LIPID PEROXIDATION CAUSED BY THE BRAKE WEAR DEBRIS AND CHOSEN CONSTITUENTS OF FRICTION COMPOSITES
Popis výsledku v původním jazyce
Brake processes have been extensively studied and discussed in the relation to the creation of the brake wear. However, the contribution to the environmental pollution is still not clear and there is not unified procedure for the evaluation of the potential risk of the brake wear to the environment and human health. Lipid peroxidation, which could be defined as the oxidative deterioration of lipids containing any number of carbon-carbon double bonds especially polyunsaturated fatty acids, is one of the markers of oxidative stress and linoleic acid as a model lipid of cell membrane is used to quantifying the potency of tested compounds to induce peroxidation damage (lipoperoxidation) of unsaturated lipids. The aim of the study is evaluation of the potential toxicity of brake wear debris and typical constituents used in formulation of friction composites for brake linings by cell-free chemical test. For quantifying of lipoperoxidation was used test based on the reaction of malondialdehyde (natural product of lipid peroxidation) with thiobarbituric acid to produces pink adduct. Brake wear debris from commercial available brake pads and reference friction composites were collected after standard brake dynamometer test. Lipoperoxidation was evaluated for the collected brake wear debris and for chosen compounds commonly used in brake formulations (titanate, barite, iron fibers, bronze fibers, and chromite). Both types of brake wear debris were analyzed by scanning electron microscopy and Raman spectroscopy. Experimental results showed slightly toxic character for chromite, iron fibers, barite, and brake wear from reference friction composite.
