Ulva lactuca, also known as sea lettuce, is widespread membranous green algae grown in salt water. It is consumed largely in Europe and there is limited information on trace element content of Ulva lactuca samples from the Black Sea, Romania.
We analyzed Ulva lactuca from 3 locations of the Romania Black Sea coasts for heavy metals content, antioxidant capacity and total polyphenolic content to identify if the consumption of this species is potentially harmful or predominantly healthy.
In this study, the levels of heavy metals (iron, zinc, manganese, copper, cobalt, nickel, cadmium and lead) in marine algae (Ulva lactuca) samples from the Black Sea, were determined by flame atomic absorption spectrometry (FAAS), total antioxidant activity (TAC) using CUPRAC method , and total polyphenols content (TPC) by Folin Ciocalteu method.
The results prove that marine algae samples to be analyzed more often with respect to toxic elements composition and to constantly inform the possible consumers about the potentially toxic levels of the trace elements
