Research progress of silica nanoparticles effects on lung-injurious
With the widespread use of silica nanoparticles(SiNPs)in agriculture,biomedicine and building materials,the risk of its population exposure are increasing.Many studies have shown that SiNPs could cause lung damage and are poten-tially toxic to other organs.However,the mechanisms of its toxicity has not been fully elucidated.The present review summa-rizes the characteristics of SiNPs and its environmental exposure and illustrates the toxicity mechanism of lung injury caused by respiratory exposure of SiNPs.
