“…Brazil (Madi et al 2015), or in Indonesia (Martuti et al 2016). It was reported that the Cu partitioning in sediments of the Can Gio mangrove was mainly related to sulphide precipitation and to its complexes with organic compounds (Thanh-Nho et al 2019).…”

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.

“…Mn concentration in all mangrove and halophytes was far more than the suggested level of 20 ppm (Underwood 1981), particularly, Sonneratia apetala leaves showed significantly high (P<0.05) concentration of Mn (934.95 ppm) among all the recorded plants. Significant correlation between soil and leaf micronutrients was earlier reported by Madi et al (2015). Therefore higher levels of micronutrients in leaf samples might be attributed to higher micro-nutrient concentration in soil.…”

Micromineral status of soil, salt-tolerant plants and goats in tidal estuarine ecosystem of Indian Sundarban

It could be concluded that tidal coastal zones contain high level of micro-minerals in soil and plants. Paradoxically, local goats inhabiting in this particular ecosystem are deficient in Fe, Cu and Mn. This might be an adaptive response of animals in that area. Tanins are well-known inhibitor of Fe absorption from intestine. Regular consumption of tanins and other plant alkaloids during grazing and browsing might also be responsible for low bio-availability of the minerals in the plasma. Further research is warranted to have more insight on mineral status of small ruminants in fascinating ecosystem of Sundarbans.

“…These two sites (HB and CO) of Paranaguá bay are known to be impacted by harbor activities and human occupation (Sá et al, 2006;Choueri et al, 2009;Santos et al, 2009;Martins et al, 2010;Santos et al, 2014). The reference site (RF) is on the Guaratuba bay, a remarkably non-impacted bay, as described by several recent studies (Combi et al, 2013, Rodrigues et al, 2013, Madi et al, 2015, Prodócimo et al, 2015. We transported the fish to a research station right after the sampling, and obtained the total weight (TW) and length (TL).…”

“…Guaratuba bay, used in this study as reference site, is a touristic area and commonly known for low-scale fishing, angling, banana and citrus cultivation, and mariculture (Mizerkowski et al, 2012). Even so, the levels of contamination found are acceptable for the activities aforementioned (Combi et al, 2013;Rodrigues et al, 2013;Madi et al, 2015;Prodócimo et al, 2015).…”

A multi-biomarker approach was used to evaluate the liver health of two Neotropical fish species (Cathorops spixii and Atherinella brasiliensis) that inhabit two different sites of the Paranaguá bay (Paraná-Brazil) and a reference site in the Garatuba bay. Fish were sampled during summer and winter, so the variation of the responses can reflect the actual conditions of sampling sites. Data showed that fish from both sites of the Paranaguá bay are affected by the presence of pollutants from different sources. Both fish species presented adverse biomarker responses mainly in the summer, probably due to the increased human population during the period. Chronic effects in the liver related with the contamination. Thus, the results demonstrated that pollution in Paranaguá bay induce liver damage in fish that inhabit this area.
