
TLDR
It is suggested that both the plants are suitable for bioremediation of mine effluent at the contaminated sites, however, attention for quick disposal of these metal loaded plants is urgently required. Expand
Comparative studies of the phytoextraction capacity of five aquatic plants in heavy metal contaminated water.
TLDR
The chlorophyll and the carotenoids levels decreased under the stress of heavy metals in both systems, while protein content increased under the influence of Cu2+ and Cd2+, but decreased for Zn2+. Expand
The Influence of Heavy Metals on Growth and Development of Eichhornia crassipes Species, Cultivated in Contaminated Water
Many plants are capable of accumulating heavy metals (called hyperacumulators), one of which is the water hyacinth Eichhornia crassipes Mart. The roots of this water plant naturally absorbExpand

Rhizofiltration: the use of plants to remove heavy metals from aqueous streams.
TLDR
Dried roots were much less effective than live roots in accumulating Pb and in removing Pb from the solution, and Pb removal was based on tissue absorption and on root-mediated Pb precipitation in the form of insoluble inorganic compounds, mainly Pb phosphate. Expand

Seasonal variation of Zn, Pb, Cu and Cd concentrations in the root-sediment system of Spartina maritima and Halimione portulacoides from Tagus estuary salt marshes.
TLDR
It was concluded that H. portulacoides is a more effective accumulator of metals than S. maritima, and both root-sediment systems exhibited a seasonal variation of metal concentrations. Expand

Metal accumulation in aquatic macrophytes from southeast Queensland, Australia.
TLDR
Comparison between morphological tissues of the sampled plants found that roots consistently presented higher metal concentrations than either the stems or leaves, however unlike previous studies, this investigation revealed no consistent trend of stems accumulating more metals than the leaves.

Influence of temperature and salinity on heavy metal uptake by submersed plants.
TLDR
Metal concentrations at high temperature or low salinity were up to twice those found at low temperature or high salinity, and plant biomass affected the metal uptake, with low biomass plants having higher metal concentrations than did high biomass plants. Expand
