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

Our airborne grass pollen levels continue to decrease as we get into summer. The turbulent winds aloft are bringing in an unusual mix of pollen by long distance transport. The most concerning thing is the mold count remaining at the moderate range. The warm winter and early spring we had this year resulted in an early start for many fungi. As we go through wet cycles our spore potential builds until cold weather returns in the fall. Having a moderate spore level in a relatively dry part of the summer means that we have an increased probability of a lot of very high spore levels in September.

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.
