RESUMEN
El asbesto es un mineral fibroso conocido desdeantiguo, utilizado ampliamente en la industria debido asus propiedades físicas y químicas que lo hacen muyadecuado para dicho fin. Los tipos de asbesto se clasificanen grupo serpentina y en anfiboles según la configuracióncurvada o recta de sus fibras. En cuanto a suspropiedades destacan la resistencia al calor, al desgaste,a los álcalis y ácidos y su flexibilidad entre otrascaracterísticas que lo hacen un material adecuadopara ser utilizado como aislante, en la industria textil yen otros muchos campos. Es conocido desde haceaños el riesgo patogénico del amianto al permanecertiempo en el tejido pulmonar, atribuyéndole según losestudios la alteración de la actividad mucociliar delhuésped, la activación macrofágica y la liberación demediadores inflamatorios así como un aumento de supoder oncogénico al asociarse al humo del tabaco eincluso a ciertos virus
ABSTRACT
Asbestos is a fibrous mineral that has been knownsince ancient times. It is widely used in industry due toits physical and chemical properties which make ithighly suitable for this end. Asbestos is classified intwo groups - serpentine and amphibole - depending onthe curved or straight configuration of their fibres.Outstanding amongst its properties are its resistanceto heat, wear, alkalis and acids, and its flexibility,amongst other characteristics, which make it a suitablematerial for use as insulation, in industrial textiles andin many other fields. The pathogenic risk of asbestosremaining for a long time in the pulmonary tissue hasbeen known for many years; studies attribute it withalteration of the mucociliary activity of the host,macrophage activation and the freeing of inflammatorymediators as well as an increase in their oncogenicstrength on association with tobacco and even someviruses
