Coal fly ash nanoparticles induced cytotoxicity and oxidative DNA damage and apoptosis in Chang liver cells

Coal is the main source widely used for electric generation and industrial applications due to its low cost and abundance of this fuel. Exposure to coal fly ash particulate matter (CFA-PM) is a major health concern in developing countries. The in vitro cytotoxicity, oxidative DNA damage and apoptosis of coal fly ash nanoparticles (CFA-NPs) were determined by lactate dehydrogenase (LDH) enzyme, reactive oxygen species...
