Piazza, Romi S.; Trevisan, Rafael; Flores-Nunes, Fabricio; Toledo-Silva, Guilherme; Wendt, Nestor; Mattos, Jaco J.; Lima, Daina; Taniguchi, SatieMade available in DSpace on 2018-11-26T16:56:23Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-08-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Understanding the mechanism of phenanthrene (PHE) biotransformation and related cellular responses in bivalves can be an important tool to elucidate the risks of polycyclic aromatic hydrocarbons (PAHs) to aquatic organisms. In the pre...
Hydrocarbons in surface sediments of harbor areas in a tropical region (Ceará s...
Buruaem, Lucas Moreira [UNESP]; Taniguchi, Satie; Sasaki, Silvio Tarou; Bícego, Márcia Caruso; Costa-Lotufo, Leticia VerasMade available in DSpace on 2018-12-11T16:41:51Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-04-01; Sediment samples collected in two harbors of a tropical region of Brazil were investigated for the distribution of linear alkylbenzenes (LABs), aliphatic (AHs) and polycyclic aromatic hydrocarbons (PAHs). The levels of hydrocarbons in sediments from Mucuripe and Pecém harbors were lower than those repor...
Molecular and cellular effects of temperature in oysters Crassostrea brasiliana...
Lima, Daína; Zacchi, Flávia Lucena; Mattos, Jacó Joaquim; Flores-Nunes, Fabrício; Gomes, Carlos Henrique Araújo de MirandaExposure of aquatic organisms to polycyclic aromatic hydrocarbons (PAH), such as phenanthrene (PHE), may increase the production of reactive oxygen species (ROS) and cause changes in the biotransformation systems. In addition, changes in water temperature can cause adverse effects in the organisms. Estuarine species, like the oyster Crassostrea brasiliana, can adapt and tolerate temperature variation. To evalua...
