Yes. Volcanic ash falls into the air pollutant category of particulate matter. It can cause respiratory and eye symptoms during and after ash fall. The ash contains the minerals quartz, cristobalite, or tridymite. These are free crystalline silica which may cause silicosis which is a disabling and potential fatal lung disease. The recommended respirable exposure limit of 50 ug/m3 of particulate in air can be exceeded for short periods of time.

What are some long-term effects of volcanic eruptions?
Air pollution is a major effect of volcanic eruptions. Over the last few years Mount St. Helens has been the number one pollution source in the Northwest.
Are volcanic gases natural sources of air pollution?
Yes because volcanic gases release a gas that is harmful and basically started air pollution.
How far in the air could volcanic ash travel?
Volcanic ash plumes can exceed 20 miles in height and travel for thousands of miles.
Why did the volcanic ash go in the air not on the ground?
The volcanic ash goes in the air because, they are air-borne materials/particles, and can easily and conviniently be carried and transported by wind, since they are light and not as dense as lava.
What is the principal source of air pollution from volcanoes?
ash
What are three natural sources of air pollution?
pollen, ash from fire and ash from fire.
What was the next form of pollution after volcanic eruptions and forest fires?
air pollution and molten gas
Why does volcanic ash cloud rise?
volcano ash clouds rise because hot air rises to the sky and cold air rushes in from the sides .
