metadata.value: Coastal marine waters are known as spawning sites of fish and invertebrates,
  which are highly sensitive to crude oil and its derivates in their early developmental
  stages. The aim of the present study was to investigate the effects
  of mazut at concentrations of 0.00001, 0.02, 0.1, and 0.2 ml/l on antioxidant
  enzyme activities in developmental embryos (stage V) of the Black Sea blenny
  Parablennius sanguinolentus. The biomarkers of oxidative stress — namely superoxide
  dismutase (SOD), catalase (CAT), peroxidase (PER) and glutathione reductase
  (GR) — were investigated. This revealed a non-uniform impact of mazut
  concentration on fish embryos. The correlations between enzyme activities
  and mazut concentrations were non-linear, and tested antioxidants fluctuated
  independently from one another. The obtained results can be applied to the
  development of oil toxicity tests for assessment of water quality and in conservation
  biology.
