Pollen stays in the air after spring rain

Recommended Posts

Still Waters

If you're waiting for the rain to wash away the pollen and alleviate your allergy woes, you may be barking up the wrong tree - in springtime, at least. New research has found that spring rain can generate more pollen problems than it solves.

Measurements of pollen in the air during and after spring rainfall has found that bits of pollen can remain airborne for up to 11 hours - presenting a previously unconsidered potential breathing hazard for people with allergies and asthma.

The researchers found two distinct effects. Firstly, the rain did indeed suppress whole pollen grains, just as expected. But the team's measurements found a significant increase in fragments of pollen grains.
