Pollen Count

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

There was a great increase in the amount of grass pollen in the air today. Kansas City is on the edge of the great Western prairie so it is ideally suited for growing grass and the fields and meadows around Kansas City are filled with grass plants. . As we go through grass season the species of grass in the collection will change. But under the microscope all of the grass pollen looks alike so we will not identify the species of grass. However for the grass allergic person, all the grasses are pretty much the same. Anyone who is grass allergic would have noticed that they have increase symptom including runny, itchy noses and watery eyes.
