Biochemical blood parameters: are they effective biomarkers of chronic toxicity?

The use of biomarkers has become attractive and useful for monitoring environmental quality and health of fish inhabiting polluted ecosystems. Among them, plasmatic biochemical parameters could be a promissory indicator of fish health condition. The question that comes up is if plasmatic biochemical levels could be a tool in a long-term evaluation of the fish stress responses.

Biochemical blood parameters: are they effective biomarkers of chronic toxicity?

The use of biomarkers has become attractive and useful for monitoring environmental quality and health of fish inhabiting polluted ecosystems. Among them, plasmatic biochemical parameters could be a promissory indicator of fish health condition. The question that arises is if these parameters can be applied to chronic toxicity. In this study we investigated the use of plasmatic biochemical parameters as indicat...

PAHs and metals in a coastal lagoon (Esmoriz/Paramos), Portugal

Esmoriz/Paramos is a coastal lagoon on the northwest coast of Portugal with an area of approximately 5.6 km2 and occasional communication with the sea. This habitat has a great ecological importance due to the characteristics of its fauna and vegetation. For the last 25 years, the wet area of the lagoon has been reduced as well as its biodiversity and at present it is very degraded and in-filled. The transport ...

Fish liver size and CAT activity: are they related to metals bioaccumulation?

Oxidative stress enzymes and mitochondrial bioenergetics in wild Liza saliens e...

The Esmoriz-Paramos coastal lagoon represents an ecosystem of great physical and ecological significance. However, as a result of industrial, agricultural and antropogenic activities this habitat has been progressively degrading over the last decades. The heavy metal contamination is an important factor to the decline of sediments quality and may adversely affect fish health. In the present work the leaping gre...
