281 Symposium--Minerals, Nanoparticles, and Health: I

Oral Session
S09 Soil Mineralogy Natural and synthetic minerals including nanoparticles can have both beneficial and adverse effects on human and animal health. Many minerals can convert biological and synthetic toxins to nontoxic or less toxic forms through degradation or adsorption. Poisoning due to Pb, Se, As, Tl etc., silicosis, asbestosis, and fluorosis are frequently reported. Understanding the interactions of minerals and nanoparticles in the environment and the impact of the minerals to human and animals are critical for both preventing the adverse effects and for exploring the use of minerals to alleviate the problems.
