Ceratophyllum demersum üzerine CuO nanopartikülünün etkisi

In recent years, nanoparticles with sizes below 100 nm have been used in numerous commercial applications. Therefore, the development of nanomaterials and their use in various industrial fields causes more pollution of the environment by nanoparticles. Aquatic macrophytes are an important part of aquatic ecosystems. Ceratophyllum demersum with a cosmopolitan distribution is a rootless submerged aquatic macrophyte. In this study, it was aimed to determine some effects of Copper oxide nanoparticles on C. demersum. The macrophytes used in the study were collected from the uncontaminated pond in Gaziantep province. Different concentrations of CuO (0, 25, 50, 100 and 200 mg/L) were applied to the macrophytes after being acclimatized in controlled conditions. Some analyzes were made on macrophytes harvested at the end of the application. It was determined that the contents of protein, total carbohydrate, photosynthetic pigment, total phenolic compound, non-protein sulfhydryl groups of tissues increased with increasing CuO concentration under the effect of applied CuO concentrations. There was also an increase in hydrogen peroxide (H2O2) and MDA contents. As a result, it was determined that the applied CuO concentrations caused some physiological changes in C. demersum.
