How much dust is there floating in the atmosphere? Up to five billion tons every year, a geologist says

Tomáš Hrstka, the current leader of the Atmospheric Dust Project of the Strategy AV21 programme, was invited to Czech Radio to talk (in Czech) about the present trends of this hazardous component in our everyday environment. At this occasion, he also mentioned a new technique which has been applied: fully automated, high-throughput analyses of element and mineral compositions applied to samples of dust deposits. Tomáš Hrstka has significantly contributed to the development of these techniques internationally.
