The depth of penetration of dust and percent deposi tion in the human lung depend on the size of the dust grains [3–5]. In addition to grainsizedriven lung deposi tion, the toxicity of a mineral dust is also affected by its crystalline structure, chemical composition, and reactive surface areas.
The ocean floor. The distribution of iron in the oceans is likely to be a way of trapping excess atmospheric CO 2. On the one hand, global warming could increase winds and therefore dust production, but then more dust could enter the ocean, potentially providing a natural mitigator to those effects.
