  We examined bioaccumulation of Cu, Cr and Ni and their effects on oxidative stress parameters in the green alga Ulva lactuca to determine at a Jeddah City, in order to determine their bioindicators potential.Concentrations of the selected elements (Cu, Ni and Cr) in algal tissues were 16, 24 and 11-fold higher than that in water.Algae collected from seawater had 40% lower total chlorophyll content when compared with controlled algae. On the other hand, lipid peroxidation and H2O2 content were increased in algae collected from seawater by 2-fold each when compared with controlled algae. Antioxidant enzymes showed difference in response, while SOD and POX were increased by 51 and 35%, respectively, CAT showed a decrease by 37% when compared with controlled algae. Our data prove that the toxicity levels of environmentally monitored or exposed heavy metals in algae can be simply and accur.. Read More»
