“…In the present study, constructed wetlands planted with either Kandelia obovata or Aegiceras corniculatum both showed high efficiency in the removal of organic matter and nutrients (Table 1). These results agree with previous findings that mangrove plants, due to their fast growth rate, high demand for nutrients and rich oxygen supply from their extensive roots and aerial root system, are capable of removing wastewater-borne pollutants efficiently (Wong et al 1997, Yang et al 2008, Zhang et al 2010. Constructed mangrove wetland has a high application potential in wastewater treatment.…”

The impact of municipal sewage discharge on the symbiosis between arbuscular mycorrhizal fungi (AMF) and mangrove plants in different sections along 2 constructed mangrove belts was evaluated. Each section was 33 m long and 3 m wide and planted with Kandelia obovata or Aegiceras corniculatum, the 2 most common mangrove plants in South China. A greenhouse experiment comparing the colonization intensity of AMF among different mangrove plant species under wastewater treatment was also conducted. Typical arbuscular mycorrhiza structures were observed in most of the root samples collected from the constructed belts. In both belts, the AMF colonization intensities were significantly lower in the roots of plants close to the inlet than in those further away from the influent, suggesting that the colonization intensity of AMF was inhibited by municipal sewage discharge, and that inhibition was least pronounced in the effluent where the concentration of nutrients was lowest. AMF colonization intensities in the roots of A. corniculatum were significantly higher than those in the roots of K. obovata, which could be attributed to the fact that A. corniculatum provided more oxygen to support the AMF than did K. obovata, indicating the strong effects of the host species on AMF colonization. In both constructed wetland belts and greenhouse experiments, the AMF vesicle and arbuscular structures (the main functional structure of arbuscular mycorrhiza) appeared to be more sensitive to wastewater discharge than the hyphal structure, implying that sewage discharge would reduce the potential beneficial effects of AMF in mangrove ecosystems. This study provides useful information on the responses of AMF to sewage; this knowledge is important for the conservation and restoration of mangrove forests that are located close to human activities.

“…The above results agreed with Yang et al (2008) and Zhang et al (2010). The reduction of nitrate was caused by denitrification, unstable nitrogen (NO 2 -N and NO 3 -N) transforming to N 2 , and by plant uptake (Jenssen et al,…”

“…The above results agreed with Yang et al (2008) which indicated that mangrove forest experimental can reduce total phosphorus 60% and Zhang et al (2010) who pointed that mangrove wetlands has great potential for the removal of nutrients in coastal areas. The reduction of Phosphate in water was caused by abiotic processes which consisted of 1) sedimentation 2) absorption and precipitation and 3) exchanging process between soil and water column (Reddy & D'Angelo, 1977).…”

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.

“…However, plant species differ in their effect on the biogeochemical cycles of metals through organic acid input, cation uptake and change of soil pH and redox (Eviner and Chapin, 2003;Wang et al, 2011). Zhang et al (2010) showed that S. apetala species was more effective in the removal of nutrients and heavy metals, while Akshayya et al (2007) showed that A. marina in comparison with other mangrove species is evident of its adaptability even under polluted conditions. In this study, the concentrations of As, Cr, Cd, Cu, Fe and Ni have no difference between those of A. marina and S. apetala communities, except that the latter has the highest concentration of Mn.…”

“…The reason for these is that heavy metal accumulation in sediments are complicated and often controlled by an array of factors, such as sediment physicochemical characteristics, metal bioavailability, rhizosphere process, mechanism of plant uptakes, the change of land use and pollution sources (Bai et al, 2011;Clemens, 2006;Klavinš et al, 2000;Liu et al, 2014;Remon et al, 2013;Xin et al, 2014). Additionally, the biomass of a plant species plays an important role in the removal of nutrients and heavy metals from mangrove wetlands (Zhang et al, 2010). In all, the interactions of sediment and mangrove plants will influence the distribution of heavy metals in sediment.…”

Sediments in eight types of mangroves were sampled in the Leizhou Peninsula. Heavy metals were analyzed to investigate the effects on metal distribution of mangrove communities, to evaluate contamination levels, identify sources and relationships between the two. Results showed that mangrove communities have effects on most heavy metal distributions in sediments, especially in the sediment with shrub communities of Aegiceras corniculatum where the contents of many metals are highest. As, Cr and Ni were identified as metal pollutants of primary concern, while Cd was of no concern. Zn, Pb, As mainly originated from anthropogenic source while the other metals are geogenic. Heavy metal distributions were affected by the independent and joint effects of landscape and sediment context; landscape context explains more variations in heavy metals than does sediment physicochemical variables. Total sulfur, total phosphorus and total potassium in sediment, and the existence of paddy field and forest land within 2000 m around the sampling sites are significant variables also.
