Spring's bloom may not smell so sweet anymore, as pollutants from power plants and automobiles destroy flowers' aromas, a new study suggests. Researchers at the University of Virginia created a mathematical model of how the scents of flowers travel with the wind. The scent molecules produced by the flowers readily bond with pollutants such as ozone, which destroys the aromas they produce.
So instead of wafting for long distances with the wind, the flowery scents are chemically altered. Essentially, the flowers no longer smell like flowers. Bees depend on flower nectar for food, and if they have a hard time finding the flowers, they can't sustain their populations. Other studies, along with the experiences of farmers, have indicated that bee populations are dropping in places such as California and the Netherlands.
