“…Acorn barnacles Semibalanus balanoides, Elminius modestus and Lepas anatifera from coastal waters of North Wales (UK) accumulated high concentrations of Zn in their soft tissues, mainly in granules of the midgut, which directly reflected environmental concentrations (Walker et al 1975). Other studies also concluded that different species of barnacles can be successfully used as biomonitors of metal availabilities in coastal waters and had good spatial discrimination (Rainbow et al , 2002(Rainbow et al , 2004aTurkmen et al 2005;Silva et al 2006). However, acorn barnacle Chthamalus montagui has never been used as biomonitor of metal contamination in coastal waters, and it is the dominant species in the northwest (NW) Atlantic coast of Portugal.…”

The concentrations of seven metals (Cd, Cr, Cu, Fe, Mn, Ni and Zn) were determined in coastal seawaters and soft and hard tissues of the barnacle Chthamalus montagui from the northwest coast of Portugal to assess the potential use of C. montagui as biomonitor of metal contamination. The results of this study showed that C. montagui soft tissues can be used for monitoring metal bioavailabilities in these coastal seawaters: (1) there were significant correlations (p<0.05) between the metal concentrations in soft tissues and their concentrations in seawaters and (2) barnacle soft tissues were sensitive to spatial variation of metal bioavailabilities, accumulating different amounts of metals in different locations. The range of concentrations in tissues were: 0.59-1.7 mg Cd kg −1 , 0.5-3.2 mg Cr kg −1 , 0.72-3.0 mg Ni kg −1 , 1.2-6.7 mg Cu kg −1 , 9-26 mg Mn kg −1 , 214-785 mg Fe kg −1 and 178-956 mg Zn kg −1 ; (3) mean logarithmic bioaccumulation factors (log BAF) of Fe, Cr and Cd were higher, 5.49, 4.93 and 4.46, respectively, than mean log BAFs of Mn, Zn, Cu and Ni, 4.03, 3.97, 3.74 and 3.61, respectively. In contrary, C. montagui shell plates were not a good matrix to monitor metal bioavailability in these coastal seawaters, with no significant correlations (p < 0.05) between metal concentrations in the shell and in seawater. Regarding the high Zn concentrations obtained in the coastal seawaters and C. montagui soft tissues, all seawaters from northwest coast of Portugal should be classified as "moderately/remarkably polluted".

“…In the specific case of P. spekii the regulation should be high, Mn being sequestrated in soft tissues at very high concentrations (6544 µg.g −1 , dry weight) compared to the shell (Chale, 2002). For instance, concentrations in P. spekii tissues are two orders of magnitude higher than those reported for the mangrove oyster Crassostrea rhizophorea (61 µg.g −1 , dw) known for its strong Mn accumulation pattern (Silva et al, 2006). An injection method directly in the pallial cavity or better in the extrapallial fluid cavity may be more efficient to mark the shell, reducing the time for an active sequestration of Mn in soft tissues before being released in the mineralization fluid (extrapallial fluid).…”

Manganese content records seasonal upwelling in Lake Tanganyika mussels

Abstract. Biogenic productivity of Lake Tanganyika is highly dependent on seasonal upwellings of cold, oxygendepleted, nutrient-rich deep waters. We investigated the shell of freshwater bivalve Pleiodon spekii as a geochemical archive of these periodic hydrological changes tuned by the monsoon regime. The results of a three-year-long limnological and geochemical survey of the coastal waters performed on the dissolved and particulate fractions were compared to LA-ICP-MS profiles of Mn in five aragonitic shells from the same lake location. Three shells present very similar Mn/Ca profiles dominated by a peak that matched the concomitant increase of Mn and chlorophyll a in surface waters during the 2002 upwelling, while a shell collected during 2003 dry season detect both 2002 and 2003 upwelling events. Larger shells showing an extremely reduced growth display more than 8 Mn/Ca peaks suggesting at least an 8-year-record of seasonal changes in water composition. We postulate that Mn/Ca in shells record the conjunction of an increase of biological activity with supplied of dissolved Mn and nutriments in coastal waters, resulting in an enhanced assimilation of biogenic Mn-rich particles. By combining the most recent generation of laser ablation system and the powerful High Resolution ICP-MS, the spatial resolution could be improved down to 5 to 10 µm crater size and end up in a better constrain of the relative variations of the annual Mn peaks. Such an approach on P. spekii from Lake Tanganyika has definitively a great potential to provide recent and past records on primary productivity associated with the monsoon climate system.

“…Various activities developed along the estuary surroundings have contributed to the influx of metals into this body of water. Literature reports to anthropogenic input of organic contamination (Souza, 2017) and metals in sediments for cadmium, copper, lead, chromium, nickel and zinc (Guedes, 2003;Sindern et al, 2007;Lima et al, 2010) as well as the level of metals in biomarkers (Silva et al, 2006;Emerenciano, 2008;Brito et al, 2008;Lopes et al, 2013). Because of the concentrations of metals related to anthropogenic activities in sediments from JPR, ecotoxicological studies should be performed to evaluate the possible effects of these contaminants on aquatic organisms.…”

The estuary of the Potengi and Jundiaí Rivers is situated on the coast of the state of Rio Grande do Norte, Brazil, and has a record of contamination by metals and organic contaminants. However, there are few studies regarding the toxic effects of pollution on the aquatic organisms from this area. The objective was to assess the quality of sediments from the Jundiaí and Potengi Rivers, by the use of toxicity tests with the amphipod Leptocheirus plumulosus. The sediments were collected from 4 sites, in 4 different months along 2011. After data analysis, it was possible to observe that the sediments collected close to the most populated areas of Macaíba and Natal (P1 and P3) were toxic. Sediment from the Station 4 did not show toxicity in any of the months studied, despite its urban location near the port of Natal. This result might be related to a low level of organic matter and greater tidal influence, which affect the dilution of the contaminants at this area and can reduce the sediment toxicity. No relationship between rainfall and environmental toxicity was observed.
