In search for potential biomarkers of copper stress in aquatic plants

Over the last few decades, use of pesticides and discharge industrial domestic wastewater on water surfaces have increased. Especially, Copper (Cu) pollution in aquatic ecosystems could constitute a major health problem, not only for flora fauna but also humans. To cope with this challenge, environmental monitoring studies sought to find Cu-specific biomarkers terrestrial and/or fauna. This review discusses toxic effects caused by Cu growth development plants, special focus plants. While copper is considered as an essential metal involved vital mechanisms when excess it becomes causes alterations biomarkers: biochemical (oxidative stress, pigment content, phytochelatins, polyamines), physiological (photosynthesis, respiration, osmotic potential), morphological. In addition, has detrimental effect DNA hormonal balance. An overview toxicity detoxification plants provided, along information regarding bioaccumulation transport. Awareness potential these reactions specific contamination indeed become essential.
