Kudzu Contributes to Air Pollution

By Charlie Nardozzi

As if there weren't enough reasons to dislike this ubiquitous Southern weed that is migrating northward with global warming, now it appears kudzu emits gases that contribute to air pollution.

Researchers at the University of Virginia have determined that kudzu emits gases that contribute to the formation of ground level ozone, or smog. The major manmade sources of ground level ozone are cars and coal-fired power plants. While some growing plants also contribute to ozone pollution, kudzu appears to produce these gases faster and in larger quantities. It's not clear whether kudzu is producing enough gases to warrant a widespread eradication program. Presently kudzu covers more than 11,000 square miles, mostly in the Southeast, and is spreading up to 200 miles each year.
