The ability of mangrove (Avicennia) to absorb heavy metal has been known. This study aims to determine whether there are differences of absorption level of nonessential (Pb) essential (Cu) heavy metals in Avicennia marina from different location, based on distance of pollutants sources (downstream) toward to the mouth of Porong River Estuary at Sidoarjo. Results showed that accumulation of Pb in the roots and leaves was ranged from 0.0044 to 0.139 ppm and from 0.004 to 0.019 ppm respectively, while in sediment was ranged from 0.0560 to 0.0660 ppm. The accumulation of Cu in the roots and leaves was ranged from 0.07 to 0.415 ppm and 0.0318 to 0.2520 ppm while in sediments was from 0.2930 to 0.381 ppm. The highest concentration of Pb and Cu were found from sediments followed by roots and leaves. The high concentration of heavy metal (Pb and Cu) in the root is likely due to sediment size. The high concentration of heavy metal (Pb and Cu) in the root is likely due to sediment size. When the size is finer, heavy metal accumulation will be higher, although there was no significantly different from different location.

Mangrove forests are in severe threat from heavy metals pollution stimulated by the several human activities connected with hasty industrialization and urbanization. Heavy metals contamination of mangrove ecosystems has caused serious concern worldwide. The objective of the present research is to identify the heavy metal pollution in the mangrove forest sediments of the Gulf of Khambhat, Gujarat, India. The samples were collected from the 12 selected sites of the GoK and investigated for Pb, Cu, Cd, Cr, Ni, As, Co, Mn, Zn, and Hg using Inductively Coupled Plasma Mass Spectrometry. The abundance of heavy metals concentration in the sediment were found in the decreasing order of Mn >Zn>Cr>Ni>Cu >Pb>As>Co>Hg>Cd with average concentration of 669.07, 84.02, 48.19, 34.66, 11.64, 7.14, 2.79, 0.25, 0.12, 0.09 mg/kg respectively. The contamination status of each metal in the sediment of GoK was assessed by various pollution indices and assesses their prospective ecological risk to the environment. The pollution indexes confrmed that Zn and Hg moderately contaminated the surface sediment of GoK due to anthropogenic activities. The concentration of the significant metals described in this study would be helpful as a reference point for assessment in future sediment quality research.
Heavy metals in mangrove sediments along the Selangor River, Malaysia
Forest and Society
Mangroves are woody plants that grow at the interface between land and sea in tropical and subtropical latitudes where they exist in conditions of high salinity, extreme tides, strong winds, high temperature, and muddy anaerobic soils. The objectives of this study were to determine the selected heavy metals Copper (Cu), Zinc (Zn) and Lead (Pb) contamination in mangrove sediments at the Selangor River, Kampung Kuantan, Kuala Selangor, Selangor, Malaysia; and to compare heavy metals content in mangrove sediments between different plots and different sediment depths. Physical properties (sediment texture and sediment moisture) and chemical properties (pH water, electrical conductivity, and selected heavy metals) of sediments were determined by different plots and depths. The element of Pb was analyzed using the Inductively Coupled Plasma (ICP), whereas Cu and Zn using the Atomic Absorption Spectrometer (AAS). Data obtained were analyzed using the Statistical Analysis System (SAS) versi...

Heavy metal contamination has threatened India's biodiverse-rich coastal wetlands, backwaters, rivers, estuaries and mangroves due to unscientific industrial activities and urbanisation. Among the Indian states, the Cochin city is the commercial and economic hub of Kerala along the coastal belt of Arabian Sea. Mangroves located are on the backwater channels and along the banks of Cochin estuary are near victims of this commercialization. Therefore, a comprehensive analysis of the sediment quality focusing on heavy metal contamination and pollution problems are documented from the mangrove habitats of Cochin, considering their immense ecological services offered to the coastal communities with an insight for future restoration activities. Out of the 17 metals analysed, concentration of 6, largely exceeded NOAA effect range low (Cr (5.5-202), Cu (0.89-40.68), Cd (0-1.34), Hg (0-0.68)) and effect range medium (Ag (0-4.68), Ni (0.06-64.5)), which marks the probability of adverse biological effects on mangrove plants and animals. Enrichment factor analysis revealed extremely severe enrichment of Ag (EF = 133), Hg (18.8), Pb (17.8) and Cd (17) and was supported by PCA analysis, that clearly derived the anthropogenic influence of Ag, Cd and Hg in mangroves. Contamination factor, geoaccumulation index and pollution load index revealed that the mangrove sites of Cochin are nearly stressed due to contamination (CF = 66.8) and extreme pollution effects (I geo = − 1.8-5.4) due to silver, and considerably contaminated (CF = 4.4) with Cd especially in Aroor and Vypin zones. However, Valanthakad zone was almost free from metal pollution having better sediment quality where mangrove vegetation had luxuriant growth.

Human and industrial activities in the area of Manyar Subdistrict Mangrove Waters, Gresik District can increase pollution and the presence of heavy metals in aquatic environments and aquatic organisms. This triggers input of heavy metals, especially Pb and Cu. Mangroves can accumulate and have a high tolerance for heavy metals so they can be used as plants for phytoremidiation purposes (phytostabilization). The mangrove ecosystem can be used as a control of heavy metal pollution and can also be used as a pollutant trap. This study was conducted to determine the potential of phytoremidiation based on the accumulation and translocation of heavy metals in Avicennia marina mangroves in absorbing heavy metals Pb and Cu from their environment. Based on research results MacFarlane et al., (2007) mangrove Avicennia marina is one of the plants that can effectively accumulate heavy metals due to its root system. The sample was analyzed using AAS (Atomic Absorption Spectrophotometer). The research parameters include levels of Pb and Cu metals in sediments, mangrove roots and leaves. The results of Pb heavy metal concentrations ranged from 0.30-4.84 ppm and Cu ranged from 0.27-11.42 ppm with the highest values found in sediment stations 2. Avicennia marina at the study site was excluder because the BCF value < 1 which ranged from 0.02-0.18 ppm and phyto-extraction because the value of TF > 1 ranged from 0.35 to 1.69 ppm. The results of this study indicate that Avicennia marina mangroves can be developed into phytoremidiation agents because they are able to absorb and transfer heavy metals from the environment to other body tissues.
ACCUMULATION OF HEAVY METALS IN MANGROVE SEDIMENTS OF CHUMPHON PROVINCE, THAILAND
The objective of this study was two-fold: to examine the heavy metal (Cd, Cu, Cr, Ni, Mn, Pb and Zn) levels that have accumulated in mangrove forest sediments in Chumphon Province, Thailand, and to determine the relationship between heavy metals and the physiochemical properties of sediment. The sediment was digested with HNO3 and HCl using a milestone microwave digestion system (model MLS-1200 MEGA), followed by the addition of 50 ml distilled water. The concentrations of Cu, Cr, Ni, Mn, and Zn in the filtered and digested samples were determined by air-acetylene flame atomic absorption spectrophotometry (FAAS, model Varian SpectrAA 220FS). Cd and Pb were analyzed by a graphite furnace atomic absorption spectrophotometer (GASS, model Varian SpectrAA220). The accumulation of heavy metals originated largely upstream and decreased towards the canal mouths. The highest levels of heavy metals were found at E-let canal (Thung Kha Bay). The heavy metals present in our study area, listed from the most to least prevalent, were Mn, Cu, Zn, Cr, Ni, Pb, and Cd. A striking relationship was found between heavy metal type and sediment physiochemical properties (pH, OM, EC, and CEC).
Heavy Metals Dyanamics and Source In Intertidal Mangrove Sediment of Sabah, Borneo Island
EnvironmentAsia, 2010
There is increasing concern about the impact of anthropogenic activities in many tropical coastal areas such as in mangrove forest. Heavy metal cycling is a serious problem faced in mangrove environments due to the anthropogenic activities. This study was carried out to investigate the dynamics of heavy metals dynamics concentration. The results revealed relatively higher concentrations of heavy metals at high tide compared to low tide due. This observation is complex by other factors such as redox condition, presence of hydroxides and oxyhydroxides. The major source of heavy metals in mangrove surface sediment is anthropogenic such as from agricultural, aquaculture and industrial activities. This finding has updated knowledge about intertidal role on heavy metal dynamics in tropical mangrove sediment. The results also influence the concern of using mangrove ecosystems to be an alternate low cost wastewater treatment system.

This study was an attempt to understand the role of biogeochemical processes in controlling the heavy metal distribution in the mangroves and to assess heavy metal pollution load (viz. Cr, Fe, Mn, Co, Ni, Cu, Zn, Cd, and Pb) in the Gulf of Kachchh, India. Various biogeochemical processes and anthropogenic factors were playing an important role in altering the concentration of heavy metals in the sediments. A significant correlation of Mn, Fe and Pb with Zn implies the role of diffused anthropogenic activities. The organic carbon content (1.47-3.25 %) and clay content (0.1-2.5 %) seem to play a significant role in the metal concentration. Factor analysis suggested two different processes, Factor I strongly indicating anthropogenic activities and Factor II indicating the combination of natural, marine in situ reduction processes (biogeochemical) with partial anthropogenic influence. The enrichment factor (EF) and Geochemical Index (
Mangroves are one of the most biologically important and productive ecosystems in the world. Heavy metals are known to pose a potential threat to terrestrial and aquatic biota. However, little is known on the toxic levels of heavy metals found in mangrove plants in India. To understand heavy metal toxicity, we analyzed heavy metals accumulation in sediment samples collected from surrounding root zone and in the leaves and stem of sixteen different plant species in the Bhitarkanika mangrove forest reserve in Odisha, India. Bhitarkanika mangrove ecosystem receives heavy metal pollution from upstream areas of Brahmani and Baitarani estuary. Few studies were carried about the capacity of mangrove plants to take up and store heavy metals in them. Hence, current investigation was carried out to analyze trace metal accumulation in sediment and plant parts such as stems and leaves of different mangrove plants by Atomic Absorption Spectroscopy (Shimadzu, AA-6300). The heavy metal concentration in sediment was found to be in the range of 5.99 to 92.00 µg/gm. Metals concentration in sediment samples during the study was in the order of accumulation : Zn>Cu>Pb. The accumulation of heavy metal was higher in stem as compared to leaf.
