TLDR
Differences in responses between polychaetes from UP and P sites suggest that organisms from the polluted site, P, are more susceptible to oxidative stress conditions.About:

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.

TL;DR: The use of antioxidant defenses was efficient in avoiding oxidative damage, as the content of oxidized proteins was not altered and the potential of this new methodology to be used in ecotoxicological studies is shown.

The use of polychaetes (Annelida) as indicator species of marine pollution: a review
TL;DR: This review finds that, while the use of indicator species for a particular pollutant is not simple, polychaetes can provide a useful means of assessing the effects of poor environmental conditions.
Journal ArticleDOI
Effects of estuarine sediment contamination on feeding and on key physiological functions of the polychaete Hediste diversicolor: Laboratory and in situ assays.
TL;DR: The results support the utility of integrating responses at individual and sub-individual level to evaluate potential toxicant-induced changes in key physiological functions of H. diversicolor and to interpret their potential ecological consequences.

Superoxide Dismutase AN ENZYMIC FUNCTION FOR ERYTHROCUPREIN (HEMOCUPREIN)
Joe M. McCord,Irwin Fridovich +1 more
TL;DR: The demonstration that O2·- can reduce ferricytochrome c and tetranitromethane, and that superoxide dismutase, by competing for the superoxide radicals, can markedly inhibit these reactions, is demonstrated.
