Aquatic plants are constantly exposed to various environmental factors that cause reactive oxygen species (ROS) production. One of these factors that endanger the Ohrid Lake’s plants is the accumulation of heavy metals by plants. Various metals like nickel, chromium increase ROS production and with it the malondialdehyde (MDA) values in the plants. The purpose of this research was to evaluate oxidative stress in common reed by measuring the values of MDA and to see the possibility of using of MDA as a biomarker for the assessment of pollution in the Lake Ohrid. Plant samples were analyzed by Health Packer spectrophotometric method. The research conducted on three points at the entrance of Pogradec, at the former factory of ferro nickel and at the village Lin. Although not significant the greater values of MDA (4.83 ± 0.57 µmol/g wet tissue) in stem of common reed had in the factory point. Our results showed that a further study on MDA as a biomarker of lipid peroxidation on various parts of the plant and even in various aquatic plants should be continued in the Albanian part of Lake Ohrid.
