Abstract:
The health consequences of sand particle inhalation are incompletely understood. This project evaluated the respiratory toxicity of sand particles collected at military bases near Fort Irwin USA, in Iraq Camp Victory, Taji and Talil, and Khost Afghanistan. Our primary focus was on assessing the role of soluble metals in the respiratory toxicity of the sand particles using in vitro and in vivo methods. Replicating rat type II alveolar cell cultures RLE-6TN were exposed to sand extracts or vehicle control in serum-free media for 24 h. Cytotoxicity was determined using the 3-4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide assay and assessment of lactate dehydrogenase leakage.
