Phytoremediation research papers

It is reported that phytoremediation technology is an alternative to treat heavy-metal-contaminated side which will be more admitted in order to remediate the environment. Mine-land restoration: phytoremediation of heavy-metal contaminated sites—a critical view,” international ecological engineering society, :///ecoeng011/ecoeng011_.

Yellow poplars are generally favored by environmental scientists for use in phytoremediation at this time.

Title : phytoremediation of heavy metals laden waste water using duckweed species introduction presservation of the environment quality is one of the major concern of this century.

Some definitions on phytoremediation that have been described by several researchers are listed in table 1: definition of lly, according to the above researchers, phytoremediation is defined as an emerging technology using selected plants to clean up the contaminated environment from hazardous contaminant to improve the environment quality. However, with the use of phytoremediation, the possibility of safe selenium levels has never been closer.

Sigua, “assessing phytoremediation potentials of selected tropical plants for acrylamide,” journal of soils and sediments, vol.

Advantages of phytoremediationphytoremediation techniques may also be more publicly acceptable, aesthetically pleasing, and less disruptive than the current techniques of physical and chemical process [38]. If the daughter compounds are relatively benign, the plants can still be used in traditional most effective current phytoremediation sites in practice combine these three mechanisms to clean up a site.

Sigua, “phy toremediation potentials of selected tropical plants for ethidium bromide,” environmental science and pollution research, vol. Phytoremediation might be best suited for remote areas where human contact is limited or where soil contamination does not require an immediate response [38].

Surface waters, and ground water worldwide, are increasingly affected by contaminations from industrial, research experiments, military, and agricultural activities either due to ignorance, lack of vision, carelessness, or high cost of waste disposal and treatment. Mechanisms of heavy metal uptake by plantcontaminant uptake by plants and its mechanisms have been being explored by several researchers.

Phytoremediation actually benefits the soil, leaving an improved, functional soil ecosystem at costs estimated at approximately one-tenth of those currently adopted technologies [3]. A major limitation in the phytoremediation of toxic elements is the maximal level that can be accumulated by plants.

While the benefits of using phytoremediation to restore balance to a stressed environment seem to far outweigh the cost, the largest barrier to the advancement of phytoremediation could be the public opposition. In chelate-assisted phytoremediation, synthetic chelating agents such as nta and edta are added to enhance the phytoextraction of soil-polluting heavy metals.

Polluted sites are being studied, and phytoremediation looks promising for a variety of academic & environmental sciences > paper is not in the back emediation: a green technology to remove environmental ad as pdf (size:251kb). Phytoremediation is more than just planting and letting the foliage grow; the site must be engineered to prevent erosion and flooding and maximize pollutant uptake.

Success of phytoremediation may be limited by factors such as growing time, climate, root depth, soil chemistry, and level of contamination [38]. Currently, the majority of research is concentrated on determining the best plant for the job, quantifying the mechanisms by which the plants convert pollutants, and determining which contaminants are amenable to phytoremediation.

On the collected data from the phytoremediation research listed in tables 2 and 3, the accumulation of heavy metals as, pb, and hg in plant tissue is summarized in respective, figures 4, 5, and 4: as accumulation in plant 5: pb accumulation in plant 6: hg accumulation in plant ing to figure 4, the highest accumulation of as in plant tissue (the researchers have not detailed which part it is, but it might be the whole plant) occurs in pteris vittata l. Phytoremediation research can also contribute to the improvement of poor soils such as those with high aluminum or salt levels [75].

The generic term “phytoremediation” consists of the greek prefix phyto (plant), attached to the latin root remedium (to correct or remove an evil) [28, 29].

Among them are being time-consuming method, the amount of produced biomass, the root depth, soil chemistry and the level of contamination, the age of plant, the contaminant concentration, the impacts of contaminated vegetation, and climatic 8: the limitation of phytoremediation emediation can be a time-consuming process, and it may take at least several growing seasons to clean up a site. Phytoremediation: using plants to combat a stressed environment plants have long been adapting the traits necessary to survive in a wide variety of stressful environments – including areas of high salinity, extreme heat, drought, and freezing temperatures - but now, using genetic modification, scientists have been able to expand the role that plants play in the environment.
