Abstract

This study evaluated the magnetic properties magnetic susceptibility and isothermal remanent magnetization IRM of tissue samples from the brain liver spleen pancreas heart and lungs resected from human corpses with the aim of identifying the magnetic mineral structures and understanding their possible connection to diseases professional activity age and gender of the individual smoking habits and the environment The heart was the organ with the highest values of magnetic susceptibility and the pancreas showed the lowest values No relationship was found between magnetic susceptibility IRM values and ages of the individuals However the samples obtained in females showed lower values of magnetic susceptibility than those resected from males The samples collected from the lungs of smokers have higher values of magnetic susceptibility and IRM indicating the presence of magnetic particles with an anthropic origin Moreover the complexity of the magnetic behaviour of these tissues may suggest a contribution of both biogenic and anthropogenic magnetic particles also due to some professional activities In the brain a heterogeneous distribution of the magnetic susceptibility values was found which might be related mainly to the diamagnetic behaviour of myelinrich structures This study suggests that although the diamagnetic and paramagnetic behaviour is common to all structures magnetitetype structures are always present in the tissues and hematitetype structures may also contribute to the magnetic signal of the sample IRM values are only dependent on the presence of magnetite or hematitetype magnetic structures and so this technique seems more suitable to achieve the characterization of biomagnetic structures than magnetic susceptibility
