Silica and aluminium in the lungs of feral pigeons and experimental rats exposed to studded tire-generated road dust
Abstract Feral pigeons' lungs in Sendai, where particle levels were high in winter due to the use of studded tires for automobiles, and in Tajiri, where air was clean with no noticeable increase in dust level throughout the seasons, were examined for the element levels as indicators of air pollution. Aluminium, Pb, Si, Ti, and possibly Cd levels in the lungs were significantly higher in Sendai pigeons than in their counterparts in Tajiri, and the blood levels of Al, Pb, Si, and Ti were also higher in the former than in the latter. Experimental exposure of rats to dust-loaded outdoor air for a three-month period in the winter season in comparison with exposure to the filtered outdoor air and clean animal room air disclosed that the elevation of Al and Si was observed only in the rats exposed to the dust-loaded air, suggesting the deposit of airborne particles in the lungs.
