LIPID PEROXIDATION IN PLANTS CELLS UNDER CONDITIONS OF THE URBAN ENVIRONMENT

Currently, the problem of environmental contamination is very urgent. Accumulation of heavy metals by plants leads to biochemical disorder in cells. The convenient parameter for estimation of cells membrane damage degree is the concentration of lipid peroxidation products. The aim of this research was to investigate the content of diene conjugates and Schiff bases in plants of various species under conditions of the urban environment. The investigation was conducted with meadow grass, red clover, wild vetch, chamomile, coltsfoot and cultivated oat. Plants were collected from highway area and from areas with metallurgical, motor building, oil refinery and accumulator factories. It was discovered that reaction of plants cells membrane damaging was species-specific: chamomile, wild vetch, meadow grass accumulated lipid peroxidation products. The concentration of diene conjugates and Schiff bases in cells of red clover and coltsfoot was lower than in control group. Metallurgical factory contamination influenced the lipid peroxidation in the first place, oil refinery, motor building and accumulator factories impacted lipid peroxidation in the second place.
