Health Hazards of volcanic ashes yet to be known!

WHO stated that the health hazards of volcanic ashes from the volcanic eruption in Iceland are not known yet. However, volcanic ashes could have negative effects on people with bronchial asthma and other respiratory problems.

WHO says that 25% of the ashes are of particles less than 10 microns. Particles which are less than 10 microns can go deep into the lungs and cause trouble. Particles have not yet started to precipitate.

WHO has advised people to stay indoors as much as possible.

The effect of volcanic gas on Sri Lanka is unlikely, considering the long distance from the site of explosion.
