| Algae have been used as bioindicators by having several advantages such as they have short life cycles, they can take up nutrients directly from water, they are generally easy to collect in sufficient amounts from various habitats; and they readily accumulate compounds present in seawater, making tissue analyses reliable indicators of water quality. In order to evaluate the bioremoval capability of the green alga Rhizoclonium riparium, the photosynthetic responses to heavy metal pollution under different sublethal concentrations of copper was assessed. Photosynthetic rates were significantly low (p <0.05) at low copper concentrations, between (0.01 y 10 mg/l). Maximum photosynthetic values were shown at 30 y 60 mg/l and almost cero at 150 mg/ l of Cu.... |
