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

As far as the actual numbers are concerned there are fewer grass pollen in the air today than there were tree pollen a few weeks ago. However grass pollen grains are filled with small starch granules and protein allergens. These grass pollen have a tendency to break apart and spill their contents into the air. All of this tiny allergenic material can get deep into the lungs of grass allergic people and cause some pretty severe symptoms. When you see people today with red eyes and runny noses you can be pretty sure they are suffering the effect of all the grass pollen we have in the air.

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.
