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.

Friday's Comments

If anyone has noticed that they have a few more sniffles today the pollen and spore level is probably to blame. We have high levels today in both aeroallergen pollen and fungal spores. Our local ragweed took advantage of the beautiful conditions yesterday and released pollen abundantly. The high humidity along with the recent rainfall also portends great conditions for fungal spore germination so those organisms are filling the air with spores. Fortunately the clouds and cooler temperatures are keeping the ozone in check. Otherwise today would have a triple whammy for respiratory difficulties.

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.
