Evidence of small ferrimagnetic concentrations in mice (Mus musculus) livers and kidneys exposed to the urban dust: A reconnaissance study

Previous investigations carried out on Mexico City urban dust and soils revealed relatively high concentration of heavy metals due to the atmospheric pollution. Detailed magnetic analyzes demonstrated that the dust samples contain neo-formed magnetite phase coming from the vehicles combustion. Here,...

Detailed magnetic analyzes demonstrated that the dust samples contain neo-formed magnetite phase coming from the vehicles combustion. Here, we report the results of magnetic measurements carried out on Mus musculus livers and kidneys in order to evaluate whether the magnetic particles may penetrate and accumulate in these organs. The systematic measurements of the magnetic susceptibility and isothermal remanent magnetization acquisition curves attest the existence of small concentrations of low/medium coercivity ferrimagnetic grains (most probably magnetite). This study confirms that fine magnetic minerals can penetrate and reach livers and kidneys of mice in relatively small concentrations.Investigaciones previas llevadas al cabo sobre el polvo y los suelos urbanos de la Ciudad de México revelaron una concentración relativamente alta de metales pesados debido a la contaminación atmosférica. Los análisis magnéticos detallados demostraron que las muestras de polvo urbano contienen una fase de magnetita neoformada procedente de la combustión de los vehículos. En este trabajo informamos los resultados de las medidas magnéticas realizadas en hígados y riñones de Mus musculus para evaluar si las partículas magnéticas pueden penetrar y acumularse en estos órganos vitales. Las medidas sistemáticas de la susceptibilidad magnética y las curvas de adquisición de magnetización remanente isotérmica atestiguan la existencia de pequeñas concentraciones de granos ferrimagnéticos de coercitividad baja / media (muy probablemente magnetita). Este estudio confirma que los minerales magnéticos finos pueden penetrar y llegar a hígados y riñones de ratones, en concentraciones relativamente pequeñas.Universidad Nacional Autónoma de México.
