“…This species seems to respond reliably to the presence of metal elements usually derived from domestic sewage disposal (Francioni et al, 2004). The use of the P. perna mussel as a biomonitor requires the understanding of its biology and the functioning of the environment, as well as the intensity and distribution of the source of availability (Francioni et al, 2004;Maanan, 2008).…”

-The objective of this work was to verify the existence of bioaccumulation in mussels of the species Perna perna, by determining the concentration of metal trace elements, in Urubuqueçaba Island, Santos Bay, Santos, SP, Brazil. Mussels were collected in natural banks and rocky shores, and sampling took place from April 2010 to June 2011. The concentration of the trace metal elements -aluminum, cadmium, cromium, copper, iron, manganese, nickel, lead, and zinc -was determined according to mussel sex, length, and seasonality classes, in a flame atomic absorption spectrometer. Statistical analyses were applied to the results with the use of the software PAST, with parametric and nonparametric approaches, at 5% probability. In the summer, mussels show the highest concentrations of cadmium, copper, lead, and zinc. Females of P. perna concentrate more copper; for the other elements, there are no significant differences between sexes. The length classes with the highest concentrations are 3.5-5.5 cm for Al and Fe, and 6.5-8.5 cm for Cr.Index terms: Perna perna, bivalve mollusks, bioaccumulation, seasonality.

A concentração dos elementos-traço metálicos -alumínio, cádmio, cromo, cobre, ferro, manganês, níquel, chumbo e zinco -foi determinada de acordo com o sexo, o comprimento e as classes de sazonalidade do mexilhão, em espectrômetro de absorção atômica de chama. Análises estatísticas foram aplicadas aos resultados com o uso do programa PAST, com abordagens paramétricas e não paramétricas, a 5% de probabilidade. No verão, os mexilhões apresentam as maiores concentrações de cádmio, cobre, chumbo e zinco. As fêmeas de P. perna concentram mais cobre; quanto aos demais elementos, não há diferenças significativas entre os sexos. As classes de comprimento que apresentam maiores concentrações são a de 3,5-5,5 cm para Al e Fe, e a de 6,5-8,5 cm para Cr.Termos para indexação: Perna perna, moluscos bivalves, bioacumulação, sazonalidade.

“…39,40 It is considered one of the most degraded ecosystems of the Brazilian coast. 41 Several studies conducted in Guanabara Bay show environmental impacts such as eutrophication, 42,43 high sedimentation rates, 44,45 high concentrations of metals, [46][47][48][49][50][51] and hydrocarbons 25,27,30,52,53 in water, sediment and biota. Among the main sources of pollution to the bay, stand out more than 14,000 industries, domestic sewage discharges with low or no treatment, 14 oil terminals, 2 harbors, 32 boatyards and more than 1000 gas stations.…”

Different clean-up methods to determine isotopic composition of n-alkanes were tested. Sources of organic matter in Guanabara Bay were re-examined through the δ 13 C of individual n-alkanes in surface sediment samples. The n-alkanes were efficiently isolated without significant losses of the compounds of interest. The δ 13 C of n-alkanes (n-C 17 to n-C 35 ) ranged between -34.0 and -26.4‰. More depleted δ 13 C values associated to higher carbon preference index (CPI > 4) suggest prevalence of biogenic n-alkanes from terrestrial origin in the inner stations influenced by inputs from mangrove areas. Small isotopic differences between odd and even-numbered chains and 13 C-enrichment in long-chain homologues indicate a petrogenic hydrocarbons contribution. Higher concentrations of short-chain compounds associated to a more 13 C-enriched total organic carbon (TOC) were found near the most intense sewage discharges. Results show that δ 13 C of n-alkanes can be applied to a highly degraded system as the Guanabara Bay and help improve the characterization of the organic matter. Keywords: GC-C-IRMS, UCM, urea adduction, organic matter, Guanabara Bay IntroductionThe composition and distribution of hydrocarbons in sediment samples provide information about the organic matter sources and transformation processes occurring in the environment. 1 Studies on n-alkanes have often been conducted to assess the origin of hydrocarbons, such as biogenic (marine or terrestrial) or petrogenic, found in the marine environment. The assessment makes use of the difference in the n-alkane chain length to draw conclusions on the sources of organic matter. In higher plants, for example, n-alkanes from epicuticular waxes show long chains and an odd over even-numbered carbon chain predominance. 2 Algae are characterized by shorter chain lengths with no expressive odd-over-even preference. 3 In contrast, n-alkanes in fossil fuels have a wide composition range, without predominance of odd or even-numbered chains. 4 However, despite these typical fingerprints, there are cases in which n-alkane profile of different classes of organisms overlap, resulting in ambiguous interpretations of the organic material sources. 5 Given this multiplicity of origins, an interpretation of the different sources exclusively by the concentrations of n-alkanes is very limited in more complex environments. 6 During the last decades, the carbon isotopic analysis of some biomarkers have been widely used as a valuable tool to better distinguish the sources of organic matter in marine environments. 5,[7][8][9][10][11][12][13][14] The carbon isotope composition in the biosynthesized organic material depends on both the isotopic composition of the carbon source used by organisms and the isotope discrimination that occurs during carbon fixation, which includes the steps of absorption and intracellular diffusion, and also the biosynthesis of the cell components. 15 Thus, when two classes of organisms present an overlap in the n-alkane distribution, additional information can b...

“…Os principais cultivos no Brasil ocorrem no estado de Santa Catarina devido a suas características oceanográficas (MARENZI & BRANCO, 2005). As características do mexilhão Perna perna favorecem a absorção e acúmulo de contaminantes, entre eles os poluentes orgânicos persistentes (FRANCIONI et al, 2007), metais (FRANCIONI et al, 2004) e fármacos (CORTEZ et al, 2012), além de absorverem micropartículas de plásticos, já observado na região da baía de Santos, gerando consequências em alterações fisiológicas do organismo (ASCER, 2015).…”
