Correction to: Particle toxicology and health - where are we?

After the publication of this article [1] it was hihglighted that the number of deaths related to natural disasters was incorrectly reported in the second paragraph of section Hazards from Natural particulates and the evolution of the biosphere. This correction article shows the correct and incorrect statement. This correction does not change the idea presented in the article that from an evolutionary view point, natural disasters account only for a small fraction of deaths on the planet. The original article has been updated.
