Effects of cement flue dust from a cement factory on stress parameters and diversity of aquatic plants.

摘要: Cement kiln dusts, made of a complex mixture elements, include high levels heavy metals such as fluoride, magnesium, lead, cadmium, nickel, zinc, copper, beryllium and some toxic compounds. Because the element compositions radioactive isotope properties cement not only terrestrial but also aquatic ecosystems are subjected to greater stress. In present paper, we investigated effects pollution caused by Askale-Erzurum factory (CF) on stress parameters diversity plants. For this purpose, plant species were collected from outer zone CF. Only three (Lemna minor, Ceratophyllum submersum Potamogeton natans) these able be determined in CF zone. Antioxidant enzyme activities plants measured compared their controls. Superoxide dismutase (SOD) activity P. natans was significantly respective control, while it low L. mi...
