Laser particle counts are the number of particles per cubic foot divided into 6 different size ranges. A laser beam literally counts the number of such particles as they are sucked past a detector. There is evidence that increased numbers of particles, particularly in the smaller ranges, are associated with heart diseases. That is why we measure it.

Thursday's Comments

Like many of us, pollinating trees are also still under Mother Nature’s cold spell this morning! But yesterday’s mild temperatures, light breezes and partly sunny skies were good help for airborne pollen distribution. And so, most of our local trees are releasing pollen into the air as best as could in hopes of producing an abundant crop of seeds during the summer resulting high pollen count today in our area.

Pollen and mold counts are collected at Children's Mercy Hospitals and Clinics Hospital Hill location using a Hirst spore trap manufactured by Burkard Limited. Results are expressed as the mean value of the particles per cubic meter and represent an integrated 24 hour collection. These results may be published for media purposes provided the Children's Mercy Hospitals and Clinics logo is used to acknowledge the source. Written authorization must be provided for commercial use of the results. For a recorded count, call (816) 346-1331.
