Hypoallergenic parks? Really?

On the face of it, this sounds nutty--parks that don't make people's allergies and hayfever worse.

But it is not nutty--a professor of botany at the Univ of Grenada, Spain, is studying how trees in green spaces contribute to or cause allergies. (J of Environmental Science, special section)

She and all her siblings suffer from allergies. They are immersed in this subject. The city of Grenada is her lab. It has one of the highest pollen counts in the world.

They classified all the trees in Grenada's parks and green spaces. They recorded the type of pollination, the length of the pollination period, and the potential of each tree for causing allergies.

Surprise--many of the most common trees were the worst offenders.

They also learned that allergies were never considered in designing these spaces.  In the future, she says, urban green spaces can be "comfort islands." Not only would they not cause or make allergies worse, the could even clean pollutants out of the air.

So maybe it sounds nutty to try to make the out-of-doors allergy-free, but this woman said, hey, why not?
