Industriales comunes polvo - Fotografía de stock

Technically, this image is not a photograph, since it was not originated by light ("photo") but by an electron beam: the image was captured by an Hitachi ultra-high-resolution Analytical FE Scanning Electron Microscope SU-70. it is a huge magnification of the common dust of industrial outdoor environments. Badly for us, this dust is rich in polluting and corrosive elements, such as chlorine and sulphur.
