Flowers' Smell Not Traveling As Far

Ant writes in to note a study indicating that, because of air pollution, the smell of flowers is not wafting as far as it once did. Pollutants from power plants and automobiles destroy flowers' aromas, the study suggests: "The scent molecules produced by flowers in a less polluted environment, such as in the 1800s, could travel for roughly 1,000 to 1,200 meters; but in today's polluted environment downwind of major cities, they may travel only 200 to 300 meters." The finding could help explain why some pollinators, particularly bees, are declining in certain parts of the world.

    try flowers from one of the organic stores or Whole Foods. they smell a lot better and stronger than pretty much all other flowers i've ever bought

    If it's any consolation: neither do my sister and my father (though my sister can still smell extremely strong aromas). Especially troublesome is the lack to smell natural gas or smoke.

    The problem seems to be not drowning the scent in other scents, but the destruction of scent molecules by pollutants. Insects have a very low scent threshold and can detect a scent trail of just a few specific molecules, so drowning wouldn't be a problem.

    We have two types of bees in this world - domestic and wild. No, we have 1 species of domestic bee, and thousands of species of wild bee.

    And both are declining dramatically (there's an area in china that apparently has no bees left at all - the farmers there who grow pears for a living have to hand-pollinate otherwise there would be no more crops).

    Ironically, Natural Gas has no smell, it's added, but we all got what you meant, I'm sure.

  7. So without reading the article you're the expert? by jensend · · Score: 3, Informative

    Nonsense. They're suggesting that the relevant effects from pollution aren't just local in the area of the polluters. Furthermore, colony collapse disorder, which is the crisis you refer to, affects both wild and domestic bees and is very poorly understood - it's certainly not been proven to be due to disease or mites, and there's no good reason to immediately jump to the conclusion that the problem mentioned in the study isn't a major or even dominant factor in colony collapse disorder.

  8. colors by slashkitty · · Score: 3, Informative

    That's real interesting, but bees and many other pollinators find the flowers through the color. Granted, pollution may be diminishing the color, but I'm sure they can still find them. Once found, the bees give directions to the hive.

    By the time (i.e. concentration level) you can smell H2S, you are in big trouble. Then your sense of smell goes and you think you are alright again, I guess. In short, not the greatest stench compound.

    There's a lot of conspiracy theories about these collapses but the IAPV virus was found in over 95% of collapsed hives. I know its much more hip to blame humans, pollutants, wifi radiation, lack of bee tin foil hats, etc but this is just nature vs nature.

  11. Re:From the gut feeling dept. by afidel · · Score: 2, Informative

    Yes but IAPV is also very common in non-collapsed hives so it is believed that it has to be a combination of factors with IAPV being but one (possibly major) factor.
