“…The reduction of ammonia was caused by ammonification changing of amino acid in treated water to ammonia, Denitrification changing of nitrite and nitrate to nitrogen gas (Gray et al, 2000); volatilization, changing of ammonia to ammonia gas and released into the air, and plant and microbial uptake, in from of nitrate (Reddy & D' Angelo, 1977). It is conform to Wang et al (2010) which indicated that Sonneratia caseolaris and Kandelia candel can reduce ammonia for 50%.…”

The study was aimed to study water quality treated by mangrove forest. This study has been conducted at the mangrove forest site of the King's Royally Initiated Laem Phak Bia Environmental Research and Development Project (the Royal LERD Project), Ban Laem District, Phetchaburi Province, Thailand. The study site, where Avicennia marina is dominant plant, is divided into in 3 areas; (A) the tideland area between constructed pond and mangrove forest, 200 meters from outlet (B) area of mangrove forest, distance 201 to 900 meters from outlet and (C) sea area, started from 901 meters from outlet. Six parameters were investigated; including temperature, pH, dissolved oxygen (DO), phosphate, nitrate, and ammonia. The results showed that water quality from mangrove forest met the effluent standards for coastal aquaculture (Ministry of Natural Resources and Environment, 2004). Mangrove forest can be able to improve water quality by increasing DO by 32.39%, while reducing phosphate, ammonia, and nitrate by 88.23%, 73.77%, and 64.28% respectively. It can be used as an additional natural system to increase the efficiency of man-made wastewater treatment system.

“…Natural wetlands have been used for centuries as a sink for waste, being capable of assimilating large amounts of environmental contaminants (Dinges 1982;Gray et al 2000;Groudev et al 2001c). They act as biological filters and are a viable option for helping to solve a wide range of environmental and water quality problems (Greenway and Simpson 1996;1997a, b).…”

“…While wetland sediments form primary sinks for heavy metals (Gray et al 2000), macrophytes can absorb heavy metals through roots and also shoots. Collins et al (2005) while working on remediation of metal-laden acid mine run-off from a coal storage pile reported that elemental concentrations in plant shoots differed between plants of deep and shallow wetlands; zinc, aluminium, and iron concentrations were higher in shallow wetlands and sodium, manganese, and phosphate concentrations were higher in plants in deep wetlands.…”

We investigated pollutant removal from acid mine drainage (AMD) by three different aquatic plant species (Typha angustifolia, Desmostachya bipinnata, and Sacharum bengalense) in bench-scale wetland test cells of 1 m 3 . AMD was generated in the laboratory using chalcopyrite, galena, and sphalerite ore. A substrate containing 75% soil, 20% powdered goat manure, and 5% wood shavings was used in each cell. The performance of the system was evaluated for different water column heights (100, 150, and 200 mm) and for different retention periods (24, 48, 72, 96, and 168 hrs). The performance of the plant species was different for the various metals of AMD; therefore, multi-species plantings should be considered in constructed wetlands.

“…Sediment is a compartment with a large capacity for pollutants (Salomons and Stigliani 1995) and therefore represents the most concentrated physical pool of trace metals (Pourang 1996). Due to the large amount of organic matter in wetland sediments and its strong binding capacity for metal cations, wetland environments are capable of adsorbing and retaining a significant amount of atmospherically deposited trace elements (Perkins et al 2000) as well as sequestering large quantities of environmental contaminants (Dinges 1982;Gray et al 2000) via various physical, chemical, and biological processes. Trace elements in wetland sediments may accumulate to toxic levels and pose a serious threat to the native plants and animals (Perkins et al 2000).…”

An investigation was performed to measure concentrations of major and trace elements in surficial wetland sediments in the southern Tibetan Plateau in order to assess the sediment quality. Results showed that most of elements have concentrations comparable to those of the Tibetan surface soil (TSS) except for As, Ca, Cs, Sr, and Cu. Correlation analysis indicated that most elements were highly associated with major crustal elements, suggestive of their common natural origin. Sediment quality assessment revealed that the wetlands are unpolluted with most of trace elements except for Cs and As, which are likely associated with organic matters and biological activities. Despite that the wetland sediments are minimally influenced by either local or long-transported anthropogenic pollutants, and no notable trace element pollutants were detected, As was found in elevated concentrations which far exceed the level above which harmful effects on wildlife and humans are likely to be observed.
