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.

TL;DR: It is shown that metal pollution in the Elefsis Bay (the most polluted coastal area) causes relatively medium levels of oxidative stress in tissues of mussels due to cellular oxy-radical generation and can be used as potential biomarkers of toxicity for long-term monitoring in marine coastal ecosystems.

TL;DR: The synergistic effect of transition metals and persistent quinoid and semiquinone radicals for the generation of ROS without the presence of H2O2 is investigated, suggesting that the cytotoxic and carcinogenic potential of PM can be partly the result of redox cycling of persistentQuinoid radicals, which generate large amounts of ROS.

TL;DR: The results of this study underlined the importance of local emission sources, especially vehicular traffic, central heating and other local anthropogenic emissions, for reducing traffic-related air pollution in Athens.

TL;DR: Results indicated that mussels stimulated the increase in antioxidant enzyme activities as an adaptive response to metals’ oxidative damage, however, these increases were not adequate to prevent oxidation of membrane lipids of soft tissues.
