AB  - The harmful effects of the reactive species may be due to the increase in their steady state
concentration either by the enhancement of their production rates and/or the decrease of their consumption
rate by antioxidant activity. The ascorbyl radical (A<sup>•</sup>
) can be considered as a final product of radical oxidative
transformations of ascorbate (AH<sup>-</sup>). The ratio A<sup>•</sup>
 content/AH<sup>-</sup> content (A<sup>•</sup>
/AH<sup>-</sup>) has been widely used as an
interesting tool to estimate mild to moderate oxidative transformations, providing a quick and simple method
of diagnosis of stress in the hydrophilic cellular medium. The aim of this work was to summarize studies on
the cellular oxidative condition in algae and invertebrates by assessing the A<sup>•</sup>
/AH<sup>-</sup> ratio under environmentally
changing conditions. The use of indices of oxidative stress increasingly sensitive and, somewhat more specific,
can bring a new light to the still unknown world of oxidative responses in marine organisms
