Biochemical biomarkers and hydrocarbons concentrations in the mangrove oyster Crassostrea brasiliana following exposure to diesel fuel water-accommodated fraction

Aquatic Toxicology, 2011
Understanding the toxic mechanisms by which organisms cope to environmental stressful conditions is a fundamental question for ecotoxicology. In this study, we evaluated biochemical responses and hydrocarbons bioaccumulation of the mangrove oyster Crassostrea brasiliana exposed for 96 h to four sublethal concentrations of diesel fuel water-accommodated

Thiol oxidation of hemolymph proteins in oysters Crassostrea brasiliana as markers of oxidative damage induced by urban sewage exposure

Environmental Toxicology and Chemistry, 2016
Abstract   Urban sewage is a concerning issue worldwide, threatening both wildlife and human health. The present study investigated protein oxidation in mangrove oysters (Crassostrea brasiliana) exposed to seawater from Balneário Camboriú, an important tourist destination in Brazil that is affected by

Growth and allometry of the larval shell of the Brazilian oysterCrassostrea brasiliana(Lamarck, 1819) (Bivalvia: Ostreidae)

Ophelia, 2000
Abstract The Brazilian oyster Crassostrea brasiliana (Lamarck, 1819) is a dominant estuarine benthic species of the Parana littoral (Southern Brazil) and an important economic fisheries resource. In this paper we describe its larval cycle, from fertilization to metamorphosis, in controlled conditions of temperature, food and water quality. Growth rates

Suppressive subtractive hybridization libraries prepared from the digestive gland of the oyster Crassostrea brasiliana exposed to a diesel fuel water-accommodated fraction

Environmental Toxicology and Chemistry, 2012
Abstract Diesel fuel can cause adverse effects in marine invertebrates by mechanisms that are not clearly understood. The authors used suppressive subtractive hybridization to identify genes up- and downregulated in Crassostrea brasiliana exposed to diesel fuel.

Passive biomonitoring study and effect biomarker in oysters Crassostrea brasiliana (Lamark, 1819: Mollusca, Bivalvia) in Santos and Cananéia Estuaries in São Paulo State, Brazil

Journal of Radioanalytical and Nuclear Chemistry, 2014
This study assessed the exposure and effects of trace elements in sentinel organisms, using the bivalve Crassostrea brasiliana in two estuarine areas in Sao Paulo State, Brazil: Santos Estuary and Cananeia Estuary, site of oyster farms, which was used as reference site. Oysters were evaluated for bioaccumulation of As, Co, Cr, Fe, Se and Zn by INAA and

RESISTANCE ANALYSIS OF THE SHELL OF THE BIVALVE CRASSOSTREA BRASILIANA UNDER OCEAN ACIDIFICATION AND METAL EXPOSURE

Calcifying marine organisms respond critically to decreased CaCO₃ saturation due to ocean acidification and metal accumulation, slowing growth and calcification. This study evaluated the effects on the shell structure of the bivalve Crassostrea brasiliana under multiple stressors: marine acidification and sediment Pb contamination.

Temporal and spatial variability in Zn, Cr, Cd and Fe concentrations in oyster tissues(crassostrea brasiliana lamarck, 1819)from Sepetiba Bay, Brazil

Environmental Technology Letters, 1986
Abstract Temporal and spatial variability in metal concentrations (Zn, Cr, Cd and Fe) in soft tissues of the oyster C. brasiliana from Sepetiba Bay and Ribeira Bay were determined for three different periods.Significant spacial differences were observed for Zn and Cd but no temporal variations were detected.
