Molecular biomarkers of oxidative stress in aquatic organisms in relation to toxic environmental pollutants.
TL;DR: Current knowledge and advances in the understanding of oxidative processes in biological systems are summarized and this knowledge is extended to specific applications in aquatic organisms because of their sensitivity to oxidative pollutants, their filtration capacity, and their potential for environmental toxicology studies.
Journal ArticleDOI
Trace metal concentrations in aquatic invertebrates: why and so what?
TL;DR: The significance of accumulated metal concentrations is discussed in terms of the biological significance, including the attempted recognition of a high or low concentration, and of the applied use of aquatic invertebrates in biomonitoring programmes assessing geographical and temporal variation in trace metal bioavailabilities in aquatic systems.
Journal ArticleDOI
Metallothioneins in aquatic invertebrates : their role in metal detoxification and their use as biomarkers
TL;DR: Information on metallothioneins in three important groups of aquatic invertebrates-the molluscs, crustaceans and annelid worms, and attempted to seek explanations for some of the apparent inconsistencies present in the dataset are collated.

The use of biomarkers to assess the impact of pollution in coastal environments of the Iberian Peninsula: a practical approach
Miren P. Cajaraville,Maria João Bebianno,Julián Blasco,Cinta Porte,Carmen Sarasquete,Aldo Viarengo +5 more
TL;DR: A battery of biomarkers of contaminant exposure and effects are proposed that could be incorporated into programmes monitoring the quality of the coastal environment in the Iberian Peninsula and would be undertaken in conjunction with chemical measures of contaminants burdens in selected sentinel species.

TL;DR: This journal issue includes papers that describe recent advances with regard to the development of the biotic ligand model and represents a distinct milestone in the ongoing evolution of the BLM approach and, more generally, of approaches to performing ecological assessments for metals in aquatic systems.
