Use of Cathorops spixii as bioindicator of pollution of trace metals in the Santos Bay, Brazil

Ecotoxicology, 2009
In the present study Cathorops spixii, was evaluated as a bioindicator fish for trace metal pollution. Concentrations of cobalt (Co), iron (Fe), selenium (Se) and zinc (Zn) were determined by Instrumental Neutron Activation Analysis in liver. Mercury (Hg) and methyl-mercury (MeHg) were analyzed by Cold Vapor Atomic Absorption Spectrometry in muscles ...

Polycyclic aromatic hydrocarbons (PAHs) in Crassostrea rhizophorae and Cathorops spixii from the Caroni Swamp, Trinidad, West Indies

Environmental Science and Pollution Research, 2014
Dietary exposure to polycyclic aromatic hydrocarbons (PAHs) may pose serious threats to human health. However, within the Caribbean, quantitative assessments regarding the risks associated with dietary PAH exposure remain sparse. This study investigated PAH presence in edible biota from the Caroni Swamp and quantitatively assessed the potential health ...

Cathorops spixii (Pisces) gill study through Scanning Electron Microscopy

Proceedings, annual meeting, Electron Microscopy Society of America, 1990
The scanning electron microscope is very useful for the detail three-dimensional external understanding of structures, such as fish gills, that present varied aspects according to systematic position or to adaptations to the environment. Cathorops spixii lives near to muddy bottom, in brackish water, and was collected from the Paranaguá bay in the ...
