“…The correlation matrix showed that concentrations of most of the investigated heavy metals in plants were significantly positively correlated with each other, which supports the previous work by Agoramoorthy et al [24]. This indicates that when plants accumulate one element, it can be expected that they will accumulate other heavy metals as well.…”

“…In recent research, unfortunately, there is very little data on the transfer factor for halophytic plants from natural habitats that could be comparable. Agoramoorthy et al [24] reported average transfer factors of heavy metals found in five halophytes from India. These results are similar with the results of our investigation.…”

Heavy metal content in halophytic plants from inland and maritime saline areas

We investigated the concentration of Aluminium (Al), Cobalt (Co), Chromium (Cr), Copper (Cu), Iron (Fe), Manganese (Mn), Nickel (Ni) and Zinc (Zn) in the root and aboveground organs of four halophyte species (Salicornia europaea, Suaeda maritima, Salsola soda and Halimione portulacoides), as well as in the soil from maritime and inland saline areas. The aim of our research was to evaluate the capability of some halophyte species to absorb different heavy metals and to detect differentiation of heavy metal accumulation within populations from inland and maritime saline areas. Generally, the plant roots had significantly higher concentrations of metals when compared to stems and leaves. Zinc was the only metal with concentrations significantly higher in the leaves than in the root and stem. Populations from maritime saline areas had higher trace root and stem metal concentrations than populations from inland saline areas. Excepting zinc, populations from inland saline areas had higher heavy metal concentrations in the leaves. The factors that affected metal accumulation by halophytes included the percentage of salt in the soil. We also discuss the potential use of these halophytes in phytoremediation.

Eastern part of Segara Anakan Lagoon (E-SAL) is an estuarine ecosystem to dispose industrial waste i.e. lead (Pb) containing waste. The study aims to analysis the distribution of Pb in soil, water and mangrove vegetation matrices. Several parameters including bioaccumulation factor (BAF), translocation factor (TF), leaf morphometric (the effect of Pb for mangrove vegetation) were used to estimate their impact. We developed a pre-design of mangrove zone as a model in reducing Pb cntaminantion in E-SAL. The results showed the distribution of Pb in E-SAL was 0.177 -0.233 mg/L (water), 0.320 -0.780 mg/kg (soil), 4.80-8.67 mg/kg (mangrove root), 2.48-6.96 mg/kg (mangrove stem), and 1.48-4.76 mg/kg (mangrove leaf). The scoring of BAF in mangrove vegetation had value between 22.2-40.1 and TF between 0.9-1.3. The distribution of Pb in soil depths were 8.89 mg/kg (0-50 cm) to 0.56 mg/kg (150-200 cm). The impact of Pb was 2-60 % of leaf damage on surface leafs. The mangrove zone to reduce impact of Pb in E-SAL was Rhizophora apiculata, Bruguiera sexangula, Aegiceras corniculatum and Sonneratia caseolaris as mangrove species in the first zone.

“…It is well known that mangroves have the capacity to act as a sink or buffer to remove or immobilize metals before they reach nearby aquatic ecosystems (Macfarlane and Burchett, 2001). However, the rapid development of agriculture, industrial and traffic practices bring large numbers of heavy metal pollutants to estuarine wetlands, which exert damaging effects on mangrove biodiversity and human health with its persistence, non-biodegradation, toxicity and bioavailability (Agoramoorthy et al, 2008;Tam and Wong, 2000). Therefore, metal contamination in mangrove swamp has received more concern.…”

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.
