“…Regarding Ni and Cr, their concentrations in the roots and leaves of Avicennia and Rhizophora in the Can Gio mangrove were in the range of those presented in the review of Lewis et al (2011) but lower than those measured in the Indian Sundarban mangroves (Chowdhury et al 2017) or in New Caledonia (Marchand et al 2016). In the later environments, the authors reported higher Ni concentrations in plants tissues, with values up to 700 µg g -1 due to high Ni concentrations in mangrove sediments resulting from the proximity of lateritic soils enriched in Ni.…”

Mangrove sediments can store high amount of pollutants that can be more or less bioavailable depending on environmental conditions. When in available forms, these elements can be subject to an uptake by mangrove biota, and can thus become a problem for human health. The main objective of this study was to assess the distribution of some trace elements (Fe, Mn, Co, Ni, Cr, As, and Cu) in tissues of different plants and snails in a tropical mangrove (Can Gio mangrove Biosphere Reserve) developing downstream a megacity (Ho Chi Minh City, Vietnam). In addition, we were interested in the relationships between mangrove habitats, sediment quality and bioaccumulation in the different tissues studied. Roots and leaves of main mangrove trees (Avicennia alba and Rhizophora apiculate) were collected, as well as different snail species: Chicoreus capucinus, Littoraria melanostoma, Cerithidea obtusa, Nerita articulata. Trace elements concentrations in the different tissues were determined by ICP-MS after digestion with concentrated HNO3 and H2O2. Concentrations differed between stands and tissues, showing the influence of sediment geochemistry, species specific requirements, and eventually adaptation abilities. Regarding plants tissues, the formation of iron plaque on roots may play a key role in preventing Fe and As translocation to the aerial parts of the mangrove trees. Mn presented higher concentrations in the leaves than in the roots, possibly because of physiological requirements. Nonessential elements (Ni, Cr and Co) showed low bioconcentration factors (BCF) in both roots and leaves, probably resulting from their low bioavailability in sediments. Regarding snails, essential elements (Fe, Mn, and Cu) were the dominant ones in their tissues. Most of snails were "macroconcentrators" for Cu, with BCF values reaching up to 42.8 for Cerithidea. We suggest that high quantity of As in all snails may result from its high bioavailability and from their ability to metabolize As.

“…Looi et al, 2015). Based on geoaccumulation index values, the sediment pollution status can be divided into 6 categories -unpolluted (0-1), moderately to unpolluted (1-2), moderately polluted (2-3), moderately to highly polluted (3-4), highly polluted (4-5), and very highly polluted (> 5) (Chowdhury et al, 2017).…”

“…The canopy structure at managed mangrove sites in MMFR is quite uniform as all trees have the same age and the forest gets a closed canopy after 6 years on average (Otero et al, 2019), while in the Sundarban mangroves the forest structure is much more variable and therefore stems are more exposed to the atmosphere and to Hg deposition. Moreover, Chowdhury et al (2017) have linked the accumulation of Hg in R. apiculata bark with the atmospheric deposition due to burning of fossil fuel and garbage by local people along with agricultural and chemical run-off. No doubt the bark is useful for biomonitoring of airborne Hg pollution (Chiarantini et al, 2016), but it is uncertain for mangroves -at least for the observations made in the present study-and, leaves may be a more suitable indicator of Hg in plant tissues.…”

Charcoal production activities at the Matang Mangrove Forest Reserve (MMFR) in Peninsular Malaysia have a potential to emit volatile compounds such as Hg back into the ambient environment, raising concerns on the public health and safety. The present study was aimed at analyzing Hg concentration from different plant/ animal tissues and sediment samples (in total 786 samples) to understand clearly the Hg distribution at the MMFR. Leaves of Rhizophora spp. showed higher Hg concentration with an increasing trend from young, to mature, to senescent and decomposing stages, which was possibly due to accumulation of Hg over time. The low Hg concentration in Rhizophora roots and bark suggests a limited absorption from the sediments and a meagre accumulation/partitioning by the plant tissue, respectively. In the case of mangrove cockles the concentration of Hg was lower than the permissible limits for seafood consumption. Although the mangrove gastropod-Cassidula aurisfelis Bruguière had rather elevated Hg in the muscle tissue, it is still less than the environmental safely limit.

“…The higher concentration of Mn (1,279.6 mg kg −1 ) and Pb (52.94 mg kg −1 ) in the sediment core DL27 could suggest an influence of anthropogenic activities. It should be noted that heavy metals could enter into the coastal environments from different sources, including disposal of liquid effluents, runoff and leachates from domestic, industrial and agricultural activities [30][31]. In Da Loc coastal area, Len river could transport different pollutants to the downstream and incorporated in mangrove sediments.…”

In order to clarify heavy metal concentration profiles in different mangrove forest ages, four sediment cores (up to 100 cm in depth) were collected and tested for their physicochemical characteristics (pH, Eh, organic matters and grain size) and heavy metal concentrations. Results showed that mangrove sediments were composed mainly of sandy silt, silty sand, silt, sandy mud and mud. The average mud content in the sediment cores continuously increased with mangrove forest ages from one, nine, nineteen and twenty years old, whereas the mud content highly fluctuated with the core depth. pH, Eh and organic matter content implied that the sedimentary depositional environments were classified as weak alkaline and anaerobic. The Cu and Zn concentrations in the sediment cores from the intertidal zone exceeded the TEL values in Canadian Interim Marine Sediment Quality Guideline (ISQGs) values, while, Pb concentration exceeded the PEL level. When compared with National Technical Regulation on Sediment Quality QCVN43:2012/BTNMT, sediment samples were polluted by Cu and Pb.
