  abstract = {{M}angrove sediments can store high amount of pollutants that can be more or less bioavailable depending on environmental conditions. {W}hen in available forms, these elements can be subject to an uptake by mangrove biota, and can thus become a problem for human health. {T}he main objective of this study was to assess the distribution of some trace elements ({F}e, {M}n, {C}o, {N}i, {C}r, {A}s, and {C}u) in tissues of different plants and snails in a tropical mangrove ({C}an {G}io mangrove {B}iosphere {R}eserve) developing downstream a megacity ({H}o {C}hi {M}inh {C}ity, {V}ietnam). {I}n addition, we were interested in the relationships between mangrove habitats, sediment quality and bioaccumulation in the different tissues studied. {R}oots and leaves of main mangrove trees ({A}vicennia alba and {R}hizophora apiculata) were collected, as well as different snail species: {C}hicoreus capucinus, {L}ittoraria melanostoma, {C}erithidea obtusa, {N}erita articulata. {T}race elements concentrations in the different tissues were determined by {ICP}-{MS} after digestion with concentrated {HNO}3 and {H}2{O}2. {C}oncentrations differed between stands and tissues, showing the influence of sediment geochemistry, species specific requirements, and eventually adaptation abilities. {R}egarding plants tissues, the formation of iron plaque on roots may play a key role in preventing {F}e and {A}s translocation to the aerial parts of the mangrove trees. {M}n presented higher concentrations in the leaves than in the roots, possibly because of physiological requirements. {N}on-essential elements ({N}i, {C}r and {C}o) showed low bioconcentration factors ({BCF}) in both roots and leaves, probably resulting from their low bioavailability in sediments. {R}egarding snails, essential elements ({F}e, {M}n, and {C}u) were the dominant ones in their tissues. {M}ost of snails were "macroconcentrators" for {C}u, with {BCF} values reaching up to 42.8 for {C}erithidea obtusa. {W}e suggest that high quantity of {A}s in all snails may result from its high bioavailability and from their ability to metabolize {A}s.},
