The inhalation of lead oxide nanoparticles (PbO NPs) severely damaged target organs of exposed mice. Our optimized LC-MS method was used to compare the profile of lipids extracted from a control lung cell line (and lung tissue from control mice) compared to lung cells and tissue from mice exposed to elevated concentrations of airborne PbO NPs. Our study revealed a possible association of alteration of cholesterol metabolism after exposure to metal NPs.
