“…Letters a, b, and c show differences among tissues. Data shown with different letters are statistically significant at p < 0.05 * p < 0.5; * * p < 0.1 (Student's t test); statistical differences between stations agricultural and industrial effluents and harbor operations were the main sources of marine pollution problems in this area (Yilmaz 2003;Cogun et al 2005;Türkmen et al 2005;Firat et al 2008). …”

“…The accumulation of heavy metals in waters and sediments affects various organisms in the environment (Blackmore et al 1998;Storelli and Marcotrigiano 2001;Cogun et al 2005). Mollusks are filter-feeders and thus obtain heavy metals not only from food and water but also from ingestion of inorganic particulate materials.…”

The concentrations of Cd, Cu, Zn, Fe, Pb, Ni, and Co were measured in gastropod mollusks Patella caerulea in the Mediterranean area. The organisms were collected at two coastal sites in Iskenderun Gulf during winter, spring, summer, and autumn 2008. Samples of the digestive gland, gill, and muscle were analyzed for heavy metals. The aim of study is to determine heavy metal levels in tissues of P. caerulea in different locations. Tissues of P. caerulea from the polluted site showed metal concentrations appreciably higher than unpolluted organisms. The highest metal levels were registered in the digestive gland of P. caerulea. Generally, digestive gland and gills showed higher metal concentrations than muscle. The average concentrations of heavy metals analyzed exhibited the following decreasing order: Fe>Zn>Cu>Ni>Cd>Pb>Co for both stations 1 and 2. Seasonal changes in metal concentrations were observed in the tissues of P. caerulea from a polluted and an unpolluted population.

“…Season changes were also assessed by other authors (Mantelatto et al 1999;Ruus et al 2005;Ç ogun et al 2005;Simonetti et al 2012). They observed metal accumulation pattern differences, since its geochemical behavior also depends on drainage basin runoff and salinity.…”

Trace metal distribution in white shrimp (Litopenaeus schmitti) tissues from a Brazilian coastal area

et al. 2016

Biomonitoring in situ was performed in order to assess Sepetiba Bay's Litopenaeus schmitti efficiency as environmental contamination biomonitor, an area historically contaminated by metals and where this shrimp is the second most abundant species. Trawlings were conducted during rainy and dry seasons close to the main pollution sources to evaluate Cd, Cr, Cu, Mn, Pb, and Zn concentrations in muscle, exoskeleton, and whole body. After specimen classification, biometrics measurements, sex and age determination, samples were dried (50°C) and grinded before acid extraction of metals, followed by ICP OES quantification. Concentrations were higher in whole shrimp samples, followed by exoskeleton and subsequently muscle samples. The descending concentration order was Zn [ Cu [ Mn [ Cr [ Cd [ Pb. Comparing previous studies in the area, Pb and Zn concentrations have decreased and Cu has increased. Males and females showed no significant differences. Adults showed higher concentrations of Cr and Zn than juveniles, but bioconcentration factor did not exceed 10 -2 , except for Cu (10 -1 ). Nevertheless, it did not mean intake absence, once concentrations of Cr and Cu reached values above and close, respectively, to the consumption law.

RESUMOEste estudo objetivou avaliar as concentrações de As, Cd, Cr, Cu, Fe, Mn, Ni, Pb e Zn no camarão-rosa Farfantepenaeus paulensis associadas às flutuações nas condições hidrológicas estuarinas, no período de 2006 à 2010. Os organismos foram coletados anualmente e as concentrações de metais foram determinadas no organismo inteiro e na fração abdominal, por espectrometria de absorção atômica.Teores mais elevados de metais foram encontrados no camarão analisado por inteiro quando comparado à fração abdominal. As concentrações de As e Pb analisadas nas duas formas, e de Mn para o camarão inteiro, revelaram valores mais elevados em anos de maior ocorrência de pluviosidade, associada ao fenômeno El Nino. Contrariamente, as maiores concentrações de Cu no camarão inteiro foram observadas quando o estuário apresentou-se dominado por água marinha, característico de períodos de La Niña. Os demais metais analisados nos organismos não estiveram relacionados com os parâmetros ambientais contemplados neste estudo (material em suspensão e salinidade). Palavras-chave: crustáceos; elementos traço; condições hidrológicas. ABSTRACTThis study aimed to evaluate the concentrations of As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn in Farfantepenaeus paulensis associated with fluctuations in estuarine hydrological conditions from 2006 to 2010. Organisms were collected annually and metal concentrations were determined in whole shrimp and edible part by Atomic Absorption Spectrometry. The whole shrimp (soft tissue and shell) under analysis generally exhibited higher concentrations of metals that the edible part. Both forms under analysis showed high levels of As and Pb in years of high occurrence of rainfall associated with El Niño effect. It was also observed for Mn in the whole shrimps analyzed. In contrast, the highest concentration of Cu in the whole shrimp were observed when the estuary was dominated by seawater, characteristic of La Niña periods. The other elements analyzed in the organisms were not related to the environmental parameters considered in this study (suspended matter and salinity). Keywords: crustaceans, trace elements, hydrologic conditions INTRODUÇÃOO camarão-rosa Farfantepenaeus paulensis é uma espécie nativa do Oceano Atlântico Ocidental, que se distribui desde Ilhéus na Bahia (Brasil -14º50'S) até o Mar del Plata (Argentina -38°35'S) (D'Incao, 1995). Seu ciclo de vida apresenta uma fase oceânica, onde ocorre a reprodução e desenvolvimento larval, e outra estuarina, caracterizada pelo desenvolvimento de juvenis até a migração para o oceano, três a quatro meses após sua entrada no estuário (Iwai, 1978;D'Incao, 1991).O estuário da Lagoa dos Patos é considerado o mais importante criadouro desta espécie no Brasil, que se constitui em um dos principais recursos pesqueiros da região Sul, devido ao seu alto valor comercial. A intensa pesca efetuada sobre os juvenis contribui para a redução do estoque adulto, que é considerado sobre-explotado desde a década de 80 e colapsado no início da década atual (D'Incao et al. 2002).
