Biochemical disturbances in plant cells under conditions of anthropogenic pollution

Currently, the problem of environmental contamination is very urgent. Accumulation of heavy metals by plants leads to biochemical disorder in cells. The concentration of lipid peroxidation products is a suitable parameter for the estimation of damage degree on cell membrane. The aim of this research was to investigate the content of diene conjugates and Schiff bases in plants of various species in the context of urban environment. The content of lipid peroxidation products was determined by the spectrophotometry of heptane extracts in the near-ultraviolet region. All the results were statistically processed; differences between studied samples were determined with Student's t-test with the confidence probability P≤0,05. The study was carried out/done on meadow grass ( Poa pratensis ), red clover ( Trifolium rubens ), wild vetch (V icia cracca ), chamomile ( Matricaria chamomilla), coltsfoot ( Tussilago farfara ) and cultivated oat ( Avena sativa ). Plants were collected in the area of highway, as well as in the areas with metallurgical, motor building, oil refinery and battery factories...
