“…Specifically for Zn, the highest concentration in the summer could be related not only to the higher rainfall of this period, but also to reproduction (Casarini et al, 2010), since reproductive peaks were identified in January (Galvão et al, 2009). For the Mytilus edulis mussel, higher concentrations of Zn were observed in the spawning stage, which is attributed to the synthesis of a group of proteins, such as metallothioneins that are responsible for the preferential accumulation of some metals (Carvalho et al, 2001).…”

“…In Cocanha beach, concentrations of Cd were recorded in the spring, and of Fe in the summer (Catharino et al, 2008), besides Cd, Cr, Fe, and Pb in the spring, and Zn in the winter (Catharino et al, 2012).…”

“…The study area is located in salt water, according to a resolution of the Conselho Nacional do Meio Ambiente (Conama, 2005). The main sources of direct pollution in this area are sewage systems, launched by the Santos submarine emissary and by the urban drainage channels, and dredged sediments of the port channel which were previously improperly dumped into the bay (Casarini et al, 2010). According to 40-year-data from the Instituto Nacional de Meteorologia, for the region of study, the highest accumulated monthly rainfall occurs in the summer (Pellegatti & Galvani, 2010).…”

“…The region is home to the largest port in Latin America (Porto de Santos) and an industrial pole with steel, petrochemical and fertilizer industries, which is the main source of chemical pollutants for the rivers, estuary system, bay, and adjacent marine environments, both for the diversity and quantity of substances currently emitted, and for the past contamination that constitutes an environmental liability (Casarini et al, 2010).…”

“…In Santos Bay, P. perna is the most abundant bivalve (Henriques & Casarini, 2009) and, even with the presence of contaminants, its extraction from natural banks for consumption and commercialization occurs (Casarini et al, 2010). There is a lack of scientific data related to the content of metal trace elements in mussels in tropical regions, specifically in Brazil (Ferreira et al, 2013), regarding the effect of seasonal and physiological variations related to bioaccumulation.…”

-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. Elementos-traço metálicos em mexilhões da Ilha Urubuqueçaba, na Baía de Santos, BrasilResumo -O objetivo deste trabalho foi verificar a existência de bioacumulação em mexilhões da espécie Perna perna, por meio da determinação da concentração dos elementos-traço metálicos, na Ilha Urubuqueçaba, na Baía de Santos, Santos, SP, Brasil. Os mexilhões foram coletados em bancos naturais e costão rochoso, e as amostragens ocorreram no período de abril de 2010 a junho de 2011. 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.
