Raman studies of the interactions between Dipalmitoylphosphatidylcholine (DPPC) liposomes and PCBs molecules

Polychlorinated biphenyls (PCBs) are common environmental contaminants arising from industrial sources and from waste incinerators. PCBs show long term toxic, neurotoxic, and carcinogenic effects; they dissolve and concentrate in the fatty tissues of living organisms, as muscle fat, brain, liver and lungs [1]. It has been observed that PCBs can interact with cell membranes in erythrocyte [2] and the interaction with the biomembranes could be an important step in the transport to the target tissues and in the development of their toxicity.
