“…Studies in Maryland showed reductions of up to 88% of Nitrate and 76% of Phosphorus after agricultural run-off passed through a forest buffer (Cotron n.d.). Natural forests and planted trees play an important role in protecting water quality as pointed out by many engineers, planners and community leaders as forests are the most beneficial land use for protecting water quality, due to their ability to capture, filter, and retain water (Singh et al, 2010).…”

Presence of heavy metals and other pollutants in the aquatic systems has become a serious problem in many developing countries for environmental scientists and also for agencies engaged in environmental production. In this regard, there has been a great deal of attention given to new technologies for removal of heavy metals from contaminated water because conventional technologies to provide safe and clean water to living beings are not so far implemented. In this manner, the use of plants to remove heavy metals and other pollutants known as "phytoremediation" from the water is relatively cheaper as compared to other expensive engineering operations as plants remove pollutants from water and render them harmless. Five main subgroups of phytoremediation have been identified by the environmental scientists as "Phytoextraction, Phytodegradation, Rhizofiltration, Phytostabilisation and Phytovolatilisation". The identification and selection of plants that are suitable for successful remediation of water pollution is a matter of great concern. It is recommended that plants that have long and extensive root system should be planted at sites which are polluted due to industrial and sewage water.

“…Acacia (Acacia mangium), neem (Azadirachta indica) and eucalyptus (Eucalyptus hybrid) are known to be suitable plants for removal of nutrient pollutants from primary treated wastewaters [8]. Similarly, shisham (Dalbergia sissoo L.) and African mahogany (Khaya senegalensis) seedlings have been applied successfully for municipal effluent phytoremediation [9,10]. Relatively greater growth and productivity together with higher foliage mineral content caused the lowest concentrations of the nutrients in the soil associated with these species.…”

Urea manufacturing discharge contains a high load of nitrogen, a pollutant which needs advanced technologies to be reduced to desirable levels. However, these advanced technologies are expensive due to the complex process and cost of chemicals and maintenance. Phytoremediation has been recently considered for N removal from various wastewaters. However, the common phytoremediation plants (reeds and grasses) are not able to remove N effectively due to the recyclable nature of N through decomposition processes. Therefore, they require periodic harvestings which impose a high cost on system. In this study, the growth and phytoremediation potential of teak (Tectona grandis), a tropical timber plant, to treat the urea manufacturing wastewater was evaluated. Eight month old teak seedlings received 4 different concentrations of N in bench-scale constructed wetlands every 4 days for 8 weeks. The solution volumes supplied to each container and plant biomass, N recovery, and tissue nutrient concentration were measured. Teak plants showed an escalation in wastewater N uptake with increasing amount of supplied N. Total dry weight was positively correlated with total N supplied. Teak seedlings showed a considerable potential for removing nitrogen when they were supplied with up to 5 g N per pot volume (4 dm 3 ) during a two-month experiment.

“…This tree is able to strive well in a high salt and acidic conditions and other harsh conditions including drought. It is a hyperaccumulator of Mn and Pb Singh et al (2010). found out that E. camaldulensis showed high productivity and great reduction in most soil mineral concentrations in an experiment done to assess mineral uptake of Acacia nilotica L. (babool), Dalbergia sissoo L. (sissoo) and Eucalyptus camaldulensis seedlings.…”

Phytoextraction and Phytostabilisation Approaches of Heavy Metal Remediation in Acid Mine Drainage With Case Studies: A Review

This review discusses phytoextraction and phytostabilisation of acid mine drainage (AMD) alongside with their benefits and limitations with case studies. Furthermore, plants associated with these two approaches of phytoremediation and impact of AMD on aquatic macrophytes used for phytoremediation were also reviewed. Both phytoextraction and phytostabilisation approaches are promising technologies in remediating AMD. However, their limitation of low metal removal and the lack of knowledge of minimum amendments required for their effective remediation call for the proposal, herein made, to combine aquatic macrophytes, as well as include plants from a wide range of families capable of phytoextraction and phytostabilisation in the remediation of AMD.
