Originální abstrakt

The primary entry point for highly toxic organic forms of mercury, such as methyl-mercury (MeHg) into aquatic food webs is through phytoplankton, predominantly composed by various microalgal species. Understanding the processes of MeHg intake by microalgae, the effects on population size, cell toxicity, bioaccumulation and eventual biotransformation is of greatest importance for human health, since through process of biomagnification this Hg eventually ends up in aquatic wildlife, fish, seafood and eventually human diet. This study was conducted on two extremophile microalgae strains local to southern Spain Coccomyxa onnubense (acidophile freshwater alga) and Dunaliella salina (halophile seawater alga). The exposure experiments were conducted in laboratory scale. The effects of three different concentrations of MeHg were tested during 72 h cultivation. The results are supported by photos from transmission electron microscopy (TEM) and the determination of superoxide dismutase (SOD) enzyme activity
